一、成都气候特征 二、气候要素(1990年—2005年) 三、成都四季气候特点: Located in the bordering areas of the Sichuan northwest highland and Sichuan basin, Chengdu has its own climatic features.

The annual average temperature is around 16.4 degree. Even in the cold January, the average temperature is some 5.degrees. It rarely snows.

Third, there is not much precipitation in winter and spring while it is affluent in summer and autumn with the total precipitation volume of 1,124 centimeters. And this figure is comparatively stable, the ratio of the year with most rainfall and the year with least precipitation being 2:1. Fourth, the climatic elements of light, water and heat almost occur in the same season, which is a very favorable combination to the growth and propagation of the vegetation. Fifth, the wind speed is low. On the plain and in the mountainous areas, the normal speed of wind is around 1 to 1.5 meters per minute. The total sunshine hours average 1,042 to 1412 each year. |
