The extended version of the dog days and consecutive hot days will start next week, and Shanghai will welcome a wave of "hot news": the weather is entering a small summer in the Ming Dynasty | Shanghai | Extended version
Shanghai friends will welcome a wave of "hot news".
Tomorrow, Shanghai will enter the "Xiaoshu" solar term, and the weather will also be very "Xiaoshu". The highest temperature will still exceed the 35 ℃ high temperature line, and it will be hot and rainy. Tomorrow night, the rain will become more noticeable. It is recommended to keep a clear umbrella when traveling.
During the "Xiaoshu" period, the plum rain in Shencheng comes to an end, and summer is approaching. According to meteorological data, Shanghai experiences an average of around 5 days of high temperatures above 35 ℃ throughout the year, sometimes accompanied by sustained heatwaves.
What is a high temperature heat wave? Simply put, it refers to the occurrence of hot weather for more than three consecutive days. From the current forecast, it appears that the high temperature KPI for "Xiaoshu" will meet the standard next week.
The Shanghai center Meteorological Observatory predicts that the highest temperature in Shencheng will remain between 35 ℃ and 36 ℃ from next Tuesday to Saturday, which means that the high temperature heat wave is coming.
Another "hot news" is that Shencheng will officially enter the ambush next Tuesday. This year is still an extended version of the dog days, lasting for 40 days.
Do you still remember the extended version of the dog days in Shanghai last year? That's really numbing from the heat. Nearly 90% of the 40 summer days are high temperatures of 35 ℃ or above.
Will the extended version of the dog days really get hotter?
The reporter learned from meteorological experts that the "extended version" of the dog days is actually very common, appearing in 2016, 2018, 2020, and 2022, which is 10 days more than the "regular version" of 30 days. The main reason is that the midsummer season is twice as long as usual, lasting up to 20 days.
Long time does not necessarily mean high heat. Meteorological experts say that the extension of the mid summer is just a matter of date arrangement and does not necessarily mean that the extended version of the mid summer will be hot for 20 days.
In meteorology, the number of days with high temperatures is not necessarily related to the duration of the hot weather, but is determined by factors such as the atmospheric circulation background, the position, intensity, and control time of the subtropical high pressure. If both cold air and typhoons are inactive, the stronger the subtropical high pressure and the longer it stays, the hotter the weather will be.
This year, the reason why Shanghai encounters consecutive hot days as soon as it enters the summer is actually due to the influence of the subtropical high pressure. Starting from next Tuesday, with the westward extension and strengthening of the subtropical high pressure, Shanghai will experience a series of high temperatures.
From a national perspective, Shanghai is not yet considered hot. According to the monitoring of the Central Meteorological Observatory, today's high temperatures will be divided into two large areas: north and south. Beijing, Tianjin, Hebei, Shandong, Henan, Xinjiang and other areas will continue to experience high temperatures, with local temperatures reaching up to 40 ℃. At the same time, high temperatures in Guangxi, Guangdong, Fujian, Hunan, Jiangxi and other areas will also increase. In the next week, Sichuan Basin, Jiangnan, and South China will also experience phased high temperature weather, with daily maximum temperatures reaching 37 ℃ to 39 ℃ in central Hunan, central Jiangxi, Fujian, and central southern Zhejiang.
