doldrums

Regions of calm, light variable winds and thunderstorms girdling the ocean near the equator and varying in extent and position according to the season. The doldrums lie between the northeasterly tradewinds of the Northern Hemisphere and the southwesterly tradewinds of the Southern Hemisphere, roughly between latitudes 10°N and 10°S. Air heated at the earth’s surface rises in the doldrums region and flows northeastward and southwest-ward at heights from 0.8 to 6 km to form anti-tradewinds. The doldrums are low-pressure calm latitudes and the horse latitudes are high-pressure calm latitudes.
