What are the main reasons for the significant monsoon climate in China?

The monsoon is a large-scale wind system with significant seasonal changes in wind direction, and is a planetary-scale circulation system like the wind belt, which is caused by the difference between ocean and land temperatures in winter and summer. The monsoon blows from the ocean to the continent in the summer and from the continent to the ocean in the winter.

The main reason is the difference in the thermal properties of the sea routes.

Causes seasonal movement of air pressure and wind bands.

This in turn forms the monsoon.

Moreover, our country has a large land area.

Therefore, there is still a difference between the monsoon climate at high latitudes and low latitudes.

d, the monsoon is a type of wind in which the prevailing wind direction changes significantly with the seasons. In the vast area of eastern China, southerly winds blowing from the Pacific and Indian Oceans prevail every summer; In winter, northerly winds blow from Siberia and Mongolia.

Because the root cause of the monsoon is the difference between land and sea heat.

Moreover, China is located between the world's largest continent, the Eurasian continent, and the world's largest ocean, the Pacific Ocean, and the difference in the thermal properties of sea and land is very obvious. So.

Because China is located between the world's largest continent, the Eurasian continent, and the world's largest ocean, the Pacific Ocean, the difference in the thermal properties of land and sea is very obvious.

dBecause the specific heat capacity of water is larger, the land heats up faster and cools down faster than the ocean.

And our country is backed by the largest plate: the Eurasian plate.

Facing the largest ocean: the Pacific Ocean.

It is a country with both land and sea, and is bordered by the Pacific Ocean to the east.

Monsoon climate. The reason for the formation is the difference in heat between land and sea and the seasonal shift in the position of the pressure belt and wind belt.

The formation of the East Asian monsoon climate is due to the difference in land and sea heat. In winter, land temperatures are lower than those of the oceans at the same latitude, with cold high pressures forming over the continents and warmer low pressures forming over the oceans. The cold and high-pressure airflow moved southward, forming and affecting East and Southeast Asia.

of the winter winds. In summer, the land temperature is higher than that of the ocean at the same latitude, and a thermal low pressure forms on the land and a warm high pressure forms over the ocean. Ocean currents affect East Asia in the form of summer monsoons.

Brings abundant precipitation.

The formation of the South and Southeast Asian summer monsoon is due to the seasonal shift in the position of the wind belt in the barometric belt.

The monsoon phenomenon is a comprehensive phenomenon under the combined influence of three factors: the thermal effect of land and sea distribution, the seasonal variation of atmospheric circulation, and the specific topography.

The main reason for the significant monsoon climate in China is the sea and land factors, China faces the world's largest ocean, the Pacific Ocean, backed by the world's largest continent, the Eurasian continent, and the thermal properties of sea and land are very different. Characteristics of the climate: Monsoon climate is significant:

Northwest winds prevail in winter, which is cold and dry; In summer, southeast and southwest winds prevail, and it is warm and rainy. The monsoon types of the three-finger shed species in China are all available, and the base area is large, and the monsoon climate in the north has obvious continental characteristics. In the same period of rain and heat, summer heat is a major advantage of China's climatic resources, which is conducive to the growth of plants, and the "land of fish and rice" benefits from the same period of rain and heat; The climate is complex and diverse: the typical monsoon climate in the east, the arid and semi-arid temperate continental climate in the northwest, and the unique alpine climate of the Qinghai-Tibet Plateau.

Coupled with the influence of complex terrain, the climate of our country is more complex and diverse. Therefore, animal and plant resources are extremely abundant, and most of the world's animals and plants have suitable growth places in China; The boundary line between the monsoon area and the non-monsoon area in China is as follows: the Daxing'an Mountains-Yinshan-Bayankala Mountain-Gangdis Mountain-one line is the boundary, the west is the non-monsoon area, and the east is the monsoon leakage area; The middle and lower reaches of the Yangtze River are the plum rainy season in mid-June, and the monthly rain belt moves northward, and there are many droughts.

The main reason for the significant monsoon climate in China is the large difference between sea and land heat.

The monsoon is a large-scale convective phenomenon caused by factors such as land and sea distribution, atmospheric circulation, and large topography, with a one-year cycle. Asia is the most famous monsoon region in the world, and its monsoon is characterized by the presence of two main monsoon circulations, namely the northeast monsoon in winter and the southwest monsoon in summer.

And their conversion has a burst mutation process, and the transition period in the middle is really short. Generally speaking, November to March of the following year is the winter monsoon period, June and September are the summer monsoon period, and April May and October are the transition period between summer and winter monsoon. However, the seasons vary from region to region, so the division of the monsoon is not exactly the same.

Characteristics of the climate:

The monsoon climate is significant: the northwest wind prevails in winter, which is cold and dry; In summer, southeast and southwest winds prevail, and it is warm and rainy. The three monsoon types in China have a large area, and the monsoon climate in the north has obvious continental characteristics.

