Thanks! As a teacher you get the speech thing. Some comments say way too slow but you know how it's different in a class - and depending on what class. Here is an updated version for wider audiences that I made. Cheers! kzbin.info/www/bejne/iZPUep-lfrejq68

Sr., as a science teacher and after having climatology classes in my post grad. I can only say that this is genius level demonstration with analogy + storytelling. I already said sometimes to students "imagine the atmosphere as we are all in a huge close air aquarium", and air pressure columns in a mountain and at sea level as similar to our crushing sensation in the ears as we go more than a couple of meters deep in a pool, but this is the cherry on top of all that analogy cake! 😂👏 Definitely subbed 👍

[@christopherdever5536]

Yes! My understanding of these dynamics changed so much once I started seeing us as swimming in the atmosphere rather than merely breathing it. Thank you for the encouragement.

Fantastic teacher, you just got many kids interested in science! I wish I took my education a lot more seriously in highschool/middle school instead of waiting until college. Keep inspiring the next generation!

Yes! The sun unevenly heats the earth for a variety of reasons. Latitude influences angle/intensity of sunlight and surface type influences how much energy is absorbed or reflected. Here is another video I made with the same illustration to explain wind. kzbin.info/www/bejne/oIm1aaqhn7SdjZo

[@markrandall2997]

I was waiting for the answer to what those pressures caused to happen in the weather hopefully you can make a video explaining that part as the video cut off because you went back to it. I'm guessing you were going to talk about rain in low pressure and dry in high pressure. But I think it'd be awesome using the tank to explain how and why that's the case. None the less this is a amazing video explaining pressure probably no definitely the best one I've seen as I was investigating it as pertaining to deer hunting. It's brought up a lot.

[@christopherdever5536]

Hey Mark! Thanks for the comment. I am working on a new and more refined video that explains the weather part. I did kind of cut off since this was part of a series of lessons I was doing for my students. You are right that high pressure tends to be drier and clear (sunny). The air in high pressure regions generally contains less moisture initially and as it falls and warms it is able to absorb a lot of water vapor without clouds forming. On the other hand the rising air in the low pressure region generally already has more moisture in it. As it reaches the higher elevations in the atmosphere and cools it begins to condense (clouds) and precipitate (rain). Some people remember this with the statement "high/happy" and "low/lousy" I'm a bow hunter myself and it seems to me that on the days where the pressure is rising rapidly I see the most whitetail deer movement. Has that been your experience? Honestly I don't know why but I love being out on those days. Good luck and thanks for the feedback.

[@Another_Aspirant03]

In colder regions high pressure created In warmer regions low pressure is created Why the blue is going towards the red and why it's going beneath the red? -Because High pressure always attracts to low pressure. Low pressure zone has a warm air and high pressure has cold air, so cold air converged beneath the warm air because warm air is not so densed compared to cold air. Low pressure rises from Equator and sinks in subtropical low because cold winds from high pressure zone, collides with warm winds from low pressure zone and it is called hardelly cell. Ps- Assume tank mouth as the bottom of troposphere.

I'm probably older than that teacher and I've gone my whole life up until now thinking that high pressure was warm air, and low pressure was cold air. I feel so stupid lmao

[@christopherdever5536]

Well you are right in a way. High pressure often leads to warmer air as the clearer skies lead to solar warming. Low pressure tends towards clouds and rain. The thing that gets a lot of people is the cause (cooler, denser air falling and creating high pressure) and the effect (clear skies and solar warming). Thanks for the comment!
