Does air pressure have any effect on the climate or vice-versa?

Answer 1

Good question. Although climate classifications are generally based upon temperature and precipitation, it is possible to correlate the zonal arrangement of precipitation with pressure. For example, near the equatorial low pressure the convergence of warm, moist, and unstable air makes this zone one of heavy precipitation. And in the regions of the sub-tropical high pressure zone general arid conditions persist, while in the mid-latitudes dominated by numerous cyclonic lows again reflect higher precipitation amounts. Finally, in the polar regions of the earth where temperatures are low and the air can hold only small quantities of moisture, precipitation totals decline. And so in this sense pressure does have an effect on the climate classification.

Answer 2

Temperature causes air to expand or to contract, changing its density.
Cool air descends pressing down and as it slowly comes down in a spiral it gets warmer and no clouds form. Warm air goes up, thus, lowering pressure in the surface. As humid air rises, it causes clouds.
That’s why “good” weather and high pressure are usually related.

Answer 3

Air pressure is THE driving force of weather.
