Grvity And Atmospheric Currents:

The rotation of the Earth exerts a tangential attraction into the atmosphere producing an east to west current which carry clouds along to produce weather.

 HOW GRAVITY DRIVES WEATHER CURRENTS. 

The east to west atmospheric currents that carry  clouds along and determining weather are mainly powered by the earths rotation. As the Earth rotates from west to east, wind blows from east to west carrying with it clouds, which determine the prevailing weather of an area in relation to the prevailing season.

Gravity is relative and proportional to the motion and velocity of a body in motion;(General Theory Of Gravitational Dynamics And Life; "to be published"), and for this reason the rotation of the earth imparts a tangential attraction in the atmosphere causing an east to west wind currents which carry the clouds along with them in the opposite direction (see diagram above).  

This effect is mainly observed along the equator, however, different gravitational interactions at different points of the earth's globe can produce different patterns of  wind currents especially in the upper and lower hemispheres.

If the earth's rotation ground to a halt, most of its  weather activities will cease forthwith. Therefore, a planets weather is for the most part is driven by its ration.
