Global Atmospheric Circulation The Atmosphere Is Organized Into Three Circulation Cells In Both Hemisphere They Mirror 1 (285.93 KiB) Viewed 14 times

Global Atmospheric Circulation: The atmosphere is organized into three circulation cells in both hemisphere (they mirror each other). The lecture discussed how winds move within these cells. Answer the questions regarding global atmospheric circulation patterns. Make note of high and low pressure and how they work. Also note where winds collide in the atmosphere this known as convergence. In areas where winds move away from each other, this is known as divergence. At the surface, low pressure is associated with convergence of winds and high pressure occurs with divergence on winds. 90°N Polaveasterlies 60°N C Polar Front Westerlies 30°N D Sub-tropical High Northeast trade winds 0° ITCZ Southeast track winds 30°S Sub-tropical High Westerbes 60°S Polar Front Polar easterlies 90°S Idealized global atmospheric circulation (C = surface convergence, D= surface divergence) QUESTIONS: 1. At the equator winds at the surface ---- convergence or divergence (circle one) 2. What is the name of the circulation cell between the latitudes of 0 and 30° North or South latitude? 3. In what direction does the wind between the latitudes of 0 and 30° move... east or west? (circle one) 4. In what direction does the weather between the latitudes of 30 and 60° move... east or west? (circle one) 5. What does ITCZ stand for?
