Meteorology is, very simply, about the difference of temperature, pressure and moisture in our atmosphere.
The equator is warm. The poles are cold. Maritime air is moist; continental one is dry. Pressure drops with altitude and so does the temperature, up to the tropopause, the top of our troposphere, right under the stratosphere and the place where all weather happens.
Because warm air rises and cold air sinks, the equator is a zone of rising air, low pressure, cooling down of moisture, formation of clouds and precipitations. That air falls back at roughly latitude 30 N and 30 S and form two belts of high pressures where we find most of the earth’s deserts. Between that and the poles where the cold air sinks, there are two fronts where warmer air rises over colder one. Here again, rising air causes condensation and precipitations.

hmm well I’d have to say earth does whatever the hell it wants, just like it has for millions of years.
