Title: Global Atmospheric Circulation Model.
Caption: This animation contains four layers that build sequentially upon each other. The first layer shows a Hadley cell beginning at the ITCZ low-pressure zone, with air circulating to the high-pressure areas at the Tropic of Cancer and Tropic of Capricorn. The second layer develops tropical and midlatitude components, including trade winds and the westerlies. The third level adds the polar high and the polar easterlies. The fourth level indicates typical positions of the polar and subtropical jet streams, and also depicts the antitrade winds.
