Large-scale high temperature weather in the north has come back. Why is Henan a high temperature center?
The high temperature in Henan remains high.
As can be seen from the latest high temperature forecast map, Henan is now the main high temperature area, and almost all of the province is around 30 degrees. At the same time, some parts of Hebei and northern Anhui also experienced high temperature of 35 to 37 degrees, and the temperatures in these three provinces were obvious. Among them, Henan is the most distributed area around 40 degrees, and it is also the area with relatively high temperature except Xinjiang. Of course, Yunnan, Hainan and other places also have a small range of high temperature areas, which are relatively not as high as Henan.
Let's briefly explain a city, such as Yongcheng, Henan. According to the data of the Central Meteorological Observatory, on June 2, the temperature in this area exceeded the expected maximum of 35 degrees, so the temperature was very explosive. By June 3, the high temperature will increase, the strongest may reach 37 degrees, and then there will be 38 degrees and other high temperatures, which obviously shows that Yongcheng, Henan Province is basically? Baking? Mode, the temperature is really too high. Of course, we can see from the high temperature forecast map that Henan is now a high temperature area in the northern region.
Why is the high temperature in Henan so strong?
It can be seen from the development of high and low pressure system that Henan now belongs to the intersection of high and low pressure and rainfall, so the weather is very complicated. At the same time, we can see that the subtropical high in the northwest Pacific is very fierce this year and has obviously entered the land area of China. Level two? The influence of high pressure has extended to? Jiangsu, Zhejiang and Shanghai? Area, which clearly shows that the warm current has basically occupied most areas, and Henan is just the main interval of the three airflow modes, so the weather in Henan is more complicated now.
At the same time, according to the conventional situation, this is also an extreme weather situation. There are more and more climate anomalies on the earth itself, so this is not limited to the current climate situation in Henan. On a global scale, there is widespread high temperature in the Arctic, and now Henan may be outside the affected area. Judging from the temporary forecast of the Central Meteorological Observatory, the situation of less rain in Henan will continue to develop, and the time may be a little longer.
When does it rain in Henan?
No rainfall development was observed in Henan in early June, but a wave of rainfall was observed in Henan in mid-June, mainly concentrated in the southern region, and the time period was June10-June1. There will be moderate to heavy rain in half of the province and heavy rain in some areas, so there is basically no hope that it will not rain in the first ten days, and it will not appear until mid-June. After this period of time, that is, the maximum rainfall is 1 day, and a wide range of sunny days will return.
This isn't it? It didn't rain in Henan in May, and it didn't rain in early June. In mid-June, it is predicted that there may be about 1 day of rainfall, which is really less in most areas. At the same time, judging from the drought monitoring in Henan, there has been a large-scale drought, and some areas still appear? Extreme drought? . This is obviously a lack of rain, and friends in Henan need to continue to take precautions? Drought? The problem of development, it seems that the rain will continue to be less in a short time.
Generally speaking, the climate is really changeable this year. The unusually high temperature in early May was also in the northern region. At the same time, the El Niñ o phenomenon developed this year, and the subtropical high in the northwest Pacific was strong, which seriously affected the uneven development of rainwater, with more north and south ends and a slight decrease. But on the whole, this year's rain may be more serious than drought, so there has been a complex climate model, and everyone should always do a good job of climate impact.
