Is it scary? The cold air is coming again. Are you still struggling with the final question of when Guangdong will enter autumn?

Tell you, Guangzhou is really autumn! ! !

According to the recent temperature changes, it can be preliminarily judged that Guangzhou entered autumn on June 65438+1October 2 1

Guangzhou experienced an autumn decline this year. According to the reporter's statistics, some time ago, due to the combined effect of cold air and typhoon, the temperature in Guangzhou plummeted, from the temperature to autumn. During the periods of 10, 13 and 17, the five-day moving average temperature in Guangzhou dropped to 2 1.4 1℃, which was 22℃ lower than the autumn temperature standard. The cold air that affected Guangzhou at that time was not too strong, just because the typhoon approached and brought rain, which doubled the chill. Therefore, after the combined action of cold air and typhoon, the temperature rose rapidly, and the 5-day moving average temperature rose above 22℃. The first time I tried to enter autumn this year, I failed.

But soon, as the weak cold air continued to supplement southward, the temperature in Yangcheng dropped again, and it fell below 22℃ on June 265438+1October 2 1 day. In the following days, although it was warm during the day, the average temperature never returned to above 22℃. Coupled with yesterday's cold air attack, although the cooling rate is not large, it further pushes the temperature down, and the autumn is more obvious.

It can be seen that from the preliminary judgment, Guangzhou has entered autumn in June 10 and June 2 1. According to the forecast, the next obvious cold air impact process may occur around 165438+ 10/0/4 ~16 with precipitation and cooling weather.

Dear friends, the weather is changeable. Add clothes in time to prevent colds.
