Climatic characteristics of Beijing

The temperature rises rapidly, the temperature difference between day and night is large, and it is dry and windy. In spring, with the gradual increase of the sun's altitude angle, the daylight time is prolonged, and the heat obtained on the ground exceeds the expenditure, so the temperature rises rapidly. The monthly average temperature can be increased by 9-6℃, the average temperature is 4.5℃ in March and 13. 1℃ in April. The daytime temperature is high, the nighttime radiation cooling is strong, and the temperature is low, which is the season with the largest temperature difference between day and night. The average daily temperature difference is 12- 14℃, and the maximum daily temperature difference is 16.8℃.

In addition, cold air activities are still very frequent in spring, and due to the severe cooling, there is "late spring cold" weather, which is easy to form late frost. There are many windy days, and the windy days of magnitude 8 or above account for 40% of the total days of the year. When strong winds appear, they are often accompanied by floating dust, sand blowing and sandstorm weather. The scarcity of precipitation in spring aggravated the spring drought, which is called "ten years and nine spring droughts".
