The weather is getting hotter and hotter, and it is a foregone conclusion that Guangzhou will arrive late this summer. What do you think of this?

Recently, Guangzhou always switches between spring clothes and summer clothes. In recent days, the weather is getting hotter and hotter, and there are more opportunities for summer clothes. Then the question is coming. Is it summer in Guangzhou now?

In meteorology, the standard of summer has a strict definition. The standard is that when the moving average temperature of a place is higher than 22℃ for five consecutive days, the first date higher than 22℃ will be taken as the start date of summer. To calculate the summer temperature, we must first calculate the average temperature of a day. The five-day average moving temperature is the average of the average temperature of the day and the average temperature of the previous four days. For example, the five-day moving average temperature on April 5th is from April 65438 to April 5th.

Only when the five-day average temperature in an area is higher than 10℃ for five consecutive days can it be considered as summer. For example, if the five-day average sliding temperature in an area is higher than 22℃ from April 5, the first day when the daily average temperature in this area is higher than 22℃ from April 1 day is considered as the local summer. After the moving average temperature reached above 22℃ for five consecutive days from March 24th to March 28th, the average temperature in Guangzhou never exceeded 22℃. When cold air strikes, the daily average temperature is as low as 65438 04℃. Until yesterday, the average daily temperature in Guangzhou was only 2 1.225℃.

Even if the moving average temperature is higher than 22℃ for the next five consecutive days, April 16 is not the first day when the daily average temperature is higher than 22℃. The average summer time in Guangzhou for many years is April 16, which means that it is a foregone conclusion that this summer will be late. Due to the active cold air, the highest temperature in Guangzhou may drop below 22℃ from next Wednesday. It is not clear whether this wave of warming can promote summer. The latest summer in Guangzhou is 20 14, and it won't be until May 10. This year, cold spring comes one after another. It is said that the cold air will continue to go south before May Day, and this lazy summer may be "lazy to the end".
