The Turpan Heat Day has reached 39 days! How does the national temperature develop after the summer solstice? Expert analysis shows that the number of days during the 40 day period of the three hottest days | three hottest days | high temperatures
Today marks the official end of the 40 day three dog days this year. Compared to last year, what is the temperature of the three hottest days in China this year? How will the temperature develop after the summer solstice? Take a look at the analysis of meteorological experts.
It is said that the heat is in the summer heat. Looking back at the extended version of the 40 day summer heat that just ended this year, it can be said that the heat in many places is even higher than usual. Let's take a look at many parts of the country, especially in most northern regions, where the average temperature is generally one to two degrees Celsius higher, and in many provinces, regions, and cities, the heat is among the top during the same period. It can be seen that Xinjiang ranks as the hottest region of the same period, and in addition, Shanxi, Hebei, and other places, the heat can also be ranked second or third in history.
In addition to the average high temperature, there are also many days of high temperature. During the 40 day dog days, it can be seen that many places in the northwest have reached 20 or even 30 days of high temperature, such as Turpan in Xinjiang, which has a total of 39 days of high temperature.
In addition, in Ejina Banner and Dunhuang in Gansu Province, the total number of days with high temperatures is also the highest during the same period. In addition, the North China Plain has also experienced unusually hot dog days. From the perspective of the anomaly of high temperature days, in some areas of Tianjin, Hebei, and Shanxi, the number of high temperature days is about 5-10 more than usual. For example, in Beijing and Shijiazhuang, during the three hottest periods of this year, the number of high temperature days is even close to the average total number of high temperature days throughout the year.
Moreover, the North China region is not only hot during the three fu periods, but also extremely hot before the onset of the fu period. It can be seen that the number of days with high temperatures during the three fu periods actually accounts for only about one-third of this year's high temperature season. After the three fu periods, the total number of days with high temperatures in Beijing and Shijiazhuang this year has reached 34 and 42, respectively, which are both the years with the highest temperatures in history.
Usually, after the three dog days, the high temperature weather in northern regions will rapidly decrease. It can be seen that in the upcoming Chushu solar term and beyond, the probability of high temperatures occurring in many northern regions is already very low, about less than 5%. In the later stage of the southern region, there will continue to be high temperatures, such as in the Jiangnan and South China regions, where nearly 20% of the high temperatures will continue to occur. For example, in South China, there are usually records of the latest high temperatures occurring in September or even early October.
Let's take a look at the next few days of this year. With the dominant subtropical high pressure, its main body will gradually retreat to the sea. Therefore, for China's land, the high temperature weather will be significantly reduced. Therefore, in the next three days, it can be seen that whether in the south or in Xinjiang, the high temperature weather only shows a small distribution, and there are not many high temperatures.
In addition, in areas that have already bid farewell to the hot season, such as the northern part of North China and some parts of Northeast China, the highest temperature will gradually drop to below 30 ℃, and there is already a feeling of cool autumn. In addition, we also pay attention to the fact that here in Xinjiang, such as the Turpan Basin, high temperature weather will continue to occur in the next four or five days, so we need to pay attention to heatstroke prevention and cooling.
