Above 44 degrees in Hebei, the strongest rainfall in the north came. How is this cold air formed?

Since the flood season in the north, the strongest rainfall has hit. After experiencing an extremely hot climate, all parts of the northern region will enter a strong precipitation mode. More than ten provinces and regions in the northern region will be eroded by heavy rain and torrential rain, and there will be short-term lightning and strong precipitation in some areas. The heavy rainfall will occur in Hebei, Shandong, Liaoning, Qinghai, Ningxia, Gansu, Inner Mongolia, Jilin, Shaanxi and Henan. The relevant departments must do a good job in defense to prevent losses.

The heavy rainfall is closely related to the subtropical high anomaly, which is mainly affected by several weather systems such as subtropical high, high-altitude trough and surface cyclone. The heavy rainfall also showed great intensity and fast movement, mainly focusing on the education of convection. At the same time, it is the strongest rainfall since the flood season in the north. All localities should be alert to the harm caused by heavy rain, and this heavy rainfall will also have a great impact. Therefore, it is necessary to pay attention to the influence of geological disasters such as mountain torrents and the risks brought by some local river floods in the heavy rainfall areas in the north.

The heavy rainfall in the north is also very strong in a large range, but at present, the north has not entered the main flood season, so this large-scale heavy rainfall is relatively rare, with small to moderate rainfall, accompanied by convective weather such as thunderstorms and strong winds. This heavy rainfall also caused the soil to be saturated with water, so we need to be alert to natural disasters such as landslides, and at the same time, we should stay away from some areas with high risk of meteorological disasters, do a good job of drainage, and pay attention to avoiding heavy rainfall periods to protect personal safety.

After the rainstorm, we must do a good job in defense. First of all, people must know the local climate and precipitation warning information. People in high-risk areas had better not go out and wade by car. If you must go out, you must go hand in hand, and you must detour when you encounter water on the road. Drivers should pay attention to driving safety. If you deposit water in your account, you must cut off the power supply. Farmers must improve the flood control ability of farmland and prevent food crops from being damaged. In addition, people at risk of landslides and mudslides must evacuate as soon as possible.
