Where will it rain heavily in July? If Typhoon No.3 forms, will it have a greater impact?
Where is the heavy rainfall mainly concentrated in the north and south?
The recent rainfall in the south can be said to be continuous and developing wave after wave. Today, the rainfall in the south is far away from the Yangtze River basin and transferred to Fujian, Jiangxi, Guizhou, Guangxi and other places. The area with the strongest rainfall is mainly concentrated in Fujian, with 1 280mm rainstorm point. Therefore, the Central Meteorological Observatory also continued to issue an orange rainstorm warning.
Of course, rainfall mainly refers to the above-mentioned areas, and there is still a lot of rainfall in the northern region, mainly concentrated in North China, in which the rainfall in Beijing, Tianjin and Hebei is obvious, and there are 70 mm rainstorm areas in some areas. Although the scope is not large, the climatic conditions in the surrounding areas can basically be alleviated. This is a rainfall on July 9, and by July 10, the rain belt fluctuated.
According to the forecast, if the rainfall moves south, it will move north, but the overall scope and intensity of heavy rainfall will be reduced, including heavy rain or rainstorm in parts of 6 provinces such as southeastern Hubei and northern Hunan.
From the forecast chart, we can see that rainfall? Trident? Basically formed, mainly divided into three waves, one in Tibet, Yunnan and other places, one in Sichuan, Shaanxi and Gansu. Then there was a wave in Jiangxi, Hubei and Hunan. Of course, the heaviest rainfall is near the Yangtze River basin. Friends in Hubei need to pay attention. It can be said that the rain has stopped now. According to the trend, new rain is coming again. And the intensity is not low, and there is also a heavy rainstorm point of 120 mm, followed by Jiangxi with little change, and there are still two heavy rainstorm points of150 mm.
On July 1 1 day, a heavy rain belt was formed in the northern part of the Yangtze River Basin, with heavy rain or rainstorm in parts of seven provinces, including central and northern Jiangsu, southeastern Henan, central and northern Anhui, northern and southwestern Hubei, northern and southwestern Chongqing, southeastern Sichuan and northwestern Guangxi.
According to the forecast map, heavy rainfall develops in most areas such as Anhui, Henan and Jiangsu, with the strongest rainfall 180mm. So a new round of rainfall restart has basically become a foregone conclusion. Of course, it can also be seen from the medium-term weather conditions that the rainfall will basically not stop in early July, so in the next ten days, the rainfall in Guizhou and other places in the middle and lower reaches of the Yangtze River will continue to be excessive.
Of course, when there is heavy rainfall, we should also pay attention to strong convective weather such as short-term heavy precipitation, thunderstorms or hail. This kind of convective weather is slightly more in North China and Northeast China, which is a common situation.
Is it possible for Typhoon No.3 to generate in July and affect precipitation?
In fact, there are still no typhoons in the South China Sea and the Pacific Northwest, so don't worry about the development of typhoons, which means that there is no possibility of typhoon No.3 for the time being. Of course, a few days ago, we saw a supercomputer simulating the development of tropical disturbance in the northwest Pacific and the possibility of typhoon, but now the data shows a very weak situation.
Therefore, it is necessary to continue to observe whether Typhoon No.3 will form this year, but there are many tropical disturbances and the performance is very obvious. Is this a possible typhoon? Phenomenon? . So next, we should not only pay attention to the development of rainfall in land areas, but also pay attention to the breeding of typhoon embryos in marine areas. At present, the main factor affecting the formation of typhoon may be subtropical high.
This year, the subtropical high in the northwest Pacific is very strong, which may be considered as an abnormal situation. Of course, if it stabilizes in the later period, typhoons will basically increase. There is no typhoon in the northwest Pacific today, but there are still many storms brewing and developing around the world.
According to the simulation data of supercomputer, there are two storm embryos in the world, 96E and 98L respectively. And named after tropical storms in the eastern Pacific? Christina. (Christina), the storm has intensified again. The maximum wind speed is 50KT, which is equivalent to 25m/s, and the central pressure is 998hpa. According to this intensity, it is not big, and then it continues to move to the north-north direction, and the intensity gradually increases.
On the whole, according to the path predicted by the US Weather Service, tropical storms? Christina. (Christina) It won't affect any region. It will be far away from the coast of the United States and Mexico, so just look at the data. China friends in these two regions don't have to worry.
The storm in the eastern Pacific has no effect, which is the general situation. As for the twin-storm embryos of 96E and 98L, the impact is not significant for the time being, and according to the trend, it is almost impossible to form a named storm, depending on the later changes. Now we are only concerned about the rain. China's rainfall lasts for a long time and covers a large area, and many places may have ushered in a rare rainfall development. Everyone should pay attention to flood control.
