Which one among the following is the idealized global pattern of surface wind from the Equator to Pole ? ,
Explanation
The idealized global pattern of surface winds from the Equator to the Pole follows a sequence determined by atmospheric circulation cells. At the Equator (0°), the Intertropical Convergence Zone (ITCZ) creates a belt of calm, rising air known as the Doldrums [3]. Moving poleward, the surface component of the Hadley Cell produces the Trade Winds (tropical easterlies), which blow from the subtropical high-pressure belts toward the Equator [1]. Between 30° and 60° latitude, the Ferrel Cell generates the Westerlies, which blow from the west toward the poles [2]. Finally, in the polar regions (60° to 90°), the Polar Cell results in the Polar Easterlies, where cold air subsides and blows toward the mid-latitudes [4]. Thus, the correct sequence from Equator to Pole is Doldrum, Trade Wind, Westerlies, and Easterlies [t4][t5].
