- In this series, it tells us how the air pressure work in our environment.
At first glance, air appears to have no power. However, air influences our lives in many ways, and causes various meteorological phenomena. Snow, rain and wind are just some of the phenomena created by wind. These weather patterns vary depending on the pressure of the air. Air is all around us. It is difficult to tell since it has no color and no smell, but air varies in temperature and humidity. A large body of air with the same temperature and humidity throughout is called an ‘air mass.’
Places with higher air pressure than the surrounding areas are marked High (H), and areas of low pressure are marked Low (L). The movement of air from high pressure to low pressure is called ‘wind.’ The direction and characteristics of the wind that blows in areas of low pressure and high pressure are different. Around low pressure areas, rising air currents form, and around high air pressure areas, falling air currents form. In low pressure areas, moisture-laden air rises up and forms clouds, resulting in cloudy, rainy, or snowy weather. And around high pressure areas, the air descends, making it difficult for clouds to form. This results in clear weather.
Let's take a closer look at the air pressure story!

At 4:50 it is all you have to know for understanding the link between barometric pressure and weather behaviour. After tons of research in this video less than a minute made me understand all.
"Air seems powerless"
Our lungs: Am I A Joke To You?
ha ha ha
ha ha ha
i just wanted to know what a LOW PRESSURE AREA is... 5 minutes in im confused.
Yehhhh sammeeee
Still want to know? Lol I can help
A low pressure area is a warm air mass where air particles are farther apart than normal.
@@okand-1124 HELP.
Depression - The sun heats up both land and sea. At sea, it creates a high pressure area which means cooler air is collected. Land on the other hand has warmer and dry aair so to balance these areas out the sea replaces the land’s low pressure area with the cooler air. This creates a depression.
The sun heats up both land and sea. At sea, it creates a LOW pressure area and NOT a High pressure area.
(Tryin to figure that out causes me depression too)
That gave a high pressure in my head🥴
I’m here because of my curiosity. Just sat and randomly wondered about these.
Same. My question was how does the cold affect the air tho.. ig the question it self don’t even make since after watching this video
Same
you and me both.
@@itsurboidonnie You Are Not Alone B
no problem with feeding the brain
We don't call cyclones willy-willies in Australia. They are just cyclones. A willy-Willy is a small vortex of wind that picks up dust for a short time. Blink and you will miss it.
Amazing video. Such a great video to watch before teaching about air pressure and air masses!
This video actually really helped me for my global understanding on meteorology for my ATPL exam. Thank you very much!
me too
actually really very
Nah
didn't you mean to say, "your global understanding on melancholy?" 《:~\
Now i saw this, i cant stop wondering what kind of air, pressure, clouds above me. Curiosity hit me so hard.
Who else is here cause school assignments 😂💔
Who isn’t?
YT_TGC Works meeeeeeee
Trust
phục êwê too late..btw was investigating and go do your hw
Meeeeeee
This video is so simple yet so Educational... Good work! 👍
HI class watching this currently in science class because our teacher sent us the liiiinnnkkk.
@Caitlin Rohde loll
This is the most informative meteorological video I've seen on RUclips, damn.
This video explains everything 👍🏽
Hang on how is the cold front going in the same direction as the warm front when both arrows are in opposite?!
I have an RYA exam tomorrow and this finally makes it make sense 😂 Thank you!
I'm just here because I want to learn how to use a barometer, this was very informative.
Nice....
THIS VIDEO IS AMAZIN
Choosing to color the high pressure area red and the low pressure area blue is so counterintuitive to my brain, and made these concepts more difficult to understand. I associate the color red with heat and the color blue with cold. I have to constantly pause and remind myself that the red H is a COLD area where the air particles are more compact, and the blue L is a HOT area where the air particles are farther apart. If they made the red H the hot area, and the blue L the cold area, then I wouldn't have had to watch this 3 times to understand what is going on.
I've always taught H is blue and L is red to my students in America. In this video they change it up part way through. Isn't that a mistake?
