The climate on the west coast of the United States
Cause of formation: It is controlled alternately by westerly belt, subtropical high belt and trade wind belt. In winter, the westerly wind zone moves south to this climate zone, and the westerly wind brings humid airflow from the ocean. In addition, frontal cyclones are frequent, so the climate is mild and rainy. In summer, the subtropical high or trade winds move northward in this climatic zone, and the airflow sinks mainly. Coupled with the coastal cold current, it is not easy to form precipitation, so the climate is dry and hot.

Classification of Mediterranean climate:
1, cool in summer, subtropical and dry in summer: In the Mediterranean climate zone near the ocean, due to the cold current along the coast and the influence of land and sea winds, it is cool in summer, with less sunshine and foggy, and the hottest month is below 22℃. Summer is hot and dry, and winter is mild and rainy.
2. Warm summer and subtropical dry summer climate: In the Mediterranean climate zone, which is a little far from the ocean, the temperature is very high in summer under the control of subtropical high, and the hottest month is above 22℃. There is more sunshine, and the annual change range is larger than that of summer cool type.
