Atmospheric Circulation and Weather Systems

NCERT Fundamentals of Physical Geography, Class 11, Chapter 10 explains how uneven heating sets the atmosphere in motion. Warm air rises at the equator and sinks in the subtropics, forming Hadley, Ferrel, and polar cells that shape trade winds, westerlies, and polar easterlies. The chapter links pressure belts, jet streams, and shifting wind zones to monsoons, cyclones, and daily weather. Diagrams of circulation cells help readers connect global wind patterns with the rain and storms experienced in India.
