What are the main weather system characteristics of the westerly belt in the northern hemisphere? What are the main points of the answer?

Answer only temperate maritime climate and Mediterranean climate.

The west coast of the mainland at 40 ~ 60 north latitude is affected by the westerly belt all the year round, which is mild and rainy.

The west coast of the mainland between 40 and 60 degrees north latitude is dominated by westerly winds all the year round. Affected by the warm and humid air mass in the ocean, the annual precipitation is generally between 700- 1000 mm, and it is humid all year round, with little change in annual temperature. In winter, Leng Xia is neither cold nor hot, forming a temperate maritime climate. The west coast of Europe and the Pacific coast of America belong to this climate.

The temperate maritime climate is controlled by it all year round, so the precipitation is even, while the Mediterranean summer is controlled by the subtropical high zone, so it is hot and dry.

You can analyze the characteristics and causes of temperature and precipitation.
