horse latitudes  (hôrs)

Either of two regions of the globe, found over the oceans about 30 degrees north and south of the equator, where winds are light and the weather is hot and dry. They are associated with high atmospheric pressure and with the large-scale descent of cool dry air that spreads either toward the equator, as the trade winds, or toward the poles, as the westerlies.
