it's energized with latent heat. Then, subject to atmospheric circulation, the water vapor moves at the whim of systems of low and high pressure. These systems and the winds they produce result from how the earth rotates on its axis *like a ballerina*, as well as differences in heating and cooling of the earth's surface during different seasons and latitudes. More on this later..
