Sub-tropical high pressure belts are also referred as:

Key Points

• Sub-tropical high-pressure belts are located between 30° and 35° north and south latitudes.
• These belts are characterized by calm winds, known for their lack of strong horizontal air movement.
• The term "Horse Latitudes" originated from the historic practice of sailors throwing horses overboard to lighten the ship during calm periods.
• These regions are associated with descending air, leading to clear skies and dry weather conditions.

Additional Information

• Doldrums: The doldrums refer to the equatorial regions between 5° north and south latitude, characterized by low pressure and weak winds. These areas are known for their unpredictable weather patterns, including thunderstorms and calm periods.
• Wind Convergence: Wind convergence occurs when winds from different directions meet and rise, leading to cloud formation and precipitation. This phenomenon is common in the Intertropical Convergence Zone (ITCZ).
• Frontal Rains: Frontal rains are associated with the meeting of two air masses of different temperatures, leading to the formation of a front. The warm air rises over the cold air, causing precipitation. This type of rain is common in temperate regions.
