Named from their ability to quickly propel trading ships across the ocean, the trade winds between about 30 latitude and the equator are steady and blow about 11 to 13 miles per hour. When this occurs, a narrow ridge of high pressure forms between the two convergence zones. 3. The northeast and southeast trade winds meet there; this meeting causes air uplift and often produces clusters of convective thunderstorms. "Trade Winds, Horse Latitudes, and the Doldrums."

The Doldrums are generally located between 5 degrees latitude north and south, but they can extend as far as 18, depending on the season. UTC). It's a place for trade winds to meet other trade winds. [16] A southward shift of the ITCZ commencing after the 1950s and continuing into the 1980s may have been associated with cooling induced by aerosols in the Northern Hemisphere based on results from climate models; a northward rebound began subsequently following forced changes in the gradient in temperature between the Northern and Southern hemispheres. The ITCZ moves north and south of the equator depending on the season and solar energy received.

Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. The trade winds converge in the region of the ITCZ, producing convectional storms that produce some of the world's heaviest precipitation regions. The crews of sailing ships dreaded the doldrums because their ships were often becalmed there; the designation for the resultant state of depression was apparently thus extended to these geographic regions themselves. polar esterlies. Then there are the prevailing westerlies in the higher latitudes and the polar easterlies near both poles.
