There are a very interesting set of “movies” of various earth processes here:
You can watch a set of data, like precipitation, wander up and down the globe over a set of years. It is interesting to look at net radiation, surface temperature, water vapor, precipitation, etc. “They all go together when they go!” comes to mind. The major ‘takeaway’ for me is pretty simple.
There’s a band of “more” at the equator and a whole lot “less” at the poles. The band of “more” wanders up and down with the earth changing tilt. You can SEE the heat flux being pick up and dumped, via water flows, and without a whole lot of latitudinal transport of the energy involved.
Yes, there is some lack of alighment, but not much. So, for example, sea surface temperatures don’t move as much as some other things. No real surprise, it has a lot more mass. By the time you have clouds, they are more diffuse and wander a bit more (or have less pronounced gradations). But the pattern of the seasonal wander still shows up.
It doesn’t take long to look at the movies ( a minute? or so each). They can be opened in separate windows if you wish and could be run ‘side by side’ if desired.
We’ll start with ‘net flux’ or ‘net radiation’:
And the result in sea surface temperature:
Leading to Water Vapor:
Which rises to altitude as clouds (releasing energy in condensation at altitude):
Then falling back to Earth as precipitation.
So we can see the whole process, from radiation in, to temperatures, to heat out, to precipitation. It happens in bands, with all of them moving seasonally; with the max moving with the sun near the equator.
Not a whole lot of room for CO2 to do a darned thing. Anyplace that did warm by a degree or two, would just rapidly have a lot of water transport and dump the heat. We’ve got a dramatic “existence proof” here, IMHO, as we can watch places go from nearly no ‘flux’ to very high flux each and every yearly cycle and see just what happens. What happens is it gets cloudy and rains.
One other implication of this is that any generalized cooling off of the sun will result in lower precipitation globally. There may well be some locations that get more due to given ocean currents, such as the Gulf Stream, and lag time between things like warming near Florida and arrival at England… Or places that get excess rains as a ‘loopy jet stream’ dumps more wet air on their heads; but generally, I would expect more droughts on a global scale.
So enjoy the movies and contemplate just what they mean.
