How bad is the snowstorm weather in Zhengzhou, where many places in Henan have fallen to Chun Xue?

It rained in Chun Xue in Henan, and it snowed in Zhengzhou. How bad was the local snowstorm?

there is a phenomenon of thunder and snow in Zhengzhou, Henan province, where bai snow flies all over the sky, lightning and thunder. Thunder and snow? It refers to the phenomenon of thunder accompanied by snowfall. The main reason is that the warm and humid air was stronger before, and when the cold air came down, it produced strong convective weather, which triggered lightning activities.

lightning flashes and thunder rumbles over the downtown area of Zhengzhou. However, it is snowing heavily in the sky, which makes people feel surprised. It usually happens when it rains heavily. Why does it thunder and lightning in snowy days? In fact, this is related to the high temperature weather in the eastern part of China. The eastern part of China, especially the North China Plain, has experienced a rare rapid temperature rise in history. The central and southern parts of Hebei Province are generally close to 3℃, while many places in Henan Province have exceeded 3℃. The temperatures in Shandong, Jiangsu, Anhui and Hubei are also high, and the temperatures are very high for three days in a row. When cold air arrives, cold and warm air meet to form a strong convection, so precipitation will occur. ?

? Due to several days of high temperature and long-term accumulation, in the initial stage of cold and warm air convection confrontation, warm air should prevail, 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 clouds begin to release, which is no different from the formation of thunderstorm weather in summer, so lightning and thunder will occur. At this time, precipitation is usually manifested as rain or hail, ice particles (so-called? Snow bugs? ), but with the strengthening of cold air, the cold air gradually gained the upper hand, and the lightning phenomenon usually disappeared, and the precipitation began to show as snowflakes. If the water vapor is sufficient and the precipitation is relatively heavy, there will be a blizzard phenomenon of heavy snow.

this phenomenon is also commonly called? Lei Zhenxue? Or? Thunder and snow? But it is often considered unlucky to appear in the first month, as the folk proverb says? Thunder in the first month, graves piled up? ，? Thunder in the first month, people don't cook? ，? In the first month, thunder and earth piled up? Wait, this is because the thunder in the first month means that the weather is getting warmer in advance, but the warming in the first month is abnormal, which is not in line with the normal solar season and climate change, because the warming in advance means that there may be late spring cold in the near future, and the ancients thought that spring is the season for planting crops and sprouting everything. If it suddenly encounters late spring cold, it will inevitably have an adverse impact on the growth of crops, vegetables, fruits and other crops. The most direct manifestation is that the output of the field is reduced or even not harvested, and poultry and livestock raised at home may also get sick from freezing, so that the food source of ordinary people becomes a problem, and people may starve to death if they don't eat, so there will be 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 the weather change in agricultural production. When it is dry, it can be pumped to water the land, and when it is waterlogged, it can be drained to the river. Although there is no good way to deal with the cold in late spring, the phenomenon of cold in late spring has often appeared in recent decades, which has not caused much negative impact on agricultural production. Moreover, it is no longer the time to rely entirely on agriculture as in ancient times, so even if it occurs.
