Hail suddenly fell in Yantai, Shandong, and some of the hailstones were as big as eggs. How did the cold air form this time?
Hail suddenly fell in Yantai, Shandong. Some hailstones are as big as eggs. At that time, the cold air was mainly formed by the influence of climate. In autumn, the temperature difference between day and night is large and the temperature drops. Some small ice chips rise into the sky and encounter clouds, forming hailstones.
The main reason is that the temperature changes greatly. And we all know that it is autumn, so the arrival of autumn also symbolizes the emergence of cold temperatures, so some provinces and cities will have some cooling conditions. This time the hail also caused damage to many vehicles, and some trees were also hit by sudden hail. The reason for this cold air is that the current season gradually changes like winter.
The reason for this bad weather is due to the season. Although summer is hot, it is also the rainy season, especially in the south. In summer, the weather is very hot. The temperature on the ground continues to rise. Water vapor on the ground evaporates into the air and condenses into small water droplets. Eventually, under the influence of gravity, more than a small amount of the material accumulates, forming large droplets. It finally rained. When the cold air moves southward, a confrontation between cold and warm occurs, which will lead to heavy rain and other strong convective weather in some areas.
It is harvest season. Corn is being harvested in many areas, so the farmer's uncles are looking forward to good weather and enough time to dry their grain so that their grain can be bought at a good price. Now, suddenly a hailstorm fell. Those fields where the corn has been cracked are OK. The farmers who don't have time to harvest corn are miserable. I also hope that affected farmers can seize the opportunity and collect food from their fields quickly. I also hope those affected don't feel too sad.
Hail disaster is a serious meteorological disaster caused by strong convective weather systems. Although the occurrence range is small and the time is short, it has large momentum and intensity, and is often accompanied by sudden and disastrous weather such as strong winds, heavy precipitation, and sudden cold. Hail causes huge losses to my country's agriculture, forestry, transportation, construction and other industries as well as people's lives and property every year. When hail disaster occurs, car glass will break and even hit the car body.
