The rainstorm period in Beijing is from afternoon to night. Does it affect the evening rush hour?

The rainstorm period in Beijing is from afternoon to night, which will have a great impact on the evening peak to a certain extent.

? Recently, affected by global warming and subtropical high, heavy rain events have occurred frequently in the middle and lower reaches of the Yangtze River and North China. Because the subtropical high has been in a stable range this year, the amount of water vapor in the ocean has increased, and the cold air in the north has caused two air streams to meet, resulting in extreme weather with continuous heavy rainfall. With the passage of rainfall range, the current rainfall range has moved to Beijing, Hebei and other places, which has brought great influence to the local area.

The rainfall of rainstorm in Beijing is still increasing, and the rainstorm period is mainly concentrated from afternoon to night every day. Its main feature is its long duration. The main rainfall period is from afternoon to night every day, and the rainfall begins to decrease in August 13. During this period, the rainfall increased compared with previous years. The average rainfall in the city is between 40 and 80 mm, and the urban area is about 50 mm. During the rainfall, there are extreme weather such as thunderstorms and local strong winds. Rainfall affects the whole North China Plain.

The increase of rainfall and the untimely treatment of urban drainage system may actually lead to waterlogging. The amount of accumulated water from noon to night leads to road congestion, urban system paralysis, road traffic chaos, and traffic accidents may cause casualties. Such heavy rain will affect the attendance of employees and delay the operation of the company. At the same time, the pit in the heavy rainfall area will cause the danger of landslide and bridge collapse, and all kinds of hidden dangers will delay the evening peak and make the urban traffic more crowded.

The increase of rainfall leads to road water accumulation in some sections, and the occurrence of heavy rain is often accompanied by strong convective weather such as lightning and strong wind, which may affect the evening peak. The Beijing municipal government has made preparations for defense, publicized the first aid guide in various regions, and arranged corresponding rescue teams to prevent mudslides. Give support to areas with serious geological disasters such as house collapse.
