3.2. Explain how the variation of temperature of air in the poles and the equator controls the air pressure of those regions.

Answer:
Explanation:
Well, one must take the data I will present with a grain of salt: they come from the NCAR-NCEP reanalysis daily data (t2m, downloaded from KNMI), which uses a weather prediction model to get complete fields based on regular re-initializations with observed data from around the world. I have to wonder how much of any trends is simply a consequence of changing data or biases in model behavior…or alternatively if those factors are hiding trends rather than creating them. But anyway, I found the results a little surprising. Well, some of the results.
On average, the annual average difference in the Northern Hemisphere between the lowest ~1 degree latitude band and the highest is almost 44 degrees over the whole reanalysis period. In the Southern Hemisphere, it’s almost 73 degrees (note: this is about a degree further from the Pole, I think, since . That’s not terribly surprising, I think: high elevation of the South Pole probably makes it much colder than the North Pole-well, that’s my first guess why, anyway. I am also not terribly surprised that, over the period, there has been a reduction in the difference in both Hemispheres on an annually averaged basis:
Answer:
The temperature of the air decreases with the migration from the equator towards the poles. ... When there is an increase in the altitudes, there are fewer air molecules which result in a decrease in the atmospheric pressure.
