The process of heavy rainfall in the northern midsummer that many weather systems participate in
According to meteorological experts from China Weather Network, this round of heavy rainfall is a typical northern midsummer heavy rainfall process jointly participated by many weather systems such as subtropical high pressure, high-altitude trough, low vortex and ground cyclone. This rainfall process has a wide range and strong intensity. , The fast moving speed of the rain belt, the heavy rainfall is mainly convective rainfall, and there will be patches of heavy rain near the vortex.
This will be the strongest rainfall process in the north since the flood season, especially in the jet stream on the east and south sides of the low vortex, where the water vapor conditions are good, and we should be alert to the possibility of local extreme heavy rainfall.
