Why does it rain heavily in Beijing?

The main reason for the rainstorm in Beijing is the influence of two typhoons.

One is the typhoon "Du Surui" from south to north. It landed in Zhejiang on July 29th and then moved to the northwest. It combines with the warm and humid airflow around the subtropical high and transports a lot of water vapor to North China. While the residual circulation of typhoon Dusuri moved northward, the subtropical high and continental high broke through to form a high-pressure dam and maintained it for a long time, blocking the forward route of Dusuri circulation from the east and north, so the extreme rainstorm ran aground.

The other is typhoon khanun from offshore zig zag, which approached China's coast on August 1 day, and also provided water vapor supplement for North China. Moreover, Beijing is located in the northwest edge of North China Plain, surrounded by mountains in the west and north, forming a natural barrier with an average elevation of 1 1,000 m. The southeast is a plain that moves down gradually. Facing the southeast monsoon, it triggers strong convective weather and leads to heavy rain in the piedmont area.

Matters needing attention in rainstorm weather:

1, close the doors and windows, stay away from the doors and windows, and avoid lightning hitting the room directly.

2. Unplug all the power in the home and try not to touch or get close to the metal pipes.

3. Don't use the shower. If lightning strikes a building, the current may be transmitted to people through the water flow, leading to an accident.

4. Take shelter from the rain on solid and high-lying buildings. Don't stay on rivers, water surfaces and trees. In case of lightning, it is not advisable to take shelter in the car.

5, pay attention to the wires around, pay attention to your feet. Take a detour where you see the rainstorm.

6. Avoid low-lying areas such as bridges and culverts; Stay away from outdoor billboards and temporary buildings.

7. If you get wet on the road, you should throw away the umbrella with metal and turn off your mobile phone.

8. When multiple vehicles are wading, they are not allowed to enter the water at the same time. When the car is wading, it should run smoothly at low speed.
