Trade winds originate in the Subtropical High-Pressure belts (Horse Latitudes). In these regions, air from the upper atmosphere sinks, creating high pressure at the surface. This air then flows toward the low pressure at the equator. Because of the Earth’s ...

This is the technical definition of trade winds. They are the surface winds of the tropical atmospheric circulation. They move from the high-pressure “Horse Latitudes” (subtropical highs) to the low-pressure “Doldrums” (equatorial lows). Because of the Coriolis effect, they blow ...
Winds that blow predominantly from a single general direction throughout the year are called “prevailing winds” (or permanent/planetary winds). These include the Trade Winds, the Westerlies and the Polar Easterlies. They are caused by the global distribution of pressure and ...
Trade winds are the most “regular and stable” winds on Earth. Unlike local breezes or seasonal monsoons, they blow with remarkable consistency in both direction and speed throughout the year. This reliability is why they were named “trade” winds—from the ...
During the summer months, the subtropical high-pressure belt shifts northward. This causes the trade winds (specifically the Northeast Trades) to blow from the high-pressure regions of the horse latitudes toward the Mediterranean basin. These winds are generally dry, contributing to ...
