Quarter 3: Science 8 Week 4 | Conditions for Storms | MATATAG Curriculum

Okay. So, welcome grade 8 students.

Okay, so this week is for week number

four ano and I hope you enjoyed our

lessons from week number two and 3.

Okay, types of eruption and types of

volcano. So, mga mam pinagawa ko kasi

sila dito ng mga bulkan e and then

pina-erupt namin ah in the class and

then they really enjoy it. Okay. So

hopefully naman. Okay. And then next

year may mga ganun pa din tayo. Okay? Sa

grade 8 pa din. Hopefully sa grade 8 pa

din ako next year ano. And for today's

lesson, we're going to talk about

storms. Okay? Yes. Okay. You've heard it

right. Let's dig deeper and understand

them even better. Okay. So since our

country is prone to typhoon or uh

storms, okay, mas maganda na mas

maintindihan ninyo yung mga anak kung

papaano ba sila nabubuo or ano yung mga

conditions for it to be. Okay? So I am

Sir Wawi, Rever Curious Science Buddy.

Don't forget to like, share, and

subscribe para lagi kayong updated sa

mga susunod pang videos. All right,

let's begin. So our topic for week

number four it's like um what do you

call this preparatory topic kasi medyo 3

weeks natin okay na idi-discuss yung

about typhoons like

formation of typhoons, parts of typhoon

and then the typon prepare preparedness.

Okay? So madali lang naman siya. Ayan.

So for our topic it's about condition

for storms. Ayan for the learning

competency, gather information from

secondary sources to explain how

typhoons develop and why the Philippines

is prone to typons. And for our learning

objectives, locate the Philippine area

of responsibility in the map. Explain

why the intertropical convergence zone

or the ITCZ is a factor for storm

formation. And then three, determine the

conditions needed to form a typhoon. Ano

ba yung mga conditions or factors for a

typhoon to be formed? And then number

four, differentiate the types of

tropical cyclones. Okay? And then number

five, identify the parts of a typhoon.

Actually, iyung parts of a typon is um

hindi natin dito madi-discuss to be

specific, it is part of week number

five. Okay. And then number six,

describe the situation in each storm

signal wording. Similar din ito. Okay?

Hindi rin natin siya mata-touch. Okay?

Part siya ng week number ah five, okay?

Or six. I'm not sure about that. But

hindi natin siya possible or hindi natin

siya madi-discuss dito. So ang atin

lang, sinunod ko lang po kasi yung nasa

le kung ano yung objectives doon. So

possible yung ating ma explain yung sa

Philippine era responsibility, the

intertropical conference zone. Okay? And

then yung ating types of tropical

cyclones together with the conditions.

Yun yung highlight ngayon sa ating

discussion. Conditions needed to form a

typon. Okay? So pwede nating i-erase

yung 5 and six if you want. Okay? So for

our review, okay, part of our review,

layers of the atmosphere. And I know

that you are already familiar with the

different layers of atmosphere, right?

Grate. Okay. So sige. Okay. So for its

description we have okay altitude is

zero from the earth surface to 12 km. It

varies up to 8 km at pols okay 18 km at

equator. Okay. So for notes, it's the

closest layer to earth surface. It

contains 75 to 80% of atmosphere's mass

and all weather events. Okay. And then

clouds like rain, storms will cure here.

And then the temperature decreases with

altitude about 6.5°

celsus per km. Okay. So what layer is

being described in this um slide?

What do you think? It's correct.

Okay, it's the troposphere. Okay, so

ayan po. And then nandiyan din po

lumilipad sa troposphere yung mga

parachute. Okay. Dumadaan yung mga

airplane, something like that. Okay. And

then the clouds, the rain. Okay. So

next, what about this one? So for its

altitude is ranging from 12 to 50 km.

Okay. Altitude mga papataas. kung gaano

sila kataas. Okay. It contains the ozon

layer which absorbs harmful UV

radiation. So ozon layer in chemistry O3

ano which absorbs harmful UV radiation.

And then sabi dito airplanes fly in the

lower stratosphere okay or sort of

troposphere ano to avoid turbulence.

Okay. So next temperature increases with

altitude due to ozone absorption of

ayan. So what layer is this? Okay. What

layer is being described in this slide?

What do you think? Correct. It's

ayan

the stratosphere.

Okay. So the stratosphere tandaan natin

sa stratosphere nandiyan 'yung ozen

layer. Okay. Next layer. Okay. Altitude.

Okay. From 50 to 85 km. It's the coldest

layer of the atmosphere up to 90° celus.

