Гольфстрим
The climate of Western Europe is milder in comparison to other areas of the same latitude around the globe due to the influence of the Gulf Stream. Mediterranean waters are not as deep as the large oceans, allowing it to become a heat storage tempering winters along its coastlines, but because the Atlantic Ocean is largely influenced by the gulf stream, this effect is reduced when compared to that of the Atlantic waters. The Gulf Stream is nicknamed "Europe's central heating", because it makes Europe's climate warmer and wetter than it would otherwise be.
