The official of China Weather Network announced the summer! According to the Beijing Meteorological Bureau, Beijing officially entered the summer threshold on May 24. Beijing entered the spring on March 15 this year, and the spring time was as long as 70 days. Beijingers enjoyed the longest spring time in nearly 10 years.
"Spring neck is short" is a saying in old Beijing, which means that the spring in Beijing is as short as the neck of a person. Before enjoying the beauty of spring, the hot summer is here. The year-round (1981-2010) time for Beijing to enter the spring is March 30, and the summer into May 19, the average length of spring is only 50 days.
However, Beijing ’s “spring neck” has become “giraffe” this year. Beijing entered the spring on March 15 this year, and it was obviously too early. It entered the summer on May 24 and was slightly late. The spring time is 70 days, which is more than the average of normal It took 20 days.
According to China Weather Network statistics, the longest spring in Beijing in the past 20 years appeared in 2006, with 74 days. This year and 2002 are tied for second place with 70 days, and this year is also the longest spring in the past 10 years.
This year's road to summer in Beijing can be described as ups and downs. On April 24, Beijing's temperature exceeded the 30 ℃ mark. By May 1, Beijing's temperature was approaching 35 ℃. The early days of May Day are full of summer scenes. The diligent residents have packed up their long sleeves, coats and other spring clothes in preparation for summer. Then the next thing is to keep looking for coats, collecting coats, looking for long sleeves, collecting long sleeves ...

After the "experience version" at the end of summer in early May, cold air activities in North China and Northeast China were frequent, and the temperature fluctuated significantly. The average temperature never reached the summer standard, which directly led to the rapid lengthening of Beijing's spring time.
Judgment of the summer standard in the climatic sense is extremely complicated. When the moving average temperature is greater than or equal to 22 ° C for 5 consecutive days, the first date in the corresponding temperature series greater than or equal to 22 ° C is taken as the summer start date. This is why the meteorological department will not announce the summer on the day of the summer, but will delay the confirmation for a few days.
The Beijing Meteorological Observatory predicts that in the coming week, the temperature in the Beijing area will continue to rise, and the daily maximum temperature will generally be maintained above 30 ° C. Summer in the capital has arrived, and the spring clothes of the friends can be safely put away this time. (Planning: Feng Wei Design: Li Yiyu Data Support: Hu Xiao Audit: Zhang Fangli Liu Wenjing)
