What are the climatic characteristics of China?

China is divided into three natural regions:

1. There are three types of climate in the eastern monsoon belt < P > tropical monsoon climate: < P > The difference of thermal properties between land and sea forms winter monsoon, and the cold air mass from Siberia high in Mongolia turns to the northeast monsoon to the right due to the geostrophic bias during its southward journey. The wind belt in the pressure zone moves seasonally to form the summer monsoon, and the southeast trade wind in the southern hemisphere moves northward across the equator, and the right is the southwest monsoon under the action of geostrophic deviator.

distributed on the east coast of the mainland between 1 and 25 north latitude.

1. The temperature is high all the year round, and the annual average temperature is above 22℃, and the most Leng Yue is generally above 16℃ for half a year in winter.

2. The annual precipitation is large, the dry and rainy seasons are obvious, and the precipitation is concentrated in summer. In summer, under the control of equatorial ocean air mass, there are many convective rains, and in addition, tropical cyclones bring a lot of precipitation, which causes more summer rains than tropical dry and wet seasons. In some windward coasts, the summer precipitation even exceeds the equatorial rainy climate zone due to the topographic effect. The annual precipitation is generally above 15 ~ 2 mm. In winter, under the control of the dry northeast monsoon, precipitation is scarce.

4. Tropical cyclones prevail. Synchronized with the "summer monsoon", tropical cyclones are prevalent from mid-May to mid-September every year.

。 5. tropical monsoon forest has Savannah landscape in the transition zone to semi-arid climate.

。 6. Rice planting, jute, rubber, tea, coffee and cocoa.

Subtropical monsoon climate:

Subtropical monsoon climate is distributed on the east coast of subtropical continent at 25 ~ 35 north latitude, which is the zone where tropical marine air mass and polar continental air mass alternately control and compete with each other. It is mainly distributed in the area south of Huaihe River in Qinling Mountains and north of tropical monsoon climate type in eastern China.

The average temperature in January is generally above ℃, and it is hot in summer, and the average temperature in July is generally around 25℃, with obvious changes in Xia Feng direction in winter. The annual precipitation is generally above 1mm, mainly concentrated in summer and less in winter. This kind of climate is most typical in southeast China. In other areas, because there is a considerable amount of precipitation in winter, there is little difference between winter and summer, so it is called subtropical monsoon humid climate.

the main features of the climate in this area are: warm in winter and hot in summer, distinct four seasons, abundant precipitation and relatively even seasonal distribution.

The seasonal distribution of precipitation is summer rain, followed by spring rain, autumn rain and winter rain, but winter rainfall can also account for more than 1% of the annual precipitation. The middle and lower reaches of the Yangtze River are the areas with high winter rain ratio and the most abundant spring rain in China.

Temperate monsoon climate:

It appears on the east coast of Eurasia at about 35 ~ 55 north latitude

In winter, it is influenced by the northerly wind from the high latitude inland, and the polar continental air mass prevails, which is cold and dry; In summer, influenced by polar ocean air mass or denatured tropical ocean air mass, east and southeast winds prevail, with warm, hot and rainy seasons. The annual precipitation is about 1 mm, and about two thirds of it is concentrated in summer (hot and rainy in summer and cold and dry in winter). There are four distinct seasons throughout the year, and the weather is changeable. With the increase of latitude, the temperature amplitude in winter and summer increases correspondingly, while the precipitation decreases gradually.

Monsoon is a kind of wind whose prevailing wind direction changes obviously with the seasons. (Supplement: the area affected by tropical monsoon climate is called monsoon area, otherwise, the area not affected by tropical monsoon climate is called non-monsoon area)

Cause:

Difference of thermal properties between land and sea

Climate characteristics:

In winter, it is influenced by northerly winds from high latitudes inland, and it is cold and dry.

In summer, it is influenced by polar ocean air mass or denatured tropical ocean air mass, and it prevails in east and southeast winds. The annual precipitation is about 1 mm, and about two thirds of it is concentrated in summer (hot and rainy in summer and cold and dry in winter).
