(Nautical Terms) nautical the latitudes near 30°N or 30°S at sea, characterized by baffling winds, calms, and high barometric pressure
[C18: referring either to the high mortality of horses on board ship in these latitudes or to dead horse (nautical slang: advance pay), which sailors expected to work off by this stage of a voyage]
the latitudes, approximately 30° N and S, forming the edges of the trade-wind belt, characterized by high atmospheric pressure with calms and light variable winds.
[1765–75; probably as translation of Sp golfo de las yeguas literally, mares' sea]
Either of two regions of the globe found over the oceans about 30 degrees north and south of the equator. Because winds are generally light and unsteady in the horse latitudes, sailing ships were often caught in them for days without enough wind to move.
Subtropical belts of atmospheric high pressure; calm regions in both hemispheres between the westerlies and the trade winds.