It protects Earth by burning up atmers.

Okay. And then temperature decreases

with altitude.

Okay. So ayan the massosphere. Tandaan

natin. It's the coldest layer because it

burns up meteors. Okay. Next.

Okay. Altitude from 85 to 60 km. It's

very hot up to 2000° Celus or more

because it absorbs high energy, solar

radiation and of course Aurora or the

northern and southern lights occur here.

Okay? Kasi nga bakit po nagkakaroon ng

northern and southern lights? Because in

this part mayong mga charged particles.

When they interact, okay, or nagkakaroon

sila ng interaction, nakaka-create sila

ng mga lights. Okay? And then satellites

and the international space station

orbit in this radian region. Okay. What

layer is this? It's the thermosphere,

ano? Okay. And next, altitude from 600

km to 10,000 km gradually merges into

outer space. Kumbaga ito na yung

pinaka-last. The outermost layer of the

atmosphere, air is extremely thine and

atoms and molecules can scape into space

mainly composed of hydrogen and helium.

Okay. What layer is this? Correct. It's

the excess, the outermost. layer kumbaga

ito na yung pinaka um what do you call

this merge uh it merges into outer space

na papunta na sa outer space and so

hopefully na-refresh tayo d sa layers of

atmosphere okay ayan so bakit ko ba yan

diniscuss or inintroduce dito may

kinalaman po ba yan sir of cours and so

where do storms form in the atmosphere

also in the layers of the atmosphere

saan po nabo yung ating storm

Okay, nandiyan na po yung sagot. Hindi

ko na itos

fear. Dapat po arelete ko ano. Okay. So,

sorry that's in the trophosphere. Sorry

for that. Okay. It's in the

trophosphere. Tandaan natin, storms form

in the trophosphere which is the lowest

layer of the atmosphere. Okay. Kumbaga

nandi yan yung mga water disturbances.

Okay, since okay, nandiyan yung mga

formation ng clouds. Okay, so tandaan

natin ang storms po ay nabubuo sa

troposphere. Okay, next.

So, before we begin, meron po akong

video ah video or before kayo

mag-continue. Meron po akong four videos

na nandon sa ating description.

Hopefully mapanood niyo muna before tayo

before ninyo i-continue na manood ng

video kasi it's important for you to

understand what I'm talking ah what I'm

talking here ano. So hopefully panoorin

niyo muna bago tayo mag dito sa ating

lecture or magpatuloy. So nasa link po

okay or nasa description ng ating video

yung link ng bawat video kasi pa ako

pwedeng mag-play dito baka tayo

ma-report. Okay. So, what is the role of

air pressure and temperature in the

typon formations? Okay. So, meron po

bang role or may factor ba? Okay. Yung

ating pressure and temperature in the

formation of typhoon.

Okay. So, of course, ayan. So the answer

is yes. Okay. So meron pong kinalaman or

merong role na ginagampanan yung

pressure and temperature in typhoon

formation because warm air rises. Okay?

Warm air rises. Okay? Low pressure

forms. Okay? So sa low pressure area,

okay? Umaangat, okay? Or tumataas yung

ating air or warm air. Okay. And then

pag nag uh tumaas yan, it will cause

strong winds and rain. Kasi nga habang

tumataas yung ating warm air, okay, the

air or the regions in that part becomes

cooler, okay? And then it the molecules

in that part expands. Okay? So yun yung

pinaka-reason. Okay. Kung bakit sa ating

low pressure area, okay, nabubuo yung

ating mga storms. Okay? So ipapaliwanag

ko pa rin naman yan later kung ano ba

yung kinalaman ng pressure, okay sa

formation ng typhoon. Okay. And then how

does the latitude of a place relate to

its temperature? Okay. Air pressure. How

does the latitude of a place rate to its

temperature or air pressure? The answer

is near the equator. Sa atin sa equator,

it's too hot and low pressure. Okay.

Nearp, cold and high pressure. So in

this part, okay, in this part ha or

papipiliin ko kayo low pressure and high

pressure, saan diyan possible mabuo yung

ating typhoon or storms? In low pressure

or in high pressure? Correct. Okay. In

low pressure area. Okay. So kadalasan

din yan or madalas talaga nandiyan po

nabubuo yung ating mga typon sa low

pressure area. Okay? Ang high pressure

kasi mga anak it can cause clear sky.

Okay? Yung mga ganyan sa high pressure

natin. Sa low pressure ito yung may mga

cloudy. Okay yung paligid. Okay kasi nga

tumataas yung warm air expands. Okay the

region and that part becomes cooler.

