The Doldrums . The Doldrums, also known as the Equatorial Convergence Zone. The axis, or a portion of the broad trade wind of the tropics. This axis is the dividing line â¦ between the southeast trades and the northeast trades, of the Southern and Northern hemispheres converging around the equator.
The doldrums is an area of calm weather. The trade winds coming from the south and the north meet near the equator. These converging trade winds produce general upward winds as they are heated, so there are no steady surface winds.he trade winds are just air movements toward the equator. They are warm, steady breezes that blow almost continuously. The Coriolis Effect makes the trade winds appear to be curving to the west, whether they are traveling to the equator from the south or north.