The H should have been blue and the L should have been red. Because low pressure occurs when it's warm and vice versa. That's my only critique of the video! Great work
very useful for those who are studying meteorology subject for ATPL exams
thank you sooo much this willl help me for my test😄☺
never been more confused

Im here cause i love science!❤
you are a nerd
mhh !! the weatherman is going to make more sense now
Fyi... typhoons spin in a counter clockwise fashion in the northern hemisphere not in a clockwise fashion as pictured in the video.
NO,, only 95 percent of them do.
Ah yes, rain and wind are created by...wind.. thanks for the clarification
keep up the good work
9:57 till the end was understandable
Thanks 😊
I’m here cause of school
At 9:04 you said “friction with the ground causes a lot of kinetic energy” instead of “a loss of kinetic energy” as was stated in the subtitles.
I'm having to watch this for middle school and it's like it's talking to elementary kids
I agree I’m in G7
Lol true
IPastelCloudI · yeah cool
i’m a junior and i have to watch this 😭
Gacha Ximena / yea same
Wait, so in a hurricane if the pressure keeps dropping a lot, its a bad sign of catastrophic damages? Is that what you tried to tell us? That part confuses me. Or is it the other way? Pressure increases=super super damage??? Or my first statement?
The lower the pressure the most intense a low can get
Wah achha video bataaya hai
tysm!!
uhm am me supposed to write this down 0-0
MY BRAIN :(
AM VERY CONFUSED I WATCHED IT 2 TIMES OVER
I know im nerdy lol😂
I wouldnt
Same
you should write notes if you want to review but don't want to repeat the video.
Interesting. I just got a weather station that measures pressure. It gives me different options to read the numbers. Wish should I go for..?
High "H" should be blue. Low "L" should be red.
No
There's no color that it 'should be' color doesn't represent a pressure so he can color it whatever he wants
No cuz this isn't related to temperature... High pressure zone can be hot or cold and low pressure zone also.
Yeruchum Dear it is the standards at least in most western countries that H is denoted in blue and L is red for high and low pressure respectively. He is correct.
@@joshuagavaghan224 who maintans these standards?
This one is important lesson on science class
No it is not
Um, what?!
My exact thought
Why is High Pressure H Red and Low Pressure L Blue? That's backwards.
Michael Sheldon High pressure brings sunny weather - sun equals red. Low pressure brings precipitation/rain - rain equals blue. I hope this helps!
I understand that reasoning, but look at any weather map reported by news outlets and you'll see it's backwards. Low pressure is red because it's warmer than surrounding air, warm air rises, that allows for evaporation, which allows for precipitation. If air/water vapor doesn't rise, it can't fall back to earth. H is blue because it's colder than surrounding air, causing it sink, which creates clear weather. I won't even get into the density of warm v. cold molecules in a column of air. Scientifically, L is red and H is blue. Your colors are backwards and lead inaccurate understanding based upon the greater scientific community. It's the main reason I did not use this video with my classes during this time of distance learning.
I am watching this for geography
Good video
I'm even more confused now. Information overload. 😆
Thought my geography teacher was bad
Oh No no ikr
I mean mine in worse...
who else here is for a school assignment?
I all ways subs to you
Asynchronous assignment from Malaysia
Explaining whole Meteorology course in 10 mins vid
I’m here in quarantine dose get boring
Atmospheric pressure increases sound decreases, motion sickness?
Who else is here cause of hot weather in Seattle?
Uh I have to write a paragraph about this. Can someone give me a quick summary 😭
no
I feel so bad for you. We are learning about whether and my teacher assigned this vidio to watch.
@Joshua Liu if you were in her place you would also probably want help.
no, do it yourself. It's better doing it yourself
Who's doing science work
i found out that my phone actually has a barometer installed and now i'm learning about this so i can predict the weather in the short term
Me watching this for school
I have a practice STAAR tomorrow so thx
which was smooth invisible vaporization
The voice over sounds like the one from AbsCbn advertisement... LoL...Anyway, this documentary is very informative. I thought I was watching SineSkwela in English version hahahaha (90's kids in PH knows this well!)
tnginamo
Yes here to help my 11 year with her science homework 🙊
Watching this right now because of a heatwave over the Pacific Northwest
I'm Australian and I've never heard of a cyclone called a willie-willie
Wow
so desert and polar regions both have high pressure done
I have to watch this for school how about you guys
Add879 XD ya same it sucks
Yep I agree
Yep XD
very nice
6.6 class?
