Heavy rainfall occurred in many places in Sichuan, and more than 13,7 people moved to avoid danger in advance. How long will heavy rainfall last?
The rainstorm in Sichuan has affected more than 3,5 people in Chengdu, Deyang, Mianyang and other places, and more than 13,7 people have moved to take refuge in advance. The Sichuan Meteorological Observatory issued a blue rainstorm warning. After the early warning was issued, Sichuan Province responded quickly and made careful arrangements. Sichuan Provincial Prevention and Control Office issued risk warnings to cities (states) and provincial prevention and control office members overnight, organized 6 cities (states) and provincial-level national comprehensive fire rescue teams in rainy areas to hold special dispatching meetings, and continued to conduct rolling dispatching and spot checks on 12 county prevention offices, 6 towns (streets) and 3 key enterprises. We will continue to pay close attention to the rain and flood situation, strengthen consultation, judgment and early warning of all kinds of disastrous weather, promptly and decisively transfer the affected people and carry out emergency rescue and disaster relief.
The rainfall process in Sichuan Basin will continue for about a week, and the subtropical high is stable, and the water vapor on the west side of the subtropical high is continuously transported to Sichuan Basin. As a result, the rainfall intensity is large, the central areas of heavy rainfall overlap, and the accumulated rainfall is large. The soil moisture in central and northern Sichuan is close to saturation, the hidden danger points of geological disasters are dense, and the geological environment is fragile, which is prone to landslides and mudslides. Recently, people feel as if there are only two kinds of weather, either sun exposure or heavy rain, which makes the weather so violent.
The risk of mountain torrents and geological disasters in the western Sichuan Plateau and the western Sichuan Basin will remain high, so it is necessary to do a good job in disaster prevention. Under the control of subtropical high, downward flow is prevalent, and the Sichuan Basin is affected by subtropical high and superimposed with topographic factors. The air convection in the basin is weak, which makes heat accumulate, and the southerly wind leads to increased humidity and unbearable sultry weather. Rainfall is still mainly concentrated in the north. There will be scattered heavy rainfall in the west of Sichuan Basin, the east of northwest China, Huanghuai and Northeast China, and there will be heavy rain in the northwest of Sichuan Basin. ?
