1, Typhoon Du Surui
Typhoon Du is the main cause of heavy rain in Beijing, Tianjin and Hebei. When Typhoon Du landed on the southeast coast of China, it collided with the subtropical high in the north due to the influence of the subtropical high, which led to the subtropical high being pushed to the north, and the typhoon system was resisted by the subtropical high. Under the guidance of the west side of the subtropical high, the typhoon gradually weakened but still carried a lot of water vapor northward.
Du remnants in the north continuously transported the water vapor accumulated at sea to North China, and formed a strong jet at the junction with the subtropical high, which provided sufficient sources for this large-scale and high-intensity rainfall.
2. typhoon khanun
There is also a typhoon "Kanu" generated in the Pacific Ocean, and its power is gradually increasing. Under the influence of typhoon khanun, a large amount of water vapor will also be transported to the north, further assisting the high-intensity rainfall in North China.
Matters needing attention in rainstorm days:
1, pay attention to lightning: rainstorm weather is often accompanied by lightning. In lightning weather, avoid outdoor activities and stay away from tall objects, such as trees and telephone poles.
2. Pay attention to the road conditions: Heavy rain may cause water and mud on the road surface, reducing driving safety. If you must drive, slow down, keep a safe distance and pay attention to the road signs.
3. Check the drainage system: ensure that the drainage system around the residence is unobstructed to prevent floods from flooding into the house.
4. Pay attention to weather warning: pay attention to weather warning and emergency notice in time to understand the latest meteorological situation and countermeasures.
5. Prepare emergency equipment: prepare emergency equipment, such as flashlights, spare batteries, emergency food and drinking water in case of emergency.
