The average temperature in Chengdu ranges from 1 to 12.

Chengdu 1 ~ 12 Average temperature 15.5 ~ 18.2℃.

1. Chengdu climate type:

Chengdu has a subtropical monsoon climate, characterized by early spring, hot summer, cool autumn and warm winter. The annual average temperature is 16℃, and the annual rainfall is about1000 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.

Second, the climate characteristics of Chengdu:

Mild climate, four distinct seasons, long frost-free period, abundant rainfall and little sunshine. Characteristics of wind direction in Chengdu: mostly static wind, northerly wind in June, July and August, and northeast wind in other months. Average precipitation in Chengdu: annual precipitation is about 9 18. mm Chengdu average temperature: annual average temperature 15.6 ~ 16.9℃ Chengdu.

General Situation of Four Seasons Climate in Chengdu The temperature rises earlier in spring, which is beneficial to the growth of trees and spring crops, but it is unstable and prone to continuous low temperature, which affects the timely sowing of crops in Da Chun.

Location, boundary and topography of Chengdu;

I. Location and background

Chengdu is located in the middle of Sichuan Province, in the west of Sichuan Basin, on the eastern edge of Qinghai-Tibet Plateau, bordering Deyang in the northeast, Ziyang in the southeast, Meishan in the south, Ya 'an in the southwest and Aba Tibetan and Qiang Autonomous Prefecture in the northwest. Geographical location is between east longitude 102 54' and north latitude 104 53' and north latitude 30 05' and north latitude 3 1 26'. ..

The land area of the whole city is 14335 square kilometers, and the urban area is 424 1.8 1 square kilometers, of which the built-up area is 93 1.58 square kilometers.

Second, the terrain.

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) in 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.
