For example, the wind that occurs in the North and South Poles is different to the wind that Air movements (winds) blowing towards the equator, channeled west by the Coriolis effect. These major regions of surface circulation and their associated pressure fields are related to mean meridional (north-south) circulation patterns as well (see the diagram). The direction of wind is also affected by coriolis affect. Stormcenter - School / Business Application. Between these low- and high-pressure regions is the region of the tropical winds.