@@sneaky_boy3793 ayo?
@@toj8657 hi
whether weather is understandable
k climate is already formed and this air pressure changes it, gud
so low air pressure does not cause rain but it depends where it began right
what
What is cyclone?
Nabaraj Baral *watched a video of ‘whats cyclone’*
I have a question. Using this valuable information, how can a person who is DIYing their own mortgage free 4 story (3 story underground) house create a strong fresh draft of air that cycles through the house?
I’m researching termite mounds to see if it can be done passively but yea.
Watching this video helps a bit but the solution still evades me.
I’m trying to focus on making it an off grid full 4 story house. Must be off grid.
You know what I'm gonna stick with hot wind (high pressure) and cold wind( low pressure)
why you are talking about korea
I think it's because EBS(the channel) is Korean education chanel
Why not? It's as good an example as any. Or does it have to be based on where you are from to be relevant?
Bc it's best and it's a Korean channel
Hol up
My geo teacher thinks I’m gonna watch this lol
There is so much information it's getting me confused.
if wind causes wind, then what causes wind to begin with?
I believe wind is caused by a temperature differential.
wind is caused by temperature differences
First i was curious about wind... Weather.... Now i am confused!
Dude we have a cross word puzzle all about this 😭
Anyways, what grade are you learning this in?
9
Year 8
@@lydiabotros7953 I learned this in 5th 😨
A willy-willy is NOT a cyclone but a whirlwind or dust storm in Australia but a cyclone is called a cyclone like in the Indian Ocean.
“Snow, rain and wind are just some of the phenomena created by wind”
wut
Why don’t fronts form around high pressure systems?
Bruh, did you figure this out lol. I was wondering the same thing
@@YoungChunds not yet unfortunately
Today is my science exam and i'm learning this 😅
Hey are you from South Korea or north Korea.
At 3:27 Shé gotten Every-Thing back to fronts.
Air presshuré DROPS on coldé front, NOT RISÉ
i dont even gwt this and jm jn gojng to go
Of course Australia calls it a Willy-Willy
A willy willy is a tiny tornado.
I want to know how warm air leads to low pressure area
no, warm air is less dense and it moves up so it causes low air pressure but if the land near u is also is warm then the area where u are still being has high pressure just my point of view but really we all need to understand more about climate
@@syedmuhamedbasheers4959 thanks brother😊😊😊
Dude your just talking about Air masses. I came here to learn about Air PRESSURE
Omg I can’t even start at how many wrong things there are. A tropical depression is the EARLIEST stage of a tropical cyclone, so don’t call it a typhoon. Every area of formation for tropical cyclones was wrong. The Australian and South Pacific areas you said are not even close to where they form, the area u showed “Willy-willies” is an area that has probably seen less than 10 tropical cyclones in earths history. Not to mention how far south you indicated they form (New Zealand really ? water temps barely scrape 70, not to mention interference like wind shear. Then for the height of a “tropical depression” ( I cannot get over that) you just stick up a picture of a tornado. Seriously rethink your information
They are not called Willy-Willy anymore. The weather bureau calls them tropical cyclone.
Thanks for pointing out the misinformation! Guess l have to find another video to study from😅
🤯😵
My feelings exactly ☠️
My brain hurts
" air has not color and no smell "
Then how do you smell and sometimes feel farts?
There are chemical substance in farts which makes it smells
@@choppy2505 I'm lactose intolerant so I'm constantly gassy
Why Korea make your example?
It is helpful , Yet I wanna get example with the Indian perspective
just here because school Lol
ERROR: "Korea" is not a country in Asia, there are two separate countries, "North Korea" and "South Korea."
It depend Panama channel
School is starting to piss me off
