This has to be the best animation yet - unfortunately I didn't find it until AFTER the test.

Reading about the ENSO cycle in the textbook and having the professor explain how this works still left me confused. I am a very visual learner, and this helped me so much! Thank you!

This is the clearest explanation for this I’ve ever found

"Winds go from east to west", the only thing i understood 😅

El Niño and La Niña are opposite phases of what is known as the El Niño-Southern Oscillation (ENSO) cycle. The ENSO cycle is a scientific term that describes the fluctuations in temperature between the ocean and atmosphere in the east-central Equatorial Pacific (approximately between the International Date Line and 120 degrees West). La Niña is sometimes referred to as the cold phase of ENSO and El Niño as the warm phase of ENSO. These deviations from normal surface temperatures can have large-scale impacts not only on ocean processes, but also on global weather and climate. El Niño and La Niña episodes typically last nine to 12 months, but some prolonged events may last for years. While their frequency can be quite irregular, El Niño and La Niña events occur on average every two to seven years. Typically, El Niño occurs more frequently than La Niña.

What a beautifully explained video. Thank you ❤

This phenomenon occurs every three to four years and its effects on the climate through their influence on several factors and the interaction of the atmosphere with the ocean include El Nino and through their impact on trade winds seasonal increase or lower depends on this phenomenon, thanks to this video we have learned a lot from him

Awesome video. Thanks for posting. Keep posting these edutainment videos

Thanks so much, I needed this for research

very nice description of El-Nino and undersandable too in a simple way

Spot on ! A splendid explanation !! Thank you.

this is incredibly helpful video! thank you so much

Thank you for that information. We are also camping next week in Cornwall so to know a weather professional is braving it also is a huge comfort. Roll on less loops!!

This was great! Thank you so much. Now I feel like I really have a better grasp on both concepts of this weather phenomenon. I’ve subscribed to your channel and will visit regularly for more lessons. Excellent work.

Best ever vid talking about el nino this is even better than national geographic keep up the good work

Thanks for explaining

This is amazing thank you so much

very informative video! thank you so much!!

Good modeling. Thanks for sharing.

This was so helpful thanks so much, you do a much better job at explaining than any textbook I’ve read

What a amazing work you are great gentleman

This help me alot.. I got the concept so finely for my finals exams... Thanks sir ❤️

very illustrative, thank you.

Fantastic explanation.

The video helps me understand more about the El Niño

Very concise and simple explanation, essentials captured ! Awesome. Thanks MetOffice !

Thank you for this very informative video. Climate & weather is very complex so grasping various topics can often be difficult. It seems it's actually atmospheric conditions that triggers both El Nino & La Nina. Sooo, how will the climate breakdown and the broken jet stream (north & south) affect these phenomena? Both El Nino & La Nina are confirmed by the status of sea-surface temps in the Pacific, but could both these events be predicted by the current state of the jet stream, or are the impacts of the jet stream too localised to impact global ocean temps? There is also the Indian Ocean & Atlantic Dipoles. I assume each of these phenomena have a knock-on effect on each other? Which has the strongest influence?

great video! it was helpful. thanks a lot

thank you for the video! now i can visualize this phenomenon much easily thank you:))

El nino is a weather phenomena which has global character, it is a system that involves hydrological cycles, what you saw was not volcano but representation of warm waters, awesome video thankyou met.

I’m so sleepy. I couldn’t understand a single thing.

This pushes the warmest water to the far westem part of the tropical pacific ,Thank you very useful

Helped me finish my science project. Thanks, Met Office!

Super helpful! Thanks! :)

They also effect the activity of tropical cyclones in different oceans. It creates a more favorable environment for tropical cyclone development in the eastern Pacific and some other areas, and less active in the northern Atlantic. It is or almost the opposite with a La Nina.

Thank you for this beautiful video

I am enlightened. Thank you so much

Video more than wonderful .. explains the phenomenon simplified manner and understandable

2018 South Africa. i have an essay on this for my exam and this video has helped me so much.

really helpful...understood much of it

i liked this precisely way to explain the el nino phenomena ..its really important to know more about it because its in touch with important effects in our life like floods and drought..actually i didnt know about this phenomena before!!

very very useful

Excellent synopsis of complicated phenomena! Thank you.

beautifully explained, thanks

Thnk you very much.

Amazing background music!

