Atmospheric Circulation Cells Diagram - Hadley, Ferrel, and Polar Cells Explained #74950 (License: Personal Use)

This black-and-white schematic depicts Earth’s three primary atmospheric circulation cells-Hadley (0°-30°), Ferrel (30°-60°), and Polar (60°-90°)-with labeled latitudes, pressure belts (e.g., ITCZ, subtropical highs), and prevailing wind directions. Arrows indicate airflow: rising at the equator and poles, sinking at 30° and 60°, and surface winds including trade winds, westerlies, and polar easterlies. The diagram also marks key features like anticyclones and cyclones in mid-latitudes.

Used in meteorology, climatology, and earth science education to explain global wind patterns, weather systems, and climate zones; ideal for textbook figures, lecture slides, or科普 articles targeting students and educators seeking foundational atmospheric dynamics knowledge.
