How are local winds and global winds differ? local winds-are winds that blow over short distances caused by unequal heating of the earths surface in a small area. global winds-are winds that blow around the earth from â¦ the north pole to the south pole.
The dominant winds are the trends in direction of wind with the highest speed over a particular point on the Earth's surface.A region's prevailing and dominant winds are often affected by global patterns of movement in the Earth's atmosphere. In general, easterly flow occurs at low and medium latitudes globally.In the mid-latitudes, westerly winds are the rule and their strength is largely determined by the polar cyclone.n 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.
