What are the reasons why meteorologists interpret the extremely heavy precipitation in Shanxi?
Heavy rainfall occurred in most areas of Shanxi. This process has the characteristics of large accumulated rainfall, long duration and extremely remarkable. The precipitation in the early stage was accompanied by lightning and strong convective weather, and the temperature dropped sharply and continuously in the later stage. The unusually strong western Pacific subtropical high first spread from west to north, and then remained stable in Huanghuai area. The low-value system of westerly belt has formed a stable circulation situation in Shanxi, which has caused long-term precipitation weather in Shanxi.
The low-level shear line convergence system has been maintained for a long time, and the precipitation echo repeatedly passes through the central part of Shanxi, superimposing the influence of the complex topography of Luliang Mountain and Taihang Mountain in Shanxi on the increase of precipitation in the easterly airflow, resulting in extremely heavy precipitation in the central part of Shanxi and the northern part of Linfen. Some rivers have high water levels and rich soil water content. We should attach great importance to and do a good job in the prevention and control of heavy precipitation and urban and rural floods, flash floods, mudslides, landslides and other heavy precipitation disasters. When a yellow or above flood warning is issued or a rainstorm occurs, it is suggested to adjust the travel plan to minimize going out.
if you live in dilapidated bungalows, low-lying courtyards, basements, piedmont plains or areas prone to geological disasters, you can take preventive measures, such as building fences, setting water baffles at the gate, configuring small pumps, preparing sandbags according to local conditions, and making preventive preparations in advance. When rainstorm or rainstorm or rainstorm occurs in a certain area, it will often lead to mountain torrents, reservoir dam collapse, river overflow, house collapse, farmland flooding and traffic communication interruption, which will bring serious harm to the national economy and people's lives and property.
Rainwater can't be released quickly, which leads to farmland water accumulation and soil water supersaturation, which will cause more geological disasters. When driving in rainy days, the line of sight is easy to blur, so it is best to slow down and try to keep a certain distance from the car in front. Don't get too close to the car, and don't overtake it frequently. Because of the rain, the road becomes slippery, which leads to the decrease of tire adhesion. If the vehicle speed is too fast, the braking distance in emergency is 2%-4% longer than that in good weather, the braking effect is obviously reduced and the probability of accidents is increased.
