![]() ![]() The Coriolis effect causes some winds to travel along the edges of the high-pressure and low-pressure systems. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. This happens because Earth’s rotation generates what is known as the Coriolis effect. Generally, prevailing winds blow east-west rather than north-south. Areas where prevailing winds meet are called convergence zones. Prevailing winds are winds that blow from a single direction over a specific area of the Earth. The complex relationships between fronts cause different types of wind and weather patterns. The boundary between these two areas is called a front. Winds generally blow from high-pressure areas to low-pressure areas. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air. ![]() Warm equatorial air rises higher into the atmosphere and migrates toward the poles. At the Equator, the sun warms the water and land more than it does the rest of the globe. Differences in atmospheric pressure generate winds. Landforms, processes, and impacts of wind are called Aeolian landforms, such as sand dunes and Loess deposits, which are deposits of silt. ![]() It is the great equalizer of the atmosphere, transporting heat, moisture, pollutants, and dust great distances around the globe. It is strong enough to carry sailing ships across the ocean and rip huge trees from the ground. It can dry your clothes in summer and chill you to the bone in winter. It does not have much substance-you cannot see it or hold it-but you can feel its force. Wind is the movement of air caused by the uneven heating of the Earth by the sun. ![]()