In the same period of rain and heat, summer heat is a major advantage of China's climatic resources, which is conducive to the growth of plants, and the "land of fish and rice" benefits from the same period of rain and heat;

The climate is complex and diverse: the typical monsoon climate in the east, the arid and semi-arid temperate continental climate in the northwest, and the unique alpine climate of the Qinghai-Tibet Plateau.

Coupled with the influence of complex terrain, the climate of our country is more complex and diverse. Therefore, animal and plant resources are extremely abundant, and most of the world's animals and plants have suitable growth places in China;

The boundary line between the monsoon area and the non-monsoon area in China: the Daxing'an Mountains - Yinshan - Bayan Kala Mountain - Gangdis Mountain - the first line is the boundary, the west is the non-monsoon area, and the east is the monsoon area; The middle and lower reaches of the Yangtze River are the plum rainy season in mid-June, and the monthly rain belt moves northward, and there are many droughts.

The latitude, sea and land location, and the complex and diverse terrain of China have exacerbated the complexity of the climate.

1) Latitude location: China spans a wide range of latitudes from north to south, forming a variety of temperature zones; Due to the difference in the thermal characteristics of the continent and the ocean, a cold high pressure is formed in the interior of Asia in the severe winter, and a thermal low pressure is relatively formed on the eastern and southern oceans, and the air in the high pressure area will flow to the low pressure area, which will form a northerly and northwesterly wind in China's winter. On the contrary, in summer, the continent is hotter than the ocean, the high-temperature continent becomes a low-pressure area, and the cool ocean becomes a high-pressure area, so the southeast or southwest wind from the ocean to the continent prevails in China in summer. Because the wind from the mainland brings dry air, and the wind from the ocean brings moist air, the precipitation in China mostly occurs in the summer half of May and September when the southerly wind prevails.

It can be seen that the monsoon characteristics of China are not only reflected in the change of wind direction, but also in the change of dry and wet. The characteristics of the monsoon climate in China are: cold in winter and hot in summer, dry in winter and rainy in summer.

This kind of rain and heat in the same season is very favorable to agricultural production, winter crops have been harvested or stopped growing, generally do not need much water, summer crops grow vigorously, it 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 of the eastern United States and India in the subtropical range, but compared with North Africa at the same latitude, there is an extremely dry desert climate, with an annual rainfall of only 110 mm, while the annual rainfall in South China is more than 1500 mm, and the precipitation in the northern Sahara Desert is only 200 mm, while the annual rainfall in the Yangtze River basin in China can reach 1200 mm, and the annual rainfall in the Yellow River basin is more than 600 mm, which is more than the Mediterranean Sea at the same latitude1 3. And the rain in the Mediterranean is concentrated in autumn and winter. It can be seen from this that the prosperity and development of the eastern region of our country are not unrelated to the superiority brought to us by the monsoon.

2) Sea and land location: China is far from the ocean from east to west, forming four types of dry and wet areas; : Because the heat capacity of the land is smaller than that of the ocean, when the solar radiation weakens or disappears, the continent is more likely to cool down than the ocean, so the temperature difference between the continents is larger than that of the ocean, and this characteristic is called continentalism.

China's continental climate is manifested in the following aspects: compared with other regions at the same latitude, China is the coldest country in the world at the same latitude in winter, the average temperature in January in Northeast China is 15 20 lower than the average at the same latitude, 10 15 lower in the Huanghuai River Basin, 6 10 lower in the south of the Yangtze River, and 5 lower in the South China coast; In summer, the average country in the world at the same latitude is the hottest (except for deserts). The average temperature in July is higher than the average temperature of the same latitude in Northeast China4, higher in North China, and higher in the middle and lower reaches of the Yangtze River.

3) The terrain in China is complex and diverse, which aggravates the complexity of the climate. China has a vast territory, the longest Mohe River is located in the north of 53 °N, belongs to the cold temperate zone, the southernmost Nansha Islands is located at 3 °N, belongs to the equatorial climate, and the mountains and deep valleys, the hilly basins are numerous, the area above 4500 meters on the Qinghai-Tibet Plateau is evergreen all year round, the South China Sea Islands are summer all year round, the central part of Yunnan is like spring in all seasons, and most of the rest are distinct in four seasons.

Continental character.

The significant characteristics of China's monsoon climate are mainly manifested in the continental characteristics, and the significant characteristics of China's monsoon climate are mainly manifested in high temperature and rain in summer, and rain and heat in the same period.

Monsoon climate, which refers to the climate of the area dominated by the monsoon, is a mixture of continental climate and oceanic climate. In summer, under the influence of warm and humid air currents from the ocean, the climate is hot, humid and rainy, and the climate is oceanic.
