The Northeast Trade Winds play a fundamental role in feeding the Gulf Stream system by driving the Atlantic North Equatorial Current westward across the ocean.12

These winds maintain a steady east-to-west flow, which transports a significant volume of warm surface water into the Caribbean Sea. This water is then pushed through the Yucatán Channel into the Gulf of Mexico. The accumulation of this wind-driven water creates a higher average sea level in the Gulf of Mexico compared to the open Atlantic, establishing a hydrostatic head—a pressure gradient—that serves as a primary driving force for the Gulf Stream as it exits through the Straits of Florida.23

Additionally, this flow is reinforced by the Antilles Current, which carries water along the eastern side of the Antilles, further contributing to the formation of the Gulf Stream off the North American coast.2