Amazing animation and explanation... Awesome🙂👍🏻

Wonderful explanation

video more than wonderful; explain la Nino also impacts global weather

Thank you. It's very useful

What a good expline to this phenomena , thnx

Hey! My name is ElNino and my Sisters name is LaNina! She does the same thing that I do, just a lot more extreme, so, I form, by atmospheric pressure in the eastern pacific, when this happens, easterlies weaken, then, upwelling stops, several circulation cells form, and then air rises over the eastern pacific, and then subsides over Australia and Indonesia 🇮🇩 I memorize that for my exam tom 😄🙈 how do you think I did?

Thank you for sharing this video tutorial

Superb explanation 👌 Superb animation👌 Thanks a ton.💟

thanks for the video it helps alot for my test

Learning geography with you is fun...put more concepts on geography and environment...!

fantastic video! thank you!

so proud and happy with all explanation from met office. btw, can u help me explain about what is monsoon? what's the impact for the rainfall and how does it work? how about the variability and interaction with another phenomena? and can u help me to explain about the predictability of monsoon? Monsoon is very interesting I think, but I wish u all could give me a little explanation with your awesome video. waiting for it. best regards from me and thankyou so much met office. :)

sir your video clears basic doubts of el lino

Nice video, very impactful

Great Explanation!!😊

That's a great video...good explanation.

you're AMAZING THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!

Can you tell me what is general temperature difference between hot spot and cold spot . . . Just for having clear picture

Just read a chapter about this in my oceanography class, this video just made it all clear for me thanks!

who here from school hehe

El Nino is big climatic phenomena that prove how energy transfer between ocean and atmosphere

El Nino is impacting Indonesia this August

This was so helpful

Best explained

Can you please explain Ekman Transport in relation with El nino. What and how things happen at Peruvian Coast? Trade winds move from East to West, so due the Ekman transport. water beneath should move 90 degrees to the direction of the wind. But when we see the El Nino explanation, it says, Trade wind leads to piling up of warm water in Northern Australia and UPWELLING takes place at Peruvian Coast. I am confused, where is Ekman Transport when trade winds are moving the ocean current in their direction only leading to accumulation of hot water in N Australia. Please help.

gr8 work . keep it up .

Is there a difference in the impact of the phenomenon on the global weather when it occurs in 1. Temperature is above average by one degree 2. Temperature is above average by more than two degree

Very useful video.

How is the formation of warm water there on pacific it's not clear can you please explain?

wow! Chile's beaches at no much distance from each other but with have water with very different temperatures. Now I understand why!

This is so cool

This phenomena shows the relationship between atmosphere and oceans so we think this phenomena very good to make changes on the climate

This video helped me to understand the formation of rainy clouds

very well explained

thanks for explaining this so well. my teacher tried explaining it to my class several times but i just couldnt get it, so yay thanks met office!!!

My humble request, sir plzz provide us a video on Indian monsoon plzzzz😁😁

I love being a meteorologist. there's always something "wowing" to learn and it keeps you humble because you realize how much you CAN't control when most of the world is desperately trying to control and own everything and everyone else.

Thanks for helping with my assignment

Hello, my names NINOOO

Literally the most helpful video I've ever watched😂

Can you make a video on all the things happening in the stratosphere and how it affects the tropospheric weather regimes

Whats the difference between easterly and trade winds?

So good

Thanks met office..good work!👍👍

Correct me if i am wrong , when he was explaining the normal conditions. Did he make a mistake by saying that the warm water piles up at north and south america when it should be asia and australia instead because the pacific ocean lies on the left of North and south america and the wind is moving from east to west.

Sir we know the air rises from the equatorial low and subsides in the sub tropical high so how the air is rising from the central pacific and subsiding at almost the same latitude at peru ?

Wonderful 🤘🤘🤟😘😘

Fab video!

thank you this was helpful

You have explained El Nino well. But some viewers get confused because of the way you presented it. Initially you are explaining normal phenomenon ( which is similar to La Nina) . Later you are explaining El Nino ( but didn't explicitly mention " El Nino ").

Thank you for have this video it is good to study El Nino.

so basically, usually the warm water eventually causes rainfall around indonesia and australia and upwelling around the northwest part of south america. but when el nino happens the warm water doesn't have enough strength and stops in the middle of australia and south america and since it doesn't reach australia and indonesia there's not enough rainwater for them which causes droughts in indonesia. usually the rain falls on the western side of the pacific ocean but during el nino the rain ends up falling on the more eastern side, causing peru to be flooded. also I'd like to note el nino occurs around christmas and it's summer time in the southern half of the world during christmas. so el nino occurs during summer. on the contrary, when la nina happens the warm water goes too far into indonesia and australia which causes more than the usual amount of cold water to go towards south america. now does this mean la nina causes floods around indonesia and australia and droughts around northwest part of south america?

Why isn't the video encoded in 1080P?
