What is the sudden hail of soybeans in many places in Henan?
The biggest impact of hail disaster is the harm to agriculture, especially fragile crops such as vegetables and flowers. In addition, there are many cases of hail wounding in China. In some extreme weather, big fist hail falls from the sky, posing a serious threat to people's life safety.
? After the surface water evaporates and rises into the air, the water vapor gathers together through the condensation nucleus, forming raindrops around the condensation nucleus. With the gradual increase of condensed water vapor, the clouds can't hold raindrops, and raindrops fall to form rainfall. If raindrops encounter air with a sharp drop in temperature or extremely cold when falling, they will hug each other tightly and form a relatively large ice mass, which is called hail. Extended data: At present, with the help of advanced weather warning system, the occurrence of hail weather can be predicted, and disaster prevention and mitigation work can be done in advance.
? For example, we can transport some catalysts, such as dry ice, to the clouds by means of vehicles such as rockets and airplanes, so that the clouds will start to rain before the formation of heavy hail, thus reducing the harm of hail. For agriculture, changing the surface environment and increasing the forest coverage rate are also effective ways to reduce hail disasters. For people, the most effective way to reduce hail disaster is to reduce travel and stay indoors as much as possible in hail weather.
