What are the characteristics of temperate maritime climate?

1, warm in winter and cool in summer, with small annual temperature difference.

The closer the maritime climate zone is to the ocean, the stronger the maritime climate. Especially in winter, because there is a warm current along the coast, the west wind blows from the warm current sea surface, and the airflow is warm and humid, so the temperature in winter is much warmer than that in the continental center and the eastern coast of the mainland at the same latitude. The lowest monthly average temperature is above 0℃. In summer, the water temperature of the warm current is still lower than that of the mainland, and the sea is much cooler than the land. The average temperature of the hottest month affected by the westerlies here is below 22℃. Because it is warm in winter and cool in summer here, the annual temperature difference is much smaller than that in other areas of the same latitude.

2, the rainy season all year round, more rain in winter.

There is abundant cyclone rainfall in this area, especially in winter, with more rainy days, but the precipitation intensity is not great. Winter precipitation accounts for a slightly larger proportion of the whole year, and there is no dry season throughout the year. In this paper, the characteristics of temperate maritime climate are summarized in one sentence: there is no cold in winter and no heat in summer.

3. The annual and daily changes of temperature are very small.

Even on the surface of the ocean, no diurnal variation can be observed. The annual extreme value is generally 1 month later than that of Chinese mainland, such as February in Leng Yue and August in the warmest month. At high latitudes, Leng Yue may be in March and the hottest month may be in September. Autumn is warmer than spring.

4. The seasonal distribution of precipitation is relatively uniform.

There are many days of precipitation, but the intensity is small. There are many clouds and high humidity.

There are many storms in the tropical ocean.

For example, the southwest part of the North Pacific Ocean and the South China Sea of China are areas where typhoons are generated and have a strong influence. Tropical storm (including typhoon) is a very important meteorological disaster.

6, cloudy weather, high humidity

Most of the mainland areas near the ocean have maritime climate characteristics, and the coastal areas of western Europe are typical maritime climate areas on the mainland.

Extended data:

The main reason for this climate is that this area is located on the west coast of the mid-latitude (40 ~ 60) mainland, and it is westerly all 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. After landing, it will be lifted by the terrain, so that a large amount of precipitation can be realized.

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.

2. Oceania: Hobart (Australia), Wellington (New Zealand) and Auckland (New Zealand)

3. North America: Vancouver (Canada), Seattle (USA) and Juno (USA).

4. South America: puerto montt (Chile), punta arenas (Chile) and ushuaia (Argentina)
