National Climate Center: 2 to 3 tropical cyclones (typhoons) will make landfall in China in the next month. Precipitation in China | year-round | China
"Seven down and eight up" is one of the important stages of China's main flood season. During this period, the north entered the main rainy season; At the same time, typhoon activity in the South China Sea and Western Pacific has entered an active period, and coastal areas are susceptible to typhoon precipitation and storm surges. The National Climate Center predicts that China will experience a pattern of both drought and flood during the "Seven Down and Eight Up" period this year. The specific prediction conclusions are as follows:
The eastern part of the Songhua River Basin and the eastern part of the Liaohe River Basin may experience severe flood conditions
It is expected that during the "Seven Down and Eight Up" period in 2023, the precipitation in the eastern part of the Songhua River Basin and the eastern part of the Liaohe River Basin will be more than 20% higher than the same period in normal years, and there may be severe floods and waterlogging disasters; The precipitation in the west of Songhua River basin, Nenjiang River basin, the west of Liaohe River basin, the east of Haihe River basin, the east of Huaihe River basin, the lower reaches of Yangtze River basin, the Taihu Lake Lake basin and the Pearl River basin is more than 10% to 20%, so it is necessary to pay attention to the local flood disaster that may be caused by the periodic heavy precipitation process; The precipitation in the western part of the Haihe River Basin, the Yellow River Basin, the western part of the Huai River Basin, and the upper and middle reaches of the Yangtze River Basin is close to the same period as usual, with a decrease of 10-20%.
There is a high possibility of high-temperature heatwaves occurring in most parts of North China, South East China, Central South China, and other regions
It is expected that during the "Seven Down and Eight Up" period, except for the eastern part of Northeast China where the temperature is 0.5 to 1 ℃ lower than the same period of the year, most other regions of China will have temperatures close to the same period of the year but slightly higher, with temperatures in southeastern China, northwestern China, Xinjiang and other regions slightly higher by 1 to 2 ℃; Most parts of North China, southern and eastern China, central and southern China, Xinjiang, and other regions have a higher number of high-temperature days compared to the same period throughout the year, and there is a higher possibility of periodic high-temperature heatwaves.
It is expected that during the "Seven Down and Eight Up" period, there will be 2 to 3 tropical cyclones landing in China, with an average intensity that is relatively strong. The main path will be westward and northwestward, mainly affecting the southern and southeastern coasts.
