Global winds. Earthâs orbit around the sun and its rotation on a tilted axis causes some parts of Earth to receive more solar radiation than others. This uneven heating produces global circulation patterns.offsite link For example, the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere.
As the trade winds blow warm surface waters away from the west coast of continents, cold, nutrient-rich water is drawn to the surface. Â© 2011 Nature Education All rights reserved. Just as Earth's rotation creates the prevailing winds, it creates surface currents within the oceans.
