Trade winds are a pair of semi-permanent, consistent wind patterns that characterize the tropical atmosphere. These winds are part of the larger planetary atmospheric circulation system and are generated by the differential heating of the Earth's surface, which drives global air movement. Generally blowing from the subtropical high-pressure belts toward the equatorial zone, they play a critical role in establishing prevailing weather conditions and significantly influencing the movement of surface water currents in major ocean basins. The strength and direction of these winds vary with latitude and time of year but remain a fundamental driver of regional climates in tropical regions.
