Global winds occur in belts around the globe. The Coriolis force explains why winds circulate around high and low pressure systems as opposed to blowing in the direction of the pressure gradient. The warmer air lifts over the colder air mass creating an inversion. There is Ferrels law derived from Coriolis Effect, which says that in northern hemispheres, wind deflects towards the right and in southern hemisphere wind deflects towards left.
