The 'Horse latitudes' refer to specific regions on Earth characterized by high atmospheric pressure and light, often variable or calm winds. These zones are critical in understanding global atmospheric circulation patterns.
The Horse latitudes are located in the subtropical zones, approximately:
Historically, sailing ships often became becalmed in these latitudes, leading to the name. This lack of wind significantly impacted voyages, sometimes forcing sailors to jettison livestock, including horses, to conserve water and provisions.
These latitudes are associated with the descending limb of the Hadley Cell, contributing to the stable, dry conditions often found there.
