Gulf Stream. The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.
The Gulf Stream, also known as the North Atlantic Drift, is a warm current which flows across the Atlantic Ocean from the warmer seas of the Caribbean and makes West-European countries considerably warmer than they would be otherwise. The Gulf Stream is the main ocean current that affects Britain and warms it by 5-8C. The Gulf of Mexico has higher air temperatures than Britain, as it's closer to the equator. This means that the air coming from the Gulf of Mexico to Britain is also warm. However, the air is also quite moist as it travels over the Atlantic Ocean.
