Why does it rain in Henan? Why does it rain in Henan?

1, typhoon influence. Although the distance of Typhoon Fireworks is 0/000 km from China/KLOC-,it has controlled the rainstorm in Henan province remotely. 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.

2. Topographic reasons. 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.

3. 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.
