Why is the rainstorm so heavy in Henan 202 1

Why is the rainstorm in Henan so heavy? Typhoon 202 1 ①, come back! Although Typhoon Fireworks is still 1000 km away from China, it has controlled the rainstorm in Henan province remotely. Under the guidance of "fireworks" and subtropical high-pressure airflow, a large amount of water vapor is continuously transported from the ocean to the land by the east wind, and it gathers into rain in Henan.

② Topographic reasons. After encountering Taihang Mountain and Funiu Mountain in Henan Province, the easterly airflow converged and expanded in front of the mountain, making the rainfall concentrated and strong.

③ The atmospheric circulation is stable and the rainfall lasts for a long time. At present, only when the typhoon "fireworks" approaches China, the circulation situation is adjusted and the water vapor source is cut off, can the rain in Henan stop.
