The heat and solar energy from the Sun keep evaporating water from oceans and lakes and the air in the atmosphere moving (primarily due to convection), which creates changes in weather. The "Coriolis" effect causes large weather systems to rotate.
The turbulence creates different pressure zones and fronts.
