Introduction: As we all know, in July, Henan Province was hit by heavy rain, especially in Zhengzhou and Xinxiang, where many people were trapped and property and material losses were huge. The 720 rainstorm brought profound disasters to the people of Henan, and at the same time, it got help from all walks of life, and other provinces also quickly launched rescue forces. All walks of life have donated money and materials to Zhengzhou area. Let's take a look with Bian Xiao. What's the difference between this round of heavy rainfall in Henan and the 720 rainstorm? How do experts interpret this?

I. Summer rainstorm

Influenced by the latitude and temperature zone in China, there will be a strong rainy season every summer in China. As we all know, summer is the rainy season in our country, and severe drought usually occurs in spring and autumn. Most coastal areas in China belong to monsoon climate, while inland areas belong to continental climate. A few years ago, droughts and floods often occurred in coastal areas of China. This very rare drought and flood disaster happened in central China. Henan is located in the Central Plains, and it is also an important city for Belt and Road construction.

Second, the 720 rainstorm

The 720 rainstorm in Zhengzhou area, especially on Line 5, has caused great property and life safety hazards. Experts believe that the 720 rainstorm was mainly caused by typhoon fireworks. Although the typhoon fireworks are located in the inland areas of China, they remotely control the rainstorm in Henan. A lot of Pacific water vapor reaches inland from the sea, which is influenced by Henan topography, causing serious rainstorms in Zhengzhou and Xinxiang areas of Henan Province. Because the typhoon moves very slowly, it will lead to a long rainfall duration.

Third, this round of rainfall.

Affected by the severe warning of the July 20 rainstorm, Zhengzhou citizens put their cars on the viaduct very early to prevent the rain from soaking the cars. In the face of this rainstorm, emergency response to flood control has been launched in various parts of Henan Province. In Zhengzhou, where there is heavy rainfall, the officers and men of the armed police are ready and various flood control measures have been put in place. The rainstorm has short duration, less rainfall and short rain period.
