Question

give reason why the ports of North Western Europe remain open even during the winter

Answer 1

this occurs due to the effect of the warm North Atlantic Drift, which is a continuation of the Gulf Stream. At the Cape Hatteras, Gulf Stream is deflected eastwards under the influence of rotation of the Earth and the westerlies, which flows as the North Atlantic Drift. Because The Gulf Stream causes rain and keeps the harbors clean from being frozen due to long winters.
