What Is Shown on a Prevailing Wind Patterns Map?


Quick Answer

A map of the earth's prevailing winds system will likely show the arrangement, location, direction and wind speed of the various dominant wind patterns blowing across the earth's surface. Such a map might identify easterly or trade winds, located near the equator; westerly winds or westerlies, located between 35 and 65 degrees latitude; and the polar easterlies, located near the North and South Poles.

Prevailing winds blow mostly from one direction and are influenced by the earth's meteorological and atmospheric conditions, as well as its movement and position. In general, a prevailing winds map includes arrows signifying the cardinal direction of various wind patterns as they move across the earth's surface. More detailed maps - especially those used by professional meteorologists - typically include more precise data on wind direction, speed and arrangement in reference to other wind systems.

Prevailing winds are a significant force in climatology, often determining the climate for a particular region. They are particularly useful for predicting fair or inclement weather but also for predicting the landfall of a hurricane or cyclone. Meteorologists use tools called wind roses to determine the wind speed and direction of a prevailing wind at a specific location on the earth's surface.
