The North Atlantic Drift is a warm ocean current that originates from the Gulf Stream. It flows across the North Atlantic Ocean, bringing mild temperatures to the western coasts of Europe, particularly affecting countries like Ireland and Norway. This current plays a crucial role in moderating the climate of these regions, making them warmer than other areas at similar latitudes. As part of the larger Atlantic Meridional Overturning Circulation, the North Atlantic Drift helps distribute heat across the ocean. Its influence extends to weather patterns, contributing to the relatively mild winters experienced in parts of Western Europe. The current is vital for marine ecosystems and supports various fish species.