Okay so next. So for our activity number

one decoding storm conditions. So at the

end of the activity students will be

able to identify and understand key

terms related to the conditions

necessary for a storm formation by

decoding hidden words using number

letter substitution. So nagawa na naman

natin ito. Okay? So parang magde-decode

lang tayo. Ano? So this one, A is for

number one, B is for number two, and so

on and so forth. Okay? So kumbaga

ide-decode niyo lang for you to come up

in the correct word. Okay? So are you

ready? So let's start. What about this?

Okay. So raise your hand or you just

have to try this. Pause the video para

makapagsagot.

Correct. It's adiabatic temperature

change. Okay. Next.

Correct. It's air pressure.

Next,

it's altitude. Okay. Next,

humidity. What about this one?

Correct. It's intertropical convergence

zone.

What about this one?

Low pressure area.

Correct. Okay. It's pag-asa.

What about this one? Storms. Okay. And

then okay, we are done in that. So

syempre we those words are related to

our discussion and of course okay

di-discuss natin yun one by one ano. So

for our activity number two, sharing

insight and storm vocabulary. Let's uh

explain those vocabulary words. Okay. So

at the end of the activity students will

be able to explain the meaning of key

decoded vocabulary words and discuss

their importance in the conditions for

storm formation. So magsisimula muna

tayo sa adiabatic temperature change.

Ano ba yung tinatawag nating adiabatic

temperature change? Okay. So it means

that it is a cooling or heating of air.

Cooling or heating of the air caused by

the contraction or expansion or

expansion of air molecules as opposed

the loss of gain or heat. Okay? Sabi

diyan, "When air rises, it goes to a

place where the pressure is lower. It

expands and becomes cooler. Just what

just what I'm talking earlier. Okay. So

in a low pressure area, okay, or low

pressure, yung air is nagra-rise, okay?

Tumataas, okay? And then when it uh

rises, okay, the molecules expands and

the region becomes cooler. Okay. Kaya

nabubuo or ito yung pinaka parang good

conditions for a storm to B4. Kaya ano

naman 'yung opposing site niya? Okay.

When air sinks, it goes to a place where

the pressure is higher. It gets

compressed and becomes warmer. Okay? Ito

naman sa when air sinks. Okay. Sa higher

pressure area naman ito. Pag nag-sink sa

higher pressure area, iyung ating air is

nagsi-sink. Okay? Yung ating mga

molecules nako-compress and the regions

become warmer.

Okay, tatandaan natin. But in overall um

an overall what do you call this? Uh

event or occurrence, okay, yung ating

cooling and heating of air is known as

adiabatic temperature change. Okay?

Which occures when air rises and when

air sinks. Okay? So sige. So meron pa ba

tayong idadagdag dito?

Okay. So wala na naman. So next we have

air pressure. Ano naman yyung air

pressure natin? Okay when we say air

pressure the amount of force exerted on

a unit surface area. Okay? High

pressure, low altitude. Okay? Air is

squeeze. Okay? Nai-squeeze.

Okay? Nako-compress yung ating mga

molecules. Okay? Molecules become close

and yung effect, yung region nagiging

warmer. Okay. In um low pressure area,

yung ating low pressure area, kadalasan

yan ay nandon sa high altitude. Air

expands, then the molecule spreads out

and then the region become or becomes

cooler lumalig. Okay? So that's the main

difference. Okay. Meron tayong high

pressure at meron tayong low pressure

area. But in the two, okay? Saan po yung

good condition for a storm to be formed?

In a low pressure area? Tatandaan natin.

So sabi diyan, air pressure is simply

the force of air. Okay? Pushing on a

surface.

Okay. Tatandaan natin that in a low

pressure area lagi ang nasa high

altitude. Ano? Okay. Altitude. Okay.

Causing the air to rise. Okay. And then

yung molecules mag-spread out. Okay. The

regions become cooler. In high pressure,

low altitude lagi. Okay. Yung ating

molecules, yung air natin na-squeeze

causing the molecules to become close

and then making the regions become

warmer. Okay.

Ayan. Parang this one. Okay. Tingnan

natin yung molecules. When molecules

rises, it expands.

Okay. When uh air sinks,

okay, it becomes compress. Parang ganun

lang ating scenario. Nakukuha? Ayan.

Next. Altitude.

