वायुमंडल का सामान्य परिसंचरण और ग्रहीय पवनें

This Class 11 Geography topic explains how the atmosphere circulates globally and how planetary winds develop as a result of unequal heating, pressure belts, and Earth’s rotation. Students learn about the three-cell circulation model—Hadley, Ferrel, and Polar cells—along with the trade winds, westerlies, and polar easterlies. It also introduces the Intertropical Convergence Zone, shifting wind belts, and their role in shaping global weather and climate within Atmospheric Circulation and Weather Systems.
