North Atlantic Drift, warm ocean current in the northern part of the Atlantic Ocean. It is a continuation of the Gulf Stream, the merging point being at lat. 40°N and long. 60°W. Off the British Isles it splits into two branches, one going south (the Canary Current) and the other going north along the coast of W and N Europe, where it exerts considerable influence upon the climate as far as northwestern Europe.
