Chapter 11 Atmospheric Stability

[@alecpanayotov]

I'm a student pilot and I've always struggled understanding lapse rates, this video is outstandingly clear in its explanation. Thank you, I finally understand!

[@stephaniemartinez5062]

The duration of this video is about 13mins yet I have been pausing and replaying and rewinding for abour an hour and a half to understand. This is very helpful!! I appreciate it, weather is difficult for me and this concept is hard for me to grasp and I feel like its a must when trying to interpet Skew-T

[@harshittyagi3394]

This video, I tell you, is a hidden gem. You, Sir, have crystal clear concepts and the ability to explain in that same way.

[@senasenasal]

When i become a airline pilot, i will come to see you and thank you :))))

[@mrapollo13]

This was significantly more clear than my lectures notes. Thanks

[@monamidutta8016]

Its really helpfull. I have studied atmospheric science and learnt all these but after seeing this video it is more clearer than my previous understanding

[@mdkaisharmumtaj6371]

Where condesation take place and why? In satbility or instabilty.

[@hgbugalou]

Thanks for sharing the knowledge! That is one of the single best things one human can do for another.

[@stefanbecker9933]

Thank you, Michael.

[@Festus2022]

This is the best explanation on the internet. Thanks to Stefan

[@Mr.Man-]

Wow. This has been the easiest to understand, compared to other videos and in-class lectures. Thank you!

[@stefanbecker9933]

Thank you, Michael. I am glad that you found it helpful.

[@vladlovin1928]

Doing an ATC course and really needed some things cleared up. Thanks alot :)

[@stefanbecker9933]

Thanks you, Vlad.

[@bluethermal]

thanks for making these videos, they are really helpful in understanding things

[@AllanEvansOfficial]

This was a lot to wrap my head around but I think I got it. I’ll be back to brainwash myself with it again later. Thanks for the great content!

[@k7photography]

Thank you so much, Stefan! You have made this concept very clear .. Love from India. Please make a video on Plume Behaviour.

[@pritampandey3230]

Big Thanks.. for explaining in simple way

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.

This explanation was amazing, thanks a lot

[@jishnagopi]

Great Explanation..Thank You So Much ...

[@RajashreeSahoo-g4g]

Thank u sir It is very nice and helpful vedeo .

[@ahewett93]

Your videos are immensely helpful Mr. Becker. Is this parcel simulation tool available for use?

[@JayantaDas-wt1kb]

It is very important information

[@rajeevkumarsam5499]

Nice lecture.plz make a vedieo of plume behaviour and its type.

[@RDSTUDY08]

Wow marvelous explanation

[@theskyobserver]

Sir, your video is gold.... May I ask where can we access the simulation you use to explain the stability. Thanks

[@udayakumarpv2583]

Nice video, well explained with animations

[@socksisdead4098]

thanks i love u

[@goboksu]

Hi Stefan, this is good! -Woonsup

[@stefanbecker9933]

Thanks so much, Woonsup.

[@thotaradhika8615]

May I know the reason for dry adiabatic lapse rate.. why is it different from the environmental lapse rate??

[@ruancabralexatas6370]

What is the name of this simulator?

[@Jhamad_Environment]

Its absolutely helpfull for me but in one point i still confiuse if an air parcel has same temp with surrounding air can it move upward or it stay at the earth surface

[@mrhuratorhakho631]

Stay at the earth except when there is vertical wind movement.

[@terryfinchguitarist]

Thank you, very helpful

[@thesupermysteries1355]

Very well !!!!

[@SuperAmazingAnt]

Gravity is force, boy what ever is not.

[@nicco8221]

thanks

[@azadmujawar2454]

Thanks so much ......

[@indranilroy6446]

Got it

[@ankitapandey5595]

Hey Stefan Becker , it was very understandable 😀 except conditional stability ...thanku.......cau u make more video on physical geography completely ..plz

[@shishirsrivastava976]

Are you upsc aspirant
