(1) Europe is surrounded by the sea on three sides, which looks like a "big peninsula" protruding westward from the Eurasian continent;

(2) The continental contour is broken, the coastline is long and tortuous, and most areas are not far from the sea;

(3) Most of them are located between 40 and 60 north latitude, and the warm and humid westerly winds from the Atlantic Ocean prevail all the year round;

(4) There is a warm North Atlantic current along the coast, which makes the northwest coast significantly warm;

(5) The mountains are mostly east-west, and the plains are widely connected, which is beneficial to warm and humid air in the Atlantic Ocean.

(6) The population density is high, the proportion of urban population is large, and the waste heat emission is high;

The above factors have played an important role in the formation of a remarkable temperate maritime climate in Europe.
