How bad is the snowstorm weather in Zhengzhou? Many places in Henan have gone down to Chun Xue.

Thunderstorm and rain occurred in Zhengzhou, Henan Province, with white snow flying all over the sky and lightning and thunder. Thunderstorm and rain? Refers to the phenomenon of thunder accompanied by snowfall. The main reason is that the warm and humid airflow was strong before, and the cold air came down to produce strong convective weather, which triggered lightning activity.

Lightning and thunder thundered over Zhengzhou. However, it is snowing heavily, which makes people feel very surprised. There is usually lightning when it rains heavily. Why does it thunder and lightning in snowy days? In fact, this is related to the high temperature weather in eastern China. In the eastern part of China, especially in the North China Plain, there has been a rare rapid temperature rise in history. Central and southern Hebei Province is generally close to 30℃, and many places in Henan Province exceed 30℃. Temperatures in Shandong, Jiangsu, Anhui and Hubei are also very high, with high temperatures for three consecutive days. When cold air arrives, cold and warm air meet to form strong convection, so precipitation will occur. ?

? Due to the high temperature and long-term accumulation for several days, in the initial stage of cold and warm air convection confrontation, warm air should be given priority to, warm and humid air flow rises rapidly to form vertical convection, and when it is cold, it begins to condense to form precipitation, and more charges in the cloud begin to release, which is no different from the formation of thunderstorm weather in summer, so lightning and thunder will appear. At this time, precipitation is usually manifested as rain or hail, ice particles (so-called? Snow bug? ), but with the strengthening of cold air, cold air gradually gained the upper hand, lightning usually disappeared, and precipitation began to show snowflakes. If there is enough water vapor and more precipitation, there will be heavy snow and blizzard.

This phenomenon is also commonly known. Leixue town? Or? Thunderstorm and rain? But as the folk proverb says, it is usually considered unlucky to appear in the first month? Thunder in the first month, graves? ,? It thunders in the first month, and people don't cook? ,? In the first month, the thunder is loud and the earth is piled up? Wait, this is because the thunder in the first month means that the weather gets warmer in advance, but the warming in the first month is abnormal, which is not in line with the normal solar terms and climate change, because the warming in advance means that there may be late spring cold in the near future. The ancients thought that spring was the season when crops were planted and everything sprouted. If you suddenly encounter the cold in late spring, it will inevitably have an adverse impact on the growth of crops, vegetables, fruits and other crops. The most direct manifestation is that the yield in the field is reduced or even lost, and the poultry and livestock raised at home may freeze to death and get sick, so the food source of ordinary people becomes a problem, and people may starve to death if they don't eat, so there is such a proverb. ?

However, it is no longer the time to depend on the weather as before, and there are more and more means to deal with weather changes in agricultural production. When it is dry, it can be pumped to water the land, and when it is waterlogged, it can be discharged into the river. Although there is no good way to deal with the cold in late spring, the phenomenon of cold in late spring often appears in recent decades, which has not caused much negative impact on agricultural production. Moreover, it is no longer an era of completely relying on agriculture as in ancient times, so even if it happens, it will have a negative impact on people's lives.
