Today, the second round of rain and snow weather process in 2020 will officially start. It is predicted that there will be a rain and snow process in the east of Qinghai Tibet Plateau, Northwest China, North China and South China on September 12. The boundary between rain and snow is located in Qinling Mountains to the West and north of Huanghuai river. In the north, it is generally small to moderate snow, while in the south of Shaanxi and the west of Huanghuai River, it is heavy snow. In the south of the boundary, it is generally light rain, with moderate rain and local heavy rain from the middle and lower reaches of the Yangtze River to the north of South China The required time period will appear on September 11.

Specifically, from todays 08:00 to tomorrows 08:00, there are small to moderate snow or sleet in the northern mountainous areas of Xinjiang and parts of the areas along Tianshan Mountains, most of the Qinghai Tibet Plateau, the Middle East of the northwest region, the north of Jianghan, the northwest of Huanghuai, etc., among which, there are heavy snow (5-9mm) in parts of the south of Tibet, the south of Qinghai, etc. In the south of Huanghuai River, the south of Jianghuai River, the south of Jianghan River, the north and west of Jiangnan, the east of Southwest China, and the north and middle of South China, there are small to moderate rain, and local heavy rain (25-45mm). There are 4-5 levels of wind in the Middle East of Inner Mongolia, Liaodong Peninsula, Shandong Peninsula and other places.

From 08 a.m. on January 10th to 08 a.m. on 11, there are small to medium snow or sleet in the northern mountainous area of Xinjiang and some areas along Tianshan Mountain, northwest of Heilongjiang, northeast of Inner Mongolia, east of northwest, east of Tibet, southwest of North China and west of Jianghan.

There are small to moderate rain in the southeast of Huanghuai, Jianghuai, Jiangnan, east of Jianghan, South China, East and south of Yunnan, and south of Guizhou.

Generally speaking, the range and intensity of the precipitation process from September to December are lower than that of the previous round of rain and snow weather process. This is mainly because the South Branch trough is relatively weak and the conditions of water vapor transport and dynamic uplift are not as good as that of May to July. However, the good news is that in South China, where the weather drought is still serious, there will also be rainfall on November 12, which can play a positive role in easing the local drought and forest fire risk.

Push ({ID: u5811557, container: ssp_, async: true});))); in terms of temperature, in the first two days, the temperature in Jiangnan and other places in China was abnormally high, many places broke the warmest record in January, and some places even warmed up the level of summer, which surprised many netizens. But false summer is always false summer. Since July 7, under the combined effect of cold air and rainy weather, the temperature in many places has dropped sharply, with a drop of more than 10 u2103. It is expected that in the next few days, the temperature in Jiangnan will basically return to normal level. In addition, the temperature in Huanghuai and Jianghuai areas will continue to be low in the next three days. The highest temperature in Hefei, Wuhan, Nanjing and other places in the daytime is expected to reach a new low after winter. Finally, it is worth mentioning that today and tomorrow, the atmospheric diffusion conditions in the south central part of North China, the northern part of the Huang Huai River, the Fen Wei plain and other places gradually turn worse, with light to medium haze weather, and the local public travel needs to do a good job of protection in advance.
