What is the climate zone in eastern China?

Northeast China has a temperate monsoon climate, which is influenced by southeast monsoon in summer, and the temperature is higher than that in the same latitude area. The continental characteristics of the temperate monsoon climate in northeast China are remarkable. Because the mainland is mainly sandy soil and the ocean is mainly seawater. The specific heat capacity of sandy soil is relatively small, while that of seawater is relatively large. Therefore, the mainland heats up quickly and cools down quickly; The ocean is getting warmer and colder. In summer, it is obvious that the mainland heats up quickly. However, the temperate monsoon climate in China has continental characteristics, and the temperature is obviously higher. The temperate monsoon climate higher than the same latitude has no obvious continental characteristics.

In most parts of China, the direction of Xia Feng changes obviously in winter. In winter, the air flow mainly comes from the high-latitude continent, prevailing northerly winds, and in summer, the air flow comes from the low-latitude ocean, with more southerly winds. Winter is controlled by winter wind, with dry and cold climate and strong wind. In summer, the vast areas in the east are mainly affected by the summer monsoon, and the climate is humid and rainy. Spring and autumn are controlled by winter and summer monsoon, and the weather is warm and cold, sunny and rainy. There are obvious dry and wet seasons and four distinct seasons in the vast areas of southeast China.

Southeast China is affected by monsoon, and the rainy season has obvious regularity. The rainy season is early in the south and late in the north, early in the east and late in the west; The rainy season ends early in the north, late in the south, early in the west and late in the east. Affected by monsoon, the precipitation in southeast China is mainly monsoon rainfall, and the regional distribution of precipitation is uneven. It is rainy in the east and dry in the west. There is more rain in the south than in the north.

Affected by the monsoon climate, the southeast of China is dry and cold in winter, hot and humid in summer, and the annual and daily changes of temperature are greater than those in the south, which shows that there is a big difference between north and south in temperature and humidity, and the difference between winter and summer is greater.

Due to the influence of monsoon, the annual average temperature in eastern China is on the high side. Compared with other parts of the world at the same latitude, the temperature is low in winter and high in summer (not as high as in winter).

The climate in China has three characteristics: obvious monsoon characteristics, obvious continental climate and diverse climate types.

Monsoon has obvious characteristics: the wind direction changes in most parts of China within one year, which is determined by China's geographical location, mainly the allocation of land and sea. Due to the difference of thermal characteristics between the mainland and the ocean, a cold high pressure is formed in the inland of Asia, and a hot low pressure is formed in the eastern and southern oceans. If the air in the high-pressure area flows to the low-pressure area, it will form the northerly and northwest winds in winter in China. On the contrary, in summer, the continent is hot in the ocean, the high-temperature continent becomes a low-pressure area, and the cool ocean becomes a high-pressure area. Therefore, the southeast wind or southwest wind from the ocean to the mainland prevails in summer in our country. Because the wind from the mainland brings dry airflow and the wind from the ocean brings humid air, the precipitation in China mostly occurs from May to September in the summer when the south wind prevails. It can be seen that the characteristics of China monsoon are not only reflected in the change of wind direction, but also in the change of dryness and wetness. The monsoon climate in China is characterized by hot Leng Xia in winter, dry winter and rainy summer. This climatic feature of the same season of rain and heat is very beneficial to agricultural production. Winter crops have been harvested or stopped growing, and generally do not need much water. Summer crops grow vigorously, which is the season that needs a lot of water. Compared with the same latitude zone, the seasonal distribution of precipitation in China is similar to that in the subtropical eastern United States and India, but compared with that in North Africa at the same latitude, it belongs to an extremely dry desert climate, with an annual rainfall of only 1 10 mm, while that in South China exceeds 1500 mm, and that in the northern Sahara desert is only 200 mm, while that in the Yangtze River basin in China can be seen.

Obvious continental climate: Because the heat capacity of the land is smaller than that of the ocean, when the solar radiation weakens or disappears, the land is easier to cool down than the ocean. So the temperature difference between the mainland and the ocean is greater than that of the ocean, which is called continental.

Chinese mainland's climate is as follows: compared with other regions in the same latitude, China is the coldest country in the same latitude in winter in the world, and the average temperature 1 month is lower than that in the northeast 15 ~ 20℃, that in Huanghuai basin10 ~/5℃, and that in the south of the Yangtze River is 6 ~/kloc-0 ~ 0℃. Summer is the warmest country in the same latitude in the world (except desert). The average temperature in July is 4℃ higher in the northeast than in the same latitude, 2.5℃ higher in North China and 1.5 ~ 2℃ higher in the middle and lower reaches of the Yangtze River.

Various climate types: China has a vast territory. The longest Mohe River is located in the north of 53° N, which belongs to the cold temperate zone, and the southernmost part of Nansha Islands is located at 3 N, which belongs to the equatorial climate. In addition, there are many mountains, deep valleys and hilly basins. The Qinghai-Tibet Plateau above 4,500 meters is always in winter, the islands in the South China Sea are always in summer, and the central Yunnan is like spring. Most other areas have distinct seasons.