Okay. So, altitude lang. Okay. It's the

height above Ca level. Okay, tandaan

natin the height above Ca level, the

higher you go, of course, the cooler it

gets dahil syempre bumababa ang

pressure. Okay? Tig nga ang pressure,

low pressure is nasa high um altitude.

Okay? So tatandaan natin, altitude is

the height above Ca level. The higher

you go, the cooler it gets. Dahil nga

sabi nga natin bumababa yung air or

pressure. Okay? So height express as the

distance above a reference point which

is normally sa level or ground level.

Okay. It pertains to height lang namin.

Okay? Ayan.

Next.

Humidity. Okay. The degree to which the

air is charged with water vapor, this

may be expressed as an absolute

humidity, relative humidity and specific

humidity. Okay? So dito sa humidity the

amount of water vapor in the air. It's

the amount of water vapor present in the

air. Okay? It can be yun nga sabi ko

absolute relative or specific. So iyung

atin the higher the humidity the more

moist the air fail. the air fills. Okay?

Kumbaga 'ag mataas ang humidity parang

um ma-moist 'yung buong region. Okay?

Pag nangyari 'yun, ibig sabihin parang

mataas 'yung humidity. Okay? Pag mataas

'yung humidity mga anak, kadalasan ah

let's say nagpapawis tayo, mga ganyan.

Okay? Pinagpapawisan.

Okay. Next.

Pag-asa. Okay. So ano naman yung

pag-asa? Okay. Pag-asa is the Philippine

Atmosphere Geophysical and Astronomical

Services administration is responsible

for the provision of weather forecast

and tropical cyclone cyclone warnings,

flood bulletins and advisories and

hydrological, climatological and far

weather forecast. Okay. Kumbaga ito yung

agency sa Philippines. Okay. This is the

our agency or official agency na

nagmo-monitor ng weather, typhoons and

storms, even the flood advisories, ano.

So lahat ng warning about bagyo galing

sa kanila. Okay? It's Pag-asa. Tandaan

Philippine Atmospheric, Geophysical and

Astronomical Services Administration.

Okay. Pagbagyo, pag-asa. Okay. So next.

Ayan.

So a storms, okay storms is the

atmospheric disturbances that are

typified by lightning, thunder, heavy

precipitation and powerful winds.

Examples, tornadoes, blizzards, okay,

and tropical cyclopes are examples of

storm forms. Okay? So yung ating storm

are atmospheric disturbances, ano? Okay

na merong mga lighting okay and then may

mga dalang thunder and strong weight.

Okay. So kadalasan yung storms natin

dito sa Philippines we have typon. Okay.

Next we have intertropical convergence

zone. Ano naman yyung intertropical

convergence zone? An area close to the

equator where the trade winds and the

northern

winds of the northern and southern

hemisphere meet. I ating wind from the

northern and southern hemisphere meat.

'yung area kung saan sila nagtatagpo is

known as the intertropical

convergence zone. Okay? Yung wind po

galing sa north and then sa south ay

nagme-mit. Kung yung area kung saan sila

nag-met is the intertropical convergent

zone. Okay? Pag nagme-meet sila, okay,

napapansin natin pwedeng maka-form ng

mga clouds and it can create, okay,

storms. Okay, thunderstorms. Okay. And

ito yyung area, okay? Ito yung din

nakakatulong nung ating ITZ. Okay. Is a

factor kung bakit nakakabuot tayo ng mga

bagyo, okay? Or typon. Okay. Sabi diyan

'yung ITCZ natin is 'yung zone na

malapit sa equator. Kung makikita natin

'yung red line. Okay. So it is near the

equator where the trade winds from the

north nga. Okay. And then south pyramid.

Okay. So yung area na iyon has warm

ocean water and intense sunlight. Okay,

because of this air in the ITCZ becomes

warmer and more humid. Okay. So, the

converging trade winds, nagco-converge,

nagme-mind, push the warm air upward.

Pinu-push nila. Okay. Pag nagbanggaan

yung dalawa, pinu-push nila yung air

upward causing a chain of convection

process. 'Di ba? Pag nagra-rise ang wind

or yung air rises, it will create what?

Low pressure area. Kasi pag nagtaas yung

wind, tumaas, umangat, okay, the

molecules will expand and the region in

that parts become cooler. Okay? So yun

iyung pinaka-perfect condition for a

storm to be form. Ayan. So sige. Okay.

