The answer to the question is Continental deflection. The Gulf Stream Current is deflected by North America, causing the current to change direction. This concept is referred as the Continental deflection. It occurs when a continent deflects the movement of a current (water or air). Continental deflection can either be: Defelction by rotation and continental position --->North Atlantic as an example Deflection of equatorial currents by South America
The Gulf Stream begins upstream of Cape Hatteras, where the Florida Current ceases to follow the continental shelf. The position of the Stream as it leaves the coast changes throughout the year. In the fall, it shifts north, while in the winter and early spring it shifts south (Auer 1987; Kelly and Gille 1990; Frankignoul et al. 2001).
