I was searching all over the internet trying to find the differences between Environmental Lapse Rate, Dry Adiabatic Lapse Rate & Saturated Adiabatic Lapse Rate and couldn't find anything. This video helped explain all of them. Thanks a ton!
I know I'm late to the party, but I just wanted to thank you for your clear explanations - finally I also (not what I was here for) understand the formations of the Föhn winds from the dry/wet rates. Thank you!
I have searched a lot vedio lectures on atmospheric stability. yours explanation is crystal clear. Thanks for clearing my doubts through animated slides and lucid explainations.

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 am thankful to you,,for this explanation,,it help to understand me about,, Climatology,,,how air get warmed while decends down the leeward slope due to adiabatic process.
Basically temperature is defined as average kinetic energy of molecules. Air at sea level is compressed compared to air at higher elevations. So Air at seal level have higher KE and the temperature is higher than temperature at higher elevation not necessarily because of the heat of the sun, but because of the increase in KE from air pressure on the ground. No heat is added from sun but, the average KE is higher from the increase in pressure at the sea level, so the heating is adiabatic. By the same resining The when air moves along the mountain upward and faces lower air pressure at higher elevations and average velocity or KE drops and air cools down due to adiabatic cooling at higher elevations.
Your video is how I was taught BTW: Higher pressure has more kinetic energy therefore lower pressure will take the easiest path out/around. If you have something blocking ocean currents from forming for long periods of time you get 'higher' pressure over that blockage resulting in low pressure systems going the easiest path around. Models however don't take ocean currents into account, so you get all sorts of silly scenarios show up.

Thank you for such a well-explained presentation. This video helped me towards becoming a better student pilot. I have a question. If you know the answer to it, I would be very thankful if you answered. Are the dry adiabatic lapse rate of 10C/1000m and the wet adiabatic lapse rate of 0.6C/1000m only true for ISA (International standard atmosphere) conditions?
What we've been seeing in the Pacific is long term blockage (Likely the Great Pacific Garbage High) keeping the storm track going up into Canada and dive on down into the Midwest/East Coast leading them cool/wet and the west warm/dry. Models do not take any of this into account BTW: This is my personal observations over long term.
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.
1.Air expands when heated and contracts when cooled. 2. When air is heated, it expands and rises up since the surrounding atmosphere is denser. When it goes up, the air cools and contracts and water vapor condenses to form water which is eventually attracted by gravity as rainfall/snowfall. But in adiabatic expansion, we have seen that air expands adiabatically as it moves upwards. If it expands, how is it not able to hold the moisture since its capacity has now increased? And why does rainfall occur? Can someone explain?
Thought Loop: Compressing a gas causes a greater number of molecules at a given average velocity to occupy a smaller space...so there will be more molecules slamming into the mercury in your thermometer in a given span of time...therefore hotter. How can compressing air speed up the little balls involved in elastic collisions? Momentum is preserved in every collision...so average velocity (temperature) cannot change. The gas molecules can only move faster by adding energy. It requires energy to compress a gas.

Thank you. You helped me put scattered information together to make much better sense of the subject.
I am glad to hear that, Debbie.
You are a HERO, Finally, someone puts this difficult subject into a understandable from.
Thank you, Ton. Glad you like it.
Clear and consise. sometimes reading concepts can be hard, but with graphics and clear language you've explained it brilliantly. danke!
You sir, are a gentleman and a scholar. Thank you!
As a Paraglider your very good explanation will help me fly better. Excellent video.
This is the best explanation I have seen, yet. Very clear and very well explained. Thank you, for this!
I come here because I don't understand Adiabatic lapse rate. This actually helps me a lot, thanks!
This really helped me. I was reading my geo textbook and felt so lost. Now it all makes sense.
Terrific, Justin. I am glad to hear that.
Now I can confirm the adiabatic lapse rate is relative to the air pressure! Thanks a lot!!
Your channel had been super helpful. Going to the exam now feeling a lot more comfortable with this topic. Thanks

thank you so much I did not understand this at all until watching this video!
Thank you for your kind comment, Emily. I am glad that you found the video helpful.

Thanx alot.U explained it in an easy language without taking much time ,i cud finally understand this topic after searching alot .

that's per 1000 ft , " note that 1000 ft = 300 m "
Thank you for the great explanation!
still very good contect - thank you!