Sabi pa dito, ano pang sinasabi yan? The

converging trade push the warm air

upward. Kaya nga causing a chain of

convection process. yung it the air

rises, okay, it expand, it cools. And

then pag nag-cool down yung air area na

yun, it can form clouds. Kaya nga yung

nakita ninyo kanina, clouds or bands of

clouds and then will okay ano po okay

release, a rain, okay and then thunder

storms. So in tropical countries na atin

like the Philippines, the movement

syempre of the ITZ affects our seasons.

Okay. So, we experience this thing two

seasons lang naman. Wet and dry seasons.

Ano, if the ITCZ stays too long, okay,

pag nag-stay siya too long in one area,

okay, magkakaroon diyan ng severe

weather disruptions. Okay? Magkakaroon

ng severe weather disruptions talaga,

okay? Or possible may mga storms,

madaming storms yung mabuo diyan. Okay.

At yung ating ITZ sometimes tinatawag

din siya na DU drums. Ano ba yung DL

drums? Okay. In in other references ang

meaning ng dull drums D O L D R U N S.

Ang meaning niya is yyung area of a very

width because the air is mostly rising.

Okay? Very calm wind. Kasi 'yung air nga

is nagra-rice. Bakit po nag-rise 'yung

wind or tumaas? Because 'yung northern

and southern ah wind or trade winds

converge or met. Okay. So hopefully

nakuha natin yung explanation. Sobrang

haba. Ayan. So next yan. So before tayo

mag-proceed, panoorin natin iyung video

about intertropical convergence zone.

Okay? So the intertropical convergence

zone or also known as the ITCZ air

becomes more ayan humit okay during this

time and boyant nagiging magaan causing

it to rise ano due to the combination of

warm tropical waters and intense

sunheat. So by joining forces the trade

winds help elevate the buant air which

sets off a chain of thunderstorms. As

the air rises ba sabi as the air rises

it expands. Ano yung nag-expand? Yung

mga molecules and it cools. Okay? It

cools down the whole region releasing

stored moisture. Okay? Unlike the

typical cold and warm season found in

the higher latitudes, the seasonal

movement of the ITCZ results in changes

in rainfall. in many tropical countries

giving rice to distinct wet and dry

seasons. Ito yung main reason kung bakit

two season lang din yung ating

nae-experience. Okay? A unique to

tropical regions. So severe weather

disruptions may arise from extended

movements within the ITC. Okay. So

tatandaan natin.

So next we have low pressure area. Okay.

So what is a low pressure area? An area

with meteorological characteristics such

as cloud cover, precipitation,

temperature and wind that is

characterized by lower air pressure than

the surrounding area. Okay. So dito sa

atin yan tingnan natin low pressure

area. 'Di ba sa low pressure area, sabi

ko sa inyo mga anak kanina, okay? The

air rises up and then the molecules will

expand causing the regions to become

cooler. Pag naging cool, nakaka-create

na ng mga bands of clouds, yan na

sunod-sunod na. 'ag may bands of clouds

na, may mga group of clouds na,

makaka-create na tayo ng mga

thunderstorms or even r. Okay? So

hopefully is nakakasunod tayo. Ano?

Ayan. Okay. So dito sa low pressure area

na there is a convection or heat

transfer through fluids. Okay? Like air

and the water. Okay? So hot air becomes

less dense causing ito rice kaya

nagiging less dense, nagiging buant,

magaan causing it rice. Okay? So cooler

air sinks and this creates the

convection current. Okay. So an LPA is

an area or low pressure area is an area

where the air pressure is lower than its

surroundings. Okay? Kaya naging cooler

eh. When air converge into the LPA,

okay, it rises, okay? Or cools and forms

clouds. This leads to rain or tenter

storms like what I'm explaining earlier.

Okay. So, an LPA can intensify into a

tropical depression. Pwede siyang

ma-intensify. May mga level agag meron

na tayong LPA or low pressure area,

pwede siyang ma-intensify mga anak.

Okay? Or mag kung let's say what do you

mean? How can I explain the word

intensify? Pwede siyang mag-level up,

okay? Kumbaga pwede siyang magmature,

okay? Like for example, from low

pressure area, pwede siyang maging

tropical depression, tropical storm

until such time na maging typhoon siya,

maging super typon or worst. Okay? Yun

yung pinaka-stages na yon. Okay? Kaya

nga pag may low pressure area, laging

binabantayan ng pag-asa kasi nandiyan

na. Okay, possible may ma-create, okay,

na bagyo. Okay. So, convection is a mode

of heat transfer that occures in fluids.

