What Causes Global Convection Patterns? Atmospheric Pressure and Winds The heating of the Earth’s surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. Which factor causes global wind patterns? Large global wind systems are created by the uneven heating of the Earth’s surface. These
What Are The Three Main Global Wind Belts? “Between the poles and the equator, each hemisphere has three major surface wind belts: the polar easterlies, which extend from the poles to about 60 degrees latitude; the prevailing westerlies, which stretch from about 60 degrees to 35 degrees; and the trade winds, which pick up at
What Are The Main Wind Belts On Earth? The Earth contains five major wind zones: polar easterlies, westerlies, horse latitudes, trade winds, and the doldrums. Polar easterlies are dry, cold prevailing winds that blow from the east. They emanate from the polar highs, areas of high pressure around the North and South Poles. What is
