Is the heavy rain in Hebei caused by a typhoon?

Hebei Province’s heavy rains are closely related to Typhoon Dusuri.

When the remnant circulation of Typhoon Dusuri moves northward, a turbulent southeastern water vapor conveyor belt is formed between it and the subtropical high pressure on the east side, which continuously transports water vapor from the sea to the Hebei area. At the same time, the convergence and dynamic conditions between the typhoon's inverted trough and the main body are quite strong, coupled with the dynamic uplift of the windward slopes of the Taihang Mountains and Yanshan Mountains in Hebei, causing more water vapor to condense into rainwater.

In addition, the continental high pressure in the westerly belt in the north and the subtropical high in the east have combined, blocking the northward path of Typhoon Dusuri, causing the typhoon's low-pressure circulation to stay in Hebei for a long time, further intensifying precipitation. of extremeness.

This meteorological situation led to the occurrence of extremely heavy rains in Hebei Province. A large amount of water vapor is continuously transported to the Hebei area, coupled with strong convergence and dynamic conditions, causing a sharp increase in precipitation. The dynamic uplift of the windward slopes of the Taihang Mountains and Yanshan Mountains further promotes the condensation of water vapor into rainwater. The combination of the continental high pressure and the subtropical high in the westerly belt blocks the northward path of the typhoon, causing the typhoon's low-pressure circulation to stay in Hebei for a longer period of time, making the precipitation more sustained and intense.

Things to note when encountering heavy rain:

1. Pay attention to the weather forecast: Understand the weather forecast in advance, especially the reminders of possible heavy rain. Keep abreast of weather conditions in order to make appropriate arrangements and preparations.

2. Safety of the living environment: Ensure the safety of the living environment, such as checking the sealing performance of the roof, windows and doors to ensure that there are no leaks. Clean the drainage system outside the house and keep it clear.

3. Avoid wading areas: Avoid wading areas, especially avoid contact with floods, stagnant water or strong currents. If you must cross water, choose a safe route and use supports, such as handrails or ropes, if possible.

4. Avoid driving: Try to avoid driving in heavy rain conditions, especially heavy rainfall and strong winds. If you must drive, slow down, keep a safe distance, and avoid wading areas.