Tatandaan natin, it allows hot fluids to

be less dense, okay? Causing the fluid

to rise, making the cool air sink. Okay,

this is called the current or the

convection current. Okay. So 'ag mayong

convection current, okay, it makes 'di

ba sabi diyan? It makes or uh allows hot

fluids, hot fluids, hot fluids to be

less dense yung hot fluid magiging less

dense causing it okay and then yung sa

taas ng mga cool air making the cool air

sink. Okay? Yung process or yung

pag-ikot na yon ng cool and warm air is

conduction correct.

So in terms of LPA it is an area with

meteorological characteristics such as

cloud cover, precipitation temperature

and wind that is characterized by lower

air pressure than the surrounding area.

The air r ris rises cools and forms

cloud as it converges into the LPA which

causes rain or storms to form. Okay. To

form. The LPA has the potential to

intensify into many weather systems such

as storms or tropical cyclopes. Kumbaga

ito 'yung summary nung ating discussion.

So next, you can watch a video, okay,

about low pressure area and how it

affects yung mga aviation um aviation

ah what do you call this? Yung aviation

yung sa mga ano paano ba nakakaapekto

yung low pressure era sa aviation.

Ah yung sa mga airplane okay kung paano

ba sila paano ba nagkakaroon ng

tinitingnan din ng mga pilot kung saan

okay yung high and low pressure area at

yun yung mga iiwasan nila kasi pag

possible agag hindi nila yan na-track

kung saan yung may low pressure area at

sila ay nakadaan doon okay nakadaan yung

ating mga planes or airplane possible

maka-cause yun ng turbulence okay which

ah possible accidents, okay, or

magkaroon ng mga crash or worse. Okay?

So yun lang po kung paano nakakaapekto

itong low pressure area sa aviation

process. Okay. So next,

exploring the types of tropical

cyclones. Ano ba yung types ng tropical

cyclones? For the objective, students

will identify the different types of

tropical cyclones and discuss their

characteristics and differences, ano.

Okay. So, let's start.

So first is the tropical cyclone. Ito po

according to pag-asa yung ni-release

nila. Okay. Kung gaano ka lakas yung

kanila or speed nung hangin. Okay. First

stages. Okay. Pag may LPA tayo mga anak

at ito ay nag-intensify, pwede siyang

magka-create ng tropical cyclone. Okay?

Ano ba yung tropical cyclone?

The general term for a storm system that

forms overwarm or tropical oceans. It

include tropical depression, tropical

storm, and typhoon. So tandaan natin mga

anak. Okay. Mayon po tayong iba't ibang

type ng tropical cyclone depending on

the area or location. Okay? So,

hurricane ang tawag natin if yung ating

tropical cyclone ay nag-originate sa

Atlantic at Northeast Pacific Ocean.

Okay. So the term used for tropical

cyclone here is hurricade. Pag yung atin

namang tropical cyclone ay na-form in

South Pacific and Indian Oceans, the

term used for tropical cyclone is just a

word cyclone. Pero pag ang tropical

cyclone ay na-form in Western Pacific,

the term used for tropical cyclone is

typon. like what we are using here in

the Philippines. Kasi nga iyung mga

tropical cyclone na nafo-form sa

nafo-form ay sa Western Pacific. Kaya

yung term natin ay typon. Sa US

Hurricane ang kanilang term kasi nabuo

yung tropical cyclone sa Atlantic at

Northeast Pacific. Okay? Sige. So

classification of tropical cyclones by

wind strength and it is according to

Pag-asa naman.

Okay. So, decode, the number. Okay. So,

what is the answer here? A tropical

cyclone with maximum sustain winds of up

to 61 km/h.

Okay, it's a tropical depression. Ag

yung ating sustained winds is up to 61

km/h, it's a tropical depression. This

is the first stage where iyung LPA natin

mga anak, ay nag-intensify.

Okay? Kumbaga nag naglevel up siya.

Okay. Naging tropical depression na.

Okay. So yan. Naku, nakakatakot na 'yan.

Delikado na bakaform siyang typon. Ano

sir ang tropical depression ba possible

malusaw? Possible naman k malusaw siya

especially kung walang enough or yung

conditions is hindi na met ano. Okay

after this tropical depression kung siya

ay nag-intensify pa okay it can level

up. Okay? A tropical cyclone with

maximum wind speed of 62 to 88 km/h.

It is known as tropical store. Okay,

tumaas na yung kanyang wind speed naging

62 to 88 km/h. And then let's say

nag-intensify pa siya. Okay. A stronger

tropical cyclone with maximum sustained

winds of 89 to 117 km/h. Tatawagin natin

siyang sever tropical storm or STS.

