On a large circle, show and describe where the major pressure and wind belts would be found according to the 3-cell model of Earth's general circulation.?
What will be the ideal response?
ANSWER: Answers may vary, but student drawings need to illustrate the following information. At the surface, there are two major areas of high pressure and two major areas of low pressure. Areas of high pressure exist near latitude 30 degrees and the poles; areas of low pressure exist over the equator and near 60 degree latitude in the vicinity of the polar front. Knowing the way surface winds blow around these pressure systems on the three-cell model gives us a generalized picture of how surface winds blow throughout the world. The trade winds extend from the subtropical high to the equator, the westerlies from the subtropical high to the polar front, and the polar easterlies from the poles to the polar front.??
