What are the manifestations and reasons why the climate in western Europe is deeply influenced by the ocean?

Performance: The climate in Western Europe is deeply influenced by the Atlantic Ocean. The climate is mild and humid, with obvious maritime characteristics (mild winter, cool summer, daily temperature difference less than annual temperature difference, and even distribution of precipitation season throughout the year), and it gradually transits from maritime climate to continental climate from west to east.

Reason: This area is located on the west coast of the mid-latitude (40 ~ 60) mainland, and the west wind blows all the year round. The wind blows from the West Sea, and there is a warm current along the coast, which makes the west wind warmer and wetter. Terrain uplift after landing can cause a lot of precipitation. As far as Western Europe is concerned, the coastal North Atlantic warm current is very strong, with high temperature and humidity, and the coast is particularly tortuous. The Mediterranean Sea and the Baltic Sea extend inland. In addition, western Europe is low-lying, with plains and mountains running east-west. Therefore, westerly winds and cyclones can go deep inland, expanding the scope of the Atlantic Ocean, making the temperate maritime climate in Western Europe particularly typical.