Okay? Pero pag nag-intensify pa to, ayan

na buo na. Okay. A mature tropical

cyclone with maximum sustained winds of

118 to 184 km/h.

It's a typhoon. Okay. Yan na maging

typon na. Okay. And then let's say yung

typon nag-intensify pa. Super intensify.

Okay. The most intense tropical cyclone

with maximum sustained winds of 185 km

perhour or higher. Okay? So it's super

typon. 'Yung ibang mga books, it's 200

km/h yung kanilang nakalagay ng super

typon na 'to. Okay? At ngayong taon may

mga super typon na pumasok sa Pilipinas.

Okay? So nakakatakot ano? Ayan. So those

are the classification of tropical

cyclones. Okay.

Ayan. So for our activity number four,

observing the Philippine area of

responsibility. Students will examine

the Philippine area of responsibility

and answer guide questions to understand

its role in tracking tropical cyclone.

Okay? Ano naman yung ating ano dito? So

the Philippine area of responsibility

okay or par is a designated region in

Western Pacific where the Philippine

atmospheric geophysical and astronomical

services administration. Okay? Or

pagasam monitors weather disturbances

like tropical depression, storms and

typhoons. So here mga anak, yung ating

par or yung Philippine area of

responsibility, ito yung area kung saan

nagmo-monitor yung pag-asa. Tandaan

natin na yung par is iba yan doon sa ah

what do you call this? Anong tawag natin

doun? Sa ah boundaries, okay? Or area ng

Philippines kung saan yung sakop niya.

Ang Philippine area of responsibility is

for ano lamang to for weather

observations. Tatandaan natin monitors

weather disturbances lamang.

So what can you say about the

geographical location of the

Philippines? What can you say location

ng Philippines? It is surrounded by

oceans and lies near the Pacific. Kaya

nga tayo is prone to typhoon kasi tayo

surrounded by oceans. And remember that

typhoons is formed in the oceans because

ocean is the main source of energy for

typons. Tandaan natin mga anak, pag ang

bagyo ay nasa tubig, malakas siya. But

once the typon landed or it make a land

pole in a land or in a continent, okay,

the typon will weaken. Kaya nga during

the times when na typon reaches Shar

Madre, it weaken kasi lumalayo siya sa

source of energy niya which is water.

Pero pag umano ulit siya sa tubig, okay,

pwedeng maka-regain siya ng strength,

okay? Or lakas ulit. Okay? Basta yung

mga landforms, it can awaken a typon. So

what environmental phenomena can be

associated with the location of the

Philippines?

So answer typhoons, earthquakes and

volcanic eruption. So ito yyung mga

environmental phenomena na associated sa

location natin. Okay? Typhons, which is

our topic and earthquakes and volcanic

eruptions because we are um or we are we

belong to Pacific Ring of fire. Okay.

Next. What are the effects of this

phenomena on Filipinas? Ano ba yung

epekto sa atin? Damage to houses, loss

of lives, and floods. Okay. So ito yung

common ano. So hopefully naman kaya

maayos na yung mga sistema especially sa

flood control. Charing. Okay. So what do

you think are the conditions? Why we

experience this phenomena? Ano iyung mga

conditions? Okay? Because the

Philippines is near the Pacific Ocean or

Ty's form. Ito yung pinaka

reason kung bakit na-experience natin

yung mga um what you call this phenomena

na yon. Okay? So especially typon. So

for activity number five, the highlight

conditions for typon formation. Students

will identify and discuss the different

conditions needed for a typhoon to form.

Ano ba yung conditions or kailangan

natin para mabuo ang isang bagyo?

So pwede nating panoorin muna itong

video bago tayo mag-proceed.

Okay. So condition to form a typon.

Okay. So of course okay this one, this

part okay the center is the eye. Okay.

This one. Okay. Um the part where it

surrounds the eye. Okay? It's the eye

wall. Kumbaga ito yung uh wind. Okay na

pumapalibot doun sa ey sa gitna and in

the eye wall okay the air is strong

kumbaga ito yung napakalakas kasi ano po

ba ang eye yung eye ng bagyo is the calm

part of kumbaga calm part okay kalmado

tril pero yung ey niya yung nakapaligid

yun yung pinakamalakas

okay malakas iyung ah hangin okay and

then we also have okay feather rain

bands Okay. Meron tayong mga ah inner

and outer raid bands. Okay. This one is

cooling condensing air. Nasa baba is

warm air that rises. Okay. When the warm

air rises, okay, to a low pressure area.

