What are the climatic characteristics of temperate maritime climate?

The temperate maritime climate is distributed on the west coast of the mainland at 40-60 degrees north and south latitude, and it is distributed on all continents except Asia, Africa and Antarctica, with Western Europe and the British Isles as the most typical ones. Temperate maritime climate is often only distributed in narrow strips or islands. The temperate maritime climate is the most typical in western Europe, with the largest distribution area, and also distributed in the west coast of the American continent, Tasmania in Oceania and the corresponding latitudes in New Zealand. It belongs to a small part of northwest Europe, Pacific coast of Canada, southern Chile, South Africa and southeastern Australia. Western Europe is located at about 30-40 degrees north latitude, which is influenced by the west wind and the water vapor from the Atlantic Ocean. The topography of North America is higher in the west, lower in the middle and slightly higher in the east. The water vapor blown from the Pacific Ocean is blocked by the Rocky Mountains, which can only affect the coastal marginal areas, and the Alaska Warm Current passes by. Therefore, the scope of northern Europe is large, and the scope of North America is small. The climate is located on the west coast of the mainland, 40 ~ 60 north latitude. Being in the westerlies all the year round, it is deeply influenced by the ocean air mass, and there is a warm current passing along the coast. There is no cold in winter and no heat in summer. The average temperature in Leng Yue is above 0℃, the hottest month is below 22℃, and the annual and daily temperature difference is small. There is precipitation all year round, especially in autumn and winter. The annual precipitation is above 1000mm, and the windward slope in mountainous areas can reach above 2000 ~ 3000 mm. This kind of climate is the most typical in western Europe, with the largest distribution area, and it is also distributed in the corresponding latitude of America, the west coast of Africa, Tasmania and New Zealand in Oceania. This climate type is influenced by the west wind all the year round, and the ocean air mass prevails. Its main characteristics are mild and humid, and the temperature difference is small. The highest and lowest monthly average temperatures are in August and February respectively, and the monthly average temperatures are not lower than 0℃ and not higher than 22℃. The precipitation is 500 ~ 700 mm, and the local windward slope can reach 2500 mm. Due to cyclone rainfall, the precipitation intensity is very small, there are many rainy days and insufficient illumination. Not suitable for the growth of food crops. Natural vegetation is dominated by broad-leaved deciduous forests and mixed forests. Compared with continental climate, the main characteristics of temperate maritime climate are that not only the annual and daily variations of temperature are small, but also the extreme temperature appears later than that of continental climate zone; The seasonal distribution of precipitation is relatively uniform, with more precipitation days and less intensity; There are many clouds and high humidity. Judging from the annual temperature change, spring is colder than autumn, and temperate maritime climate is an obvious sign of maritime climate. The warmest month appears in August and even lasts until September; Leng Yue is the most in February, and the high latitudes are postponed to March. People usually regard the coastal areas of northwest Europe as a typical maritime climate on the mainland. The climate in the vicinity of the ocean. For example, the prevailing wind on an island or continent comes from the climate of parts of the ocean. The climate formed by the action of huge water bodies in the ocean. Including the ocean surface or island and the climate of the offshore part of the mainland where the main airflow comes from the ocean. Compared with continental climate, the main feature of maritime climate is that not only the annual and daily variation of temperature is small, but also the extreme temperature appears later than that in continental climate area. The seasonal distribution of precipitation is relatively uniform, with more precipitation days and less intensity; There are many clouds and high humidity. Judging from the annual temperature change, spring is colder than autumn, which is an obvious sign of maritime climate. The warmest month appears in August and even lasts until September (such as San Francisco); Leng Yue is the most in February, and the high latitudes are postponed to March. People usually regard the coastal areas of northwest Europe as a typical maritime climate on the mainland. Marine climate is the most basic climate type on the earth. The general feature is that it is less influenced by the mainland and more influenced by the ocean. Under the condition of maritime climate, the annual and daily variations of temperature are relatively mild, and the daily variation of annual variation is smaller than that of continental climate. The temperature in spring is lower than in autumn. The annual maximum and minimum temperatures appear later than continental climate; The hottest month is in August and the hottest month in Leng Yue is in February. The climate formed by the action of huge water bodies in the ocean. Including the ocean surface or island and the climate of the offshore part of the mainland where the main airflow comes from the ocean. The maritime climate has the following characteristics: ① The annual and diurnal variations of temperature are very small, and even the diurnal variations are not observed on the ocean surface. 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 warmest month may be in September (such as San Francisco). Autumn is warmer than spring. (2) The seasonal distribution of precipitation is relatively uniform, with more precipitation days but less intensity. There are many clouds and high humidity. (3) There are many tropical ocean storms, such as the southwest of the North Pacific and the South China Sea of China, where typhoons have a strong influence. Tropical storm (including typhoon) is a very important meteorological disaster. ④ Cloudy weather with 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.
