Title: Seasonal Pressure and Precipitation Patterns.
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, and how this Hadley cell shifts with the seasons. The second layer shows how the ITCZ shifts with the seasons. The third layer shows how global highs and lows grow stronger and weaker and shift position with the seasons. The fourth layer shows how global precipitation distributions change with the seasons.
Keywords: atmosphere, precipitation, trade winds, westerlies, air pressures, atmospheric pressures, high pressure, low pressure, Pacific High, Aleutian Low, Intertropical Convergence Zone, ITCZ, global distribution of precipitation
