The complete diagram summarizing atmospheric circulation. Note that rising warm, moist air results in a low pressure zone and descending cold, dry air results in a high pressure zone. These zones of high and low pressure along with the Coriolis force create the major wind belts. Note: The Hadley cell extends from the equator to about 30 degrees N and S latitude, the Ferrel cell extends from about 30 to 60 degrees N and S latitude and the Polar cell extends from 60 degrees latitude to the poles (90 degrees N and S latitude).
