Appeared in Zhengzhou, Henan? Thunderstorm and rain? Phenomenon, is this phenomenon common?

On the evening of February 24, Zhengzhou, Henan Province appeared? Thunderstorm and rain? As a special phenomenon, goose feather snow is accompanied by rolling thunder. Zhengzhou Meteorological Observatory also issued a yellow warning signal for blizzard lightning, and Zhengzhou also launched a first-level snow removal plan. The Henan Meteorological Observatory also issued a yellow warning of road icing at 05: 00 on the 25th, and predicted that the road surface temperature in six areas, north of the Yellow River and Zhengzhou, would be lower than 0℃ in the next 12 hours.

It is not unusual to thunder in rainy days, but it is rare in snowy days. This phenomenon is called. Thunderstorm and rain? . Is this a new kind of extreme weather? Let's see what this unusual thunderstorm is.

According to Liu Huosheng, director of Wuhan Meteorological Observatory, what is the name of this weather phenomenon accompanied by thunder during snowfall? Thunderstorm and rain? It is the product of strong convection of cold and warm air. ? Like other seasons, lightning in winter is also a discharge phenomenon in the atmosphere, which is the product of fierce struggle between cold and warm air and collision between upper and lower air masses. When the temperature in one area is warmer in winter and meets the strong cold air in another area, the sharp temperature difference will make the warm and humid air flow rise rapidly, aggravate the air flow, produce strong convective weather, and then form? Thunderstorm and rain? . ?

Thunderstorm, rain and snow are rare, because the low-level and ground temperatures are very low in winter, and there is not much chance that convection will be strong enough to produce lightning. In addition, Ban Haoran, director of science, technology, meteorology and technology of Ji Xiang, also said that traffic accidents and lightning accidents are prone to occur in thunderstorm, rain and snow.

Therefore, try to avoid going out in rainy and snowy weather. If you have to go out, you'd better wear rubber shoes and raincoats, and stay away from power equipment and metal pipes. At the same time, you should also pay attention to the influence of snow and road icing on traffic. The electric power, communication and related departments should do a good job in the prevention of wire icing in alpine mountain areas. When the load of electricity and gas increases in low temperature weather, it is necessary to strengthen the safety protection measures of electricity and gas.