Okay. Kasi nga naging buant iy warm air

na iyan. Okay? It will rise and then

when the air rises, the molecules will

expand and cool, okay? Causing the

regions to ah form clouds, okay, and

tender storms. Okay. So, next.

So, ito yyung mga conditions para

makaform tayo ng typhoon or bagyo. First

is tropical location. Dapat nasa 5° to

20° latitude. Okay? Tandaan natin,

typhoons usually form in this warm ocean

zones. Okay? Tatandaan natin yan ang

pinaka region, okay? Kung saan yung

ating bagyo ay posible lamang mabuo.

Okay? Kaya nga wala pong mga bagyo doun

sa um ating pols 'di ba? Okay? Kasi nga

hindi niya namet yung ganitong

kondisyon. Okay. So here yan tropical

location.

Next warm sea surface. Dapat yung ah

temperature nung surface or

sea or ocean is nasa 26.5°

or higher. Okay? So warm water gives

energy to the storm. Tatandaan natin

that yun yung pinaka-source niya ng

energy.

Third,

moist air. Okay. Okay. Pag may moist

air, mataas yung humidity, it provides

fuel for clouds and heaving. Okay. Next.

Okay. ITCZ or the intertropical

convergence zone. Trade winds and low

pressure area helps storm start. Okay.

So here sa intertropical convergence

nabanggit naman natin kanina it's when

the trade winds the northern and

southern uh trade winds met or converge

and when they converge it can create low

pressure area because it help the uh air

to rise. Okay? Nagra-rise and when the

air rises, okay, the air or the air

molecules expands and it can create

cooler regions creating a bond of

clouds. will uh certainly okay uh create

thunderstorms okay and many more.

Ayan so sige corolus effect number five

earth's rotation makes the storm spin.

Bakit kaya umiikot po yung ating storm

ano it um Earth rotation makes the storm

spin. Sir, paano po ba 'yung paano ba

'yung paglalakbay ng hangin? Okay

straight dapat 'yan din nga straight.

Okay. Yung paglalakbay or yung travel ng

hangin. Pero sir, bakit doon kanina

parang yung hangin is parang paikot?

Okay. Okay. Dapat straight yon. But

because the earth rotates kasi

nagro-rotate yung ating earth gumagalaw

yung ating air din. Okay? Parang

napapaslant niya. Okay? Ang tawag natin

doon sa parang nag-spin yung air is

corolis effect. Okay? Because bakit

parang nag-spin yung air? It's because

uh the earth rotates. Kung steady po ang

earth hindi gumagalaw, possible straight

yung travel ng air. Okay? Pero dahil nga

nagro-rotate siya, okay, it

create corolis effect. Okay, that helps

the typons uh or storm to spin.

Okay, next, why do you think typons do

not usually form near the equator or 0

degree latitude? Okay? Kasi nga because

there is no corolus effect to make them

spin. Wala namang corolis effect doon.

Okay. Next. How does Ocean water

contribute to the strength of a typon?

Okay, it gives heat and moisture that

power the store. Okay, so proceed tayo

sa formative assessment. Okay, choose

the letter of your answer. In which of

the following layers of the atmosphere

does weather occur? Correct. In the

troposphere.

Next, which of the following is the

generic term for an intense circulating

weather system over tropical seas or

ocean? Correct. It's letter C tropical

cyclone. How is the weather in the eye

of the typhoon described? Ano yung sabi

ko kanina? Okay. It's cal ano? Okay.

Yung violent talaga is nandun sa eywall.

How does the land form affect typhoons?

Paano nga nakaka-affect iyung landform?

Like what I'm talking to Sharad earlier,

it makes the typon more violent. It

disrupts the rotation of the typhoon. It

helps the formation of typhoons or it

does not affect the typhoon at all.

Correct. It's letter B. It disrupts the

rotation of typon. Okay. Para maweaken

yung type natin. What causes tropical

cyclones to spin? Bakit ang spin?

Gravitational pool of the sun,

gravitational pool of the moon,

revolution of the earth around the sun,

or rotation of earth in its axis? Ang

sabi ko kanina, because of rotation of

earth in its axis. Okay? So hopefully

you learn something for our discussion.

So kayo na lang mamans magpahaba kung

meron po kayong idadagdag. Pero I think

mga dapat nating idagdag like for

example yung parts, okay, madi-discuss

naman natin siya in the following weeks.

So no need to be to worry. Okay?

Especially mga storm warning signals,

madi-discuss natin yan in the following

weeks. Okay? So, thank you again and

have a good day. M.
