The Gulf Stream is a river in the deep sea, straits of Florida, in the Atlantic Ocean that is formed by warm currents leaving the Gulf of Mexico and squeezed between Cuba and the Florida keys. This Current builds amazing speed east of the keys about 20 miles off shore and runs North.

Although the Gulf Stream cannot be seen flowing by off North America's East Coast, in Western Europe, the current's warming effect is undeniable. This video segment adapted from NOVA uses satellite imagery to illustrate the Gulf Stream's path and animations to explain how atmospheric phenomena cause it to move.
