Who knows what the weather is like in Beijing in May and summer?

Spring: the temperature rises quickly, 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. It's windy Summer: Summer is hot and hot, and precipitation is concentrated, forming the same season of rain and heat. In summer, except in mountainous areas, the average monthly temperature in plain areas is above 24℃. Although the hottest month is not June, the extreme maximum temperature mostly occurs in June, and the extreme maximum temperature in June 196 1 day is 43.5℃.
