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.

So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠ Quran
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
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.
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.
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.
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.
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?
10a. 10 degree celsius decrease in temperature per 1000 meters increase in altitude 10b. orographic lifting, convection, convergence and frontal lifting
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.
Dear sir, Your videos are very helpful to anyone who wants to know general atmospheric concepts. I request you please make a video on TRADE WINDS INVERSION AND EFFECTS ON HAMAN LIFE IN GENERAL. Please make video on the aforesaid topic. Please sir.
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?
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.
3:35 how does releasing energy decrease the rate of temperature change? Doesn’t cooling of something mean energy is being released? Why wouldn’t this cause an Increase in the rate of change?
If I'm not mistaken, that's because the energy released in the condensation is absorbed by the air parcel. So as it condenses it loses 10 degrees due to adiabatic cooling, but the condensation releases 5 degrees which heats the air parcel, so now it only lost a net amount of 5 degrees.
