The regions of light and unpredictable winds at about 30 degrees North and South latitudes are called the Horse Latitudes. These areas are characterized by high-pressure systems that lead to calm winds and clear skies, often causing ships to become stranded due to lack of wind. The term originated from the historical practice of throwing horses overboard when ships became becalmed and provisions ran low.
