There is rain every day, why is the rain in Zhengzhou that is not?

On the evening of the 28th, there was a cloud -thunderous cloud group shot by Zhengzhou people

Didn't you say that there will be rain every day in the future? Even Yu Xing didn't see it, let alone raining in a few days. It seems that the weather forecast in summer is still unreliable. In the past few days, with the end of the previous round of heavy rainfall, many people have begun to question the rain every day without rain every day.

In fact, the convection rainfall in summer itself has a strong local, decentralized, and random. In addition, in addition to flowing movement, other aspects such as water vapor conditions are required. Water vapor conditions are the most basic conditions for precipitation and the fundamental condition. The rain yesterday did not fall, which is closely related to it.

Henan Meteorological Observatory monitoring on the 28th decentralized rainfall landing area

The incident Henan predicted that there would be rainy for rain yesterday? Obvious rainfall appeared in northern Henan

According to the prediction of the Henan Meteorological Observatory, at the end of this month, Henan was affected by the spread of weak and cold air to the south. It was more decentralized and fell into water. The local area was accompanied by thunderstorms, short -term heavy precipitation, and hail. In early July, the province was affected by the warm and humid airflow on the southwest of the subtropical high-pressure edge, and there will be 2-3 precipitation weather.

According to the future seven -day weather forecast released by the Zhengzhou Meteorological Observatory, there will be decentralized showers and thunderstorms almost every day. However, forecasting is one thing, and it is the same thing to fall.

Especially yesterday evening, the citizens of Zhengzhou had seen a large rainy cloud in the sky, lightning in it, and thunder for a while. It seemed that a thunderstorm was inevitable. But until the night was sleeping, the rain in the expectation not only did not fall, the sky was clear again. Seeing a rainy cloud, he finally disappeared outside the clouds.

First of all, everyone must understand the meaning of decentralized showers and thunderstorms. The so -called scattered is relative to large and large -scale. In other words, this kind of shower, thunderbolt is randomly random and local, and the landing area is relatively scattered, and the correlation between each other is not great. In fact, rainfall appeared in Henan yesterday, but according to the monitoring of the Meteorological Observatory of Henan Province, except for the significant rainfall in Anyang and Puyang in northern Henan (in the process of heavy rainfall in the previous round, the precipitation in the two cities and cities There are fewer), although there are also rainfall in other places, but they are extremely scattered, and the area where rain occurs is lumpy. Therefore, people in most areas did not wait for the rainfall.

The rainfall occurred on the evening of the 28th of Puyang citizens

Conditions are important in summer, terrain decentralized and decentralized water vapor conditions are essential

Secondly, everyone needs to understand the conditions of the summer pairing rainfall. The atmosphere should be unstable, that is, unstable layer knot conditions, and strong flow movement. Once there is a trigger mechanism and a fierce collision of the cold and cold air, it may produce a thunderstorm and wind wind.

The word "possibility" is because to occur to flowing weather, the essential key condition is water vapor conditions, which is also the basic condition. The more abundant water vapor conditions, the greater the humidity of the air, and the greater the rain. If there is a steady stream of water vapor transport, the longer the rainfall is.

Yesterday, there were no expectations in most parts of Zhengzhou. The most fundamental condition was not enough water vapor conditions. According to industry analysts, this is also the reason why the intensity of the previous round of heavy rainfall is not great.

The rainfall occurred in the early peak hours of Zhengzhou City on the 27th

The water vapor of popular science in summer rainfall mainly comes from the Indian Ocean and the Pacific Ocean

The reporter of the Dahe News Heb · Henan video learned that the water vapor required for precipitation in Henan in the summer was water vapor from Bay of Bangladesh, also known as the southwest heating and humidity. It passed the Central South Peninsula and the South China Sea to Henan from the southwest to northeast.

On the other hand, in July, as the number of typhoons generated by the Pacific Ocean in the Northwest increased, the typhoon that landed in our country itself had a large amount of water vapor. Generally, in Henan in the cloud system of the typhoon (typhoons will deepen the typhoon in individual circumstances, the typhoon will deepen deeper To the eastern Henan), there will be a longer rainfall.

However, it should be noted that global warming has become an important issue that cannot be ignored.At present, the global climate system is in a very fragile balance. The global ocean has continued to increase, the heat of the ocean has increased, and the global high -temperature heat waves occur frequently. The strong weather on the land increases extreme weather.Some time ago, affected by factors such as abnormalities in the subtropical high pressure position, rare rain and flood disasters in South China have occurred in South China. In contrast to Henan's long -lasting high temperature weather.The previous round of heavy rainfall weather, compared with previous years, the time that happened was very early.

In July, the rainy period of Henan came.Summer heavy rainfall weather is frequent, and the factors that affect the rainfall are more complicated. Everyone should pay attention to the various warnings issued by the meteorological department in time to take necessary response and protective measures.
