Explanation:

Winds are named by the direction from which they blow. The globe is encircled by six major wind belts, three in each hemisphere. From equator to pole, the correct sequence is doldrums, trade winds, the westerlies, and polar easterlies.

1.  Doldrums: At about the equator is Intertropical Convergence Zone or doldrums, a region of light and irregular wind broken by occasional thunderstorms and squalls.

2.  Trade Winds: South of about 30 degrees the northern or northeast trade winds blow mostly from the northeast toward the equator. These were the sailor's favorite winds, since the weather was warm, and the winds usually blew steadily in an advantageous direction.

3.  Westerlies: The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.

4.  Polar Easterlies: At about the latitude of Norway, Alaska U.S.A, and northward (60-90 degrees), the Polar easterlies blow irregularly from the east and north.
