What are the climatic characteristics of Chengdu?

Chengdu climate: subtropical monsoon humid climate.

It is characterized by early spring, hot summer, cool autumn and warm winter. The annual average temperature is 16℃, and the annual rainfall is about 1000 mm. A remarkable feature of Chengdu's climate is cloudy and short sunshine time. The folk proverb "Shu dog barks at the sun" is an image description of this climate feature.

Another notable feature of Chengdu's climate is humid air. Therefore, although the temperature is not high in summer (the highest temperature generally does not exceed 35℃), it looks sultry. In winter, the average temperature is above 5℃, but it is very cold because of cloudy days and humid air. The rain in Chengdu is concentrated in July and August, and there is less rain and less ice and snow in winter and spring.

Extended data:

The extreme minimum temperature in Chengdu is -5.9℃, with most districts and counties appearing in 65438+February and a few in 65438+ 10. Chengdu belongs to the subtropical humid monsoon climate zone, and the most frequent wind direction in Chengdu all year round is static wind; The second wind direction: north wind in June, July and August, and north-northeast wind in other months.

Chengdu is located in the western edge of Sichuan Basin, and its terrain inclines from northwest to southeast. The western part belongs to the marginal area of Sichuan basin, mainly composed of deep mountains and hills, with an altitude of1000 ~ 3000m. The highest point is located in the University Hall (Miaojiling) of Xiling Town, Dayi County, with an altitude of 5364 meters.

The eastern part belongs to the basin-bottom plain of Sichuan Basin, which is formed by alluvial rivers such as Minjiang River and Yujiang River. It is the center of Chengdu Plain, mainly composed of plains, terraces and some low hills. The altitude is generally about 750 meters, and the lowest is on the bank of Tuojiang River in jianyang city, with an altitude of 359 meters.

Due to the huge vertical height difference, Chengdu has formed a unique landform type of one-third plain, one-third hill and one-third mountain. Due to the obvious climate differentiation, a vertical climate zone with obvious heat difference has been formed, so there are many kinds, complete categories and relatively concentrated distribution of biological resources in this area.
