The Gulf Stream is a powerful current in the Atlantic Ocean. Its movement is related to density redistribution, differences in temperature, the Earth's rotation, and wind currents. Beginning in the Gulf of Mexico, it flows along the east coast of North America and across the Atlantic to Europe. The Gulf Stream carries warm water from the tropics and warms the climate of the land near where it passes. The relatively temperate weather in Great Britain is, to a large degree, controlled by the Gulf Stream redistributing energy from equatorial solar radiation to the North Atlantic.
