Thank you so much
thanks i love u
Sir ur videos are full of precise & very useful information
Can you explain why trade winds reverse before an el nino event? Since trade winds are caused by the coriolis force, how can they reverse?
Explained lucidly🙌🏻
Thank you Stefan! Now I finally understand thanks to you!
Superb lecture. So easy to understand. As professor myself, I have a lot to learn from Prof. Becker.
So clear ! It removed some of my cloudy thinking this is excellent !
I came to this video during preparation for a Sailplane FAA oral exam and checkride. Thank you so much. The content is concise, clear and the illustrations really clarify the material. Best wishes
Great video. I'd like to thank my friend Roisin for keeping me company as I watched it.
Thank you Mr Stefan. These videos are really comprehensive yet precise. Helps building strong conceptual foundation.
If energy is released through condensation, why isn't the process called DIABATIC instead wet adiabatic? Thanks
Incredibly informative! Thank you so much for providing such a well-structured lecture for free! :)
Exactly what I was looking for, been wanting to formalize my meteorological understanding for a long time. I may consider putting together a playlist for you because the lessons are kind of all over the place chronologically.
I fucking hate school. I cant believe I paid money to learn this useless bullshit
This explanation is clear! Thank you!
still very good contect - thank you!
Sir, your video is gold.... May I ask where can we access the simulation you use to explain the stability. Thanks
Yes
Good-day, ?Could you place the chapters into a convenient playlist, thks in advance.?
Answer to Question 11a - Take a surface temperature of 92 degrees at low levels with a dew point of 73F. It is 2pm - time of peak insolation heating. The high dew point and the surface heating will allow the air parcel to eventually break convective inhibitions in the surface-based environment, discourage sinking, and allow a lapse rate to go up to 7C to 8C per km, which will eventually lead to an air mass thunderstorm, which is the final product of atmospheric instability. Answer to Question 11b - Take a surface temperature of 75 degrees, with a dew point of only 50 degrees. There is full insolation, but with the low dew point reading, the lapse rate will be roughly only 3C to only 4C (maybe 5C per centimeter), and this low level dewpoint means the sinking of air - or subsidence - is very, very strong. Even if there is a moist adiabatic rate that can cause cumulus clouds at the LCL, the low lapse rates will not allow the cumulus to grow any further into thunderstorms. So this is called fair weather cumulus, and this subsidence and low dew points will mean fair or good weather, which will mean the atmosphere is now stable, thanks to the lower lapse rate.
Sinking air is known as subsidence.
Thank u sir It is very nice and helpful vedeo .
Please let us your email
Can i contact you please
I can't believe this is still helpful after 6years ago, THANK YOU SIR
Clear and consise. sometimes reading concepts can be hard, but with graphics and clear language you've explained it brilliantly. danke!
Very nice explanation love from india❤
Been there in 1995, some changes in between I saw....
Thank you so much! This helped me understand
I'd love to see the rest of the videos that are missing!
Thanks "pull it upward" at 9:44 S.B. "push it upward". A huge version of the effect at 6:57 is the desert zones nominally latitudes around 30S & 30N. It rises wet from warm ocean in the ITCZ and cools at the moist rate, heads towards Poles, gets turned west--->east by Coriolis Effect and then descends warming at the dry rate with the water latent heat having warmed it on the way up & hot dry air at the surface results, deserts.
I owe you lots of beers. Thank you.
Very clearly explained. Thanks!
I understand that when air rises, pressure decreases, volume increases, and temperature decreases through adiabatic cooling. However, I've also been told that cool air contracts like warm air expands. How does that work- wouldn't these two facts balance each other out and the air wouldn't move at all?? Obviously it works out that cold air rises because if I go climb a mountain it will be chillier at the top. But cold air is also more dense than warm air, so how is it higher and how is this true? I feel like adiabatic processes are true to the world but somehow go against those other facts I know.
you are so underrated...this is knowledge instead of youtubeknowledge:)
prof Dane Wigington expleins some important details to have a clear idea
What book is this video referring to?
Finally!!! a clear explanation. Tried wikipedia, and as usual the explanation was written for a postdoc in thermodynamics.
So clouds form because the water vapor expands to contract into liquid. Got it 😵💫
I think i just self diagnosed ADD. I keep thinking a diabatic process is when you eat candy and chips and an adiabatic process is when you eat vegetables. I know this is not what he's talking about but my brain doesn't.
Chinese invasion. Beside that, lovely video with good info and scenery
This was informative with good figures to explain these complex processes.
12/13/2022, weather pattern matches this video *exactly*
this very helpful to me thx
These videos are really helpful! Thank you so much Stefan! ^^
How do we know when it changed from dry adiabatic rate to wet adiabatic rate? i.e. how do we know that happened at 3000 m? How do we calculate that?
Thanx alot.U explained it in an easy language without taking much time ,i cud finally understand this topic after searching alot .
it is a very very helpful lacture in short time
Cool, Louisiana.
