It is predicted that in the next week, heavy rainfall will also occur in the eastern part of Northwest China, central and eastern Inner Mongolia, North China, and Northeast China. After the high temperature, there will be heavy rain. Please keep this guide for surviving the flood safely! What disasters will heavy rain cause?

1. Why is there always heavy rain after high temperatures?

Sustained high temperatures in summer are generally due to the "subtropical high pressure" controlling the area. When controlled by the "subtropical high pressure", generally weak cold air cannot enter, so it will continue to be sunny and hot with high temperatures. But when there is stronger cold air in the upstream moving southward, the subtropical high pressure will swing or retreat, and the temperature will be higher. When strong cold air meets the original warm air mass, strong rainfall will occur.

2. Frequent extreme weather

The climate phenomena in the early stages of climate warming remind us. , cities and human settlements must prepare for these extreme weather events that will occur more frequently in the future, because this is a major trend. If populated areas are not prepared in advance for these climate disasters, these extreme weather events may occur. It turns into a big disaster. In the early stage, there are more small-scale and low-level occurrences of various extreme weather, such as storms, tornadoes, heavy rains, high temperatures and droughts, etc. This is caused by the continuous increase of atmospheric energy and ocean water vapor. ?

3. What disasters will be caused by heavy rain? The period after heavy rain is also a period of high incidence of diseases. Due to the humid weather, bacteria are easy to breed. In addition, after floods, water sources are extremely easy to be contaminated, and food is easy to spoil. Some people and rescue workers have been soaked in sewage for a long time. People are exposed to sewage for a very long time, so various infectious diseases are easily spread. After heavy rain, all kinds of sludge and debris on the ground gather together, and the quality of the water will be greatly affected. Therefore, cooked food and food soaked in rain cannot be eaten again. Vegetables and fruits must also be fully washed or peeled before eating. Pay special attention to strictly avoid contact with various polluted water bodies and avoid drinking raw food. Water, especially in rural areas with open pits

Postscript: The earth’s climate system is like the human body. When you have a fever, the system will automatically start the cooling process, melt the glaciers, heat up the sea water, and increase the evaporation of water vapor? But? When the fever exceeds a certain level, if you don't take medicine, the earth's own regulatory system will malfunction and get out of control. You know the consequences.
