There is still heavy precipitation in Henan, Hebei and other places, and Hebei has issued three consecutive red warnings. Why is this wave of rain so strong?
According to the related information reported on the Internet, heavy rainfall occurred in Henan Province for several days, and extreme weather such as heavy rain and heavy rain occurred in most parts of Henan Province, resulting in heavy rain in nearly ten prefecture-level cities. The reason why this heavy rainfall is so strong is mainly related to our typhoon fireworks, because this season itself is the rainy season. Under the unstable atmospheric circulation, the subtropical high in the western Pacific is different from the high in the mainland.
It is precisely because they are maintained in two different areas, and then a waterway is formed when the subtropical high is abnormally northward. This waterway connects the typhoon fireworks with Henan and other areas. The existence of typhoon fireworks transported a lot of water vapor to Henan and other areas, which is also the reason why this heavy rainfall was so strong, and it also exceeded previous heavy rainfall. Mainly the existence of typhoon fireworks is equivalent to this.
To sum up, we can clearly know why there is heavy rainfall in Henan, Hebei and other areas, and why this wave of heavy rainfall is so strong. As the main reason, it is related to typhoon fireworks, and a water channel is formed between them. As a water pump, typhoon fireworks have been continuously draining water to Henan and other areas, and this is the result.
