Why did Henan become the national heavy rainfall center?

One is a typhoon. Although "Fireworks" is 1000 kilometers away from China, it remotely controls the rainstorm in Henan. Under the guidance of "fireworks" and subtropical high, a large amount of water vapor is continuously transported from the sea to the land through the east wind, and it gathers into rain in Henan.

The second is the terrain. After the easterly airflow meets Taihang Mountain and Funiu Mountain in Henan Province, it converges and rises in front of the mountain, resulting in concentrated rainfall range and stronger rainfall.

Third, the atmospheric circulation situation is stable, resulting in long rainfall duration. At present, only when the typhoon "Fireworks" is closer to China, the circulation situation will be adjusted, the source of water vapor will be cut off, and the rain in Henan will stop. At present, the main city of Zhengzhou is in the strongest period of this heavy rainfall. It is expected that the rain will weaken after this echo. However, according to the forecast, there will still be heavy rain to heavy rain in Zhengzhou today and tomorrow.

Influence of rainstorm in Henan Province

According to the data released by the National Meteorological Administration recently, there were four regional rainstorms in July. Among them, the extreme rainstorm weather in Henan has obvious influence, and many cities such as Zhengzhou and Xinxiang have serious waterlogging, which has a certain impact on local production and life.

According to reports, from the main data, the added value of industrial enterprises above designated size in Henan increased by 4.6% year-on-year in July, down 1 percentage point from last month. From June to July, Henan's investment in fixed assets increased by 5.8% year-on-year, down 2 percentage points from last month.
