The idealized global pattern of surface wind from the Equator to the Pole is known as the atmospheric circulation. It is a result of the Earth`s rotation and the temperature differences between the Equator and the Poles.

Option 1: Doldrum - Westerlies - Trade Wind - Easterlies

Doldrums are regions of calm winds near the Equator, so this option is incorrect. The correct sequence should start with the Doldrums.

Option 2: Easterlies - Westerlies - Trade Wind - Doldrum

Similarly, Easterlies are winds blowing from the Polar Regions towards lower latitudes. So, this option is also incorrect.

Option 3: Doldrum - Trade Wind - Westerlies - Easterlies (Correct Answer)

The Doldrums are the equatorial region of calm winds, followed by the Trade Winds. Trade Winds blow towards the equator from the subtropical regions in both hemispheres. Then comes the Westerlies, which blow from the west in the mid-latitudes. Finally, Easterlies blow from the Polar Regions towards lower latitudes.

Option 4: Westerlies - Trade Wind - Doldrum - Easterlies

This option is also incorrect as it does not
