Lecture 11: Seasonal changes in atmospheric circulation

- We look at the effects that the seasons have on the general circulation patterns on Earth as well as the impacts on the US. Also introducing the difference between weather and climate.
This was originally part of the Blue Planet lecture series at the University of New Mexico. If you are interested in weather, this lecture is now part of my "weather short course" playlist, where there are another ~15 videos similar to this one.
Amazing visuals! Makes it so much easier to understand
"Climate is what you expect, Weather is what you get" Simply, this statement is sufficient enough to find the difference between Climate and Weather.
These videos are great! Thank you! I am student glider pilot here in Switzerland and found lectures 1-11 really useful. Motivates me to learn more :-)
Thanks and glad you could use them
Amazing lectures
Fantasic video! So easy to understand
Well 3am TH-cam thinks I need to watch this
21:58 what do you mean by "its not how it works" ? Why lows then are pushed north ?
I wonder, do those people who believe that seasons depend on distance to the sun ever notice that the days are longer and the sun is higher in summer? 😁
Great series - I'd like to chime in though to point out that the difference between aphelion and perihelion is 3.4% which means that, on the basis of the inverse square law, there is a ~7% difference in solar incident radiation between the northern and southern summers, with perihelion occurring in early January and aphelion in July. Of course, this is less of a problem for the northern hemisphere but does help to clarify why Australia for example experiences significantly hotter summers than North America - 7% is a considerable difference.
BTW: We now seem to be experiencing text book sub-tropical highs - are these the "dog days of summer"?
16:42 is it the Gulf Stream that pushes the Icelandic Low so northerly?
what happened to the context? I am confused?
15:42 what application is this please?
Cool
what software/program is at 6:05?
It is a flash program that came with a textbook. Search for "Prentice Hall Geoscience Animation Library" and you can probably find it. Most browsers don't support flash anymore, but Adobe has a standalone flash player that you can download.
@@MelStrong thanks
Hi, A little request, since you are in the field of Earth Sciences can you please suggest a Good TH-cam Channel that teaches Geo-morphology and Landscape Development just like you teach. - Thank you
That's a good question but unfortunately I don't know of anything like that. But I also haven't tried looking for anything like that either.
@@MelStrong Thank you for taking time in replying for my request.
If the seasons were caused by distance from the sun, the seasons in both hemispheres would be the same.
We can predict climate better than weather? So the butterfly effect is more impactful on a five day horizon than a fifty year horizon? Your cigarette cloud example is a closed system and assumes some or all input variables are held constant. They may change for exogenous reasons during the fifty year period and some variables might have been omitted. Why has the increase in temperature consistently been less than IPCC modeled forecast scenarios? Why is there still ice at the poles? Why did Glacier National Park remove the signs saying there would soon be no glaciers?
