Detailed data of maritime climate on the west coast of Chinese mainland.

The maritime climate on the west coast of the mainland is also called temperate maritime climate.

The maritime climate on the west coast of the mainland is mild and humid all year round. Its characteristics are very obvious: there is no severe cold in winter, no heat in summer, and the precipitation is relatively uniform all year round, distributed on the west coast of the mainland between 40 degrees and 60 degrees north latitude.

This climate is affected by prevailing westerly winds all year round, and the west coast is often affected by warm current, which increases the temperature and humidity. The west wind blows from the warm ocean surface, and there is a lot of precipitation. Temperate frontal cyclones often strike in winter, so although it rains all year round, the rainfall in autumn and winter is usually slightly higher than that in spring and summer. The rain is mostly light rain and showers, and there are almost no thunderstorms. Cyclones frequently transit, with an annual rainfall of 500-700mm, exceeding 2500mm in areas with favorable terrain (such as northwest North America).

The average temperature in Leng Yue is above 0℃, and the warmest month is below 22℃. Annual range is much smaller than inland and east coast areas of the same latitude. It belongs to the northwest of Europe, the Pacific coast of Canada, southern Chile, southeastern Australia, New Zealand and other small areas. It is found in all continents except Asia, Africa and Antarctica, with Western Europe and the British Isles as the most typical ones.

Chinese name: Chinese mainland west coast maritime climate mbth: West coast maritime climate, also known as temperate maritime climate features: warm and humid throughout the year, with even precipitation distribution. Continent: Europe, North America, Oceania and South America. Subject: geographical origin, characteristics, distribution and influence. Agriculture, life and reasons The main reason for this climate is that 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. 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 and expand the influence of the Atlantic Ocean, making the maritime climate on the west coast of Europe particularly typical. Features 1, warm in winter and cool in summer, with small annual temperature difference. The closer 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 hottest month temperature affected by the west wind 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. It rains all year round, and it rains more 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 diurnal changes of temperature are very small, and even the diurnal changes 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 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. 5. In stormy tropical seas, such as the southwest of the North Pacific and the South China Sea of China, typhoons have a strong generation and influence. Tropical storm (including typhoon) is a very important meteorological disaster. 6. cloudy weather and 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. Located on the west coast of the mainland at 40-60 degrees north and south latitude, it is distributed on all continents except Asia and Antarctica, with Western Europe and the British Isles (European continent) as the most typical ones. The maritime climate on the west coast of the mainland is often only distributed in narrow strips or islands. The maritime climate on the west coast of the mainland is the most typical in western Europe, with the largest distribution area. It is also distributed in the corresponding latitude zone on the west coast of the American continent, Tasmania and New Zealand in Oceania. It belongs to northwest Europe, the Pacific coast of Canada, southern Chile and a small part of southeast Australia. Western Europe is located at about 30-40 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 maritime climate affecting the west coast of the mainland, with high latitude, rainy and light and heat conditions, is generally not suitable for the development of planting (except for the Paris Basin, where the heat conditions are good and there are planting distribution). Generally, animal husbandry (such as northern Scotland) and flower planting (such as Holland) are the main agricultural types with less heat requirements. The climate of agriculture is not conducive to the growth of food crops and oil crops, but it is conducive to the growth of juicy pastures. At the end of 19, it was found that in Europe, the protein content of long-grain wheat produced by marine climate was low, only 4-8% at most. Protein content of wheat increased by 9 ~ 12% as it reached the European part of Russia. In dry and hot areas, the protein content of wheat increased to 65438 08%, even more than 20%. Scientists in the former Soviet Union proved that the stronger the continental climate in a region, the higher the protein content of wheat. In the cool and humid climate, the starch content of wheat increased, while the protein content decreased. People have to rely on meat to supplement protein's deficiency, but it also brings the disadvantage of too much fat. It can be seen that the maritime climate is not very beneficial to agriculture. The mild, cloudy and humid maritime climate gives people a comfortable feeling; In fact, living in a maritime climate is mild, but gloomy and rainy weather is not conducive to people's spiritual and emotional development.
