Extreme weather is frequent! Rainstorm in Xining, Qinghai caused waterlogging in many places. Why is the waterlogging situation so serious?

Summer is a season with abundant rainfall, but for many inland cities and regions, there is no very serious flood disaster, because these areas are affected by weather factors and local conditions, there will be no very serious rainfall, but extreme weather has occurred in Xining and other areas in Qinghai, resulting in very serious rainy weather in these areas, and even serious waterlogging in many cities. The reason why these areas are so seriously waterlogged is that these areas are originally located in relatively low-lying areas. Because there are many mountains, most villages and cities are in some low-lying areas, which provides congenital conditions for waterlogging. Once it rains heavily for a long time, it is very prone to waterlogging. Therefore, some reasons for waterlogging in many places in Qinghai are influenced by local topography, which is also a major factor leading to waterlogging. Apart from the topography, the most important factor is that the local authorities have not prepared in advance for the treatment and solution of the whole heavy rainfall and waterlogging, because Qinghai is a very inland area in China, and there is basically no continuous heavy rainfall. Therefore, there are almost no solutions and measures to deal with heavy rainfall waterlogging in various regions of Qinghai, so in the face of unexpected situations, there will be some confusion, which will lead to such a serious waterlogging situation. On the other hand, there are weather factors. According to relevant data, almost all areas in Qinghai have experienced extreme weather. It can be said that the rainfall was very heavy and lasted for a long time, and there were even many heavy rains. In fact, in the face of such weather, some solutions are still reluctant, so it is inevitable that there will be more serious situations in the face of these heavy rainfall groups in the early stage, so the extreme weather faced by Qinghai is also the main reason why I am so serious.
