A region's prevailing and dominant winds are often affected by global patterns of movement in the Earth's atmosphere.[1] In general, easterly flow exists at low and high latitudes globally.

In the mid-latitudes, westerly winds are the rule and their strength is at the mercy of the polar cyclone. In areas where winds tend to be light, the sea breeze/land breeze cycle is the most important to the prevailing wind; in areas which have variable terrain, mountain and valley breezes dominate the wind pattern. Highly elevated surfaces can induce a thermal low, which then augments the environmental wind flow.
