Qianxi county weather forecast

On the evening of May 9, 20021year, strong convective clouds appeared in southern China, and thunderstorms and hail occurred in most parts of Fujian Province. Coincidentally, squall lines also appeared in Guizhou Province, located in Yunnan-Guizhou Plateau of China. On the evening of May 9, affected by the squall line, many places in Guizhou suffered from strong wind and rain. According to the monitoring data, a squall line in Guizhou Province caused a gale at qianxi county National Station 12 with a wind speed of 33.4m/s. Strong convective weather is not uncommon in Guizhou, but it was really fierce on the evening of May 9. Thunderstorms are frequent, including Guiyang, the capital of Guizhou Province, which was hit by short-term heavy rain. Photos of netizens show that there is even hail in Guiyang at night, which is bigger than eggs. This kind of hail and strong wind has certain destructive power. Some netizens said that the window sound is particularly loud, which may bring more serious harm to local agricultural and forestry production in Guizhou.

Short-term convective weather is normal summer weather. As summer approaches, I begin to see more and more convective weather, such as showers and thunderstorms. From spring to summer, it is easy to hail. But if we infer from common sense that it can be formed not only in cold winter, but also in summer, it will be really chaotic. Due to China's wealth and vast territory, the climate varies from place to place, and some areas are always affected by hail.

A large amount of water vapor rises rapidly to the sky after being irradiated by strong sunlight in hot summer, and falls into ice crystals after encountering cold air. In the process of falling, the water droplets in the air adhere to each other and become blood beads, and the blood falls again, returning the rising high fever to the sky. The circle is getting bigger and bigger like a snowball in the cloud, and the rolling weight is getting heavier and heavier. When it reaches a certain weight, it will fall directly to the ground. This is the so-called hail, small hail such as soybean eggs, and more exaggerated chopsticks, irregular hail, and the shape of the ball.

Hail is a short-term strong convective weather. According to yesterday's weather forecast, there will be short-term strong convective weather such as heavy rain, heavy rain and short-term strong wind in the south and southeast of our province. The main reason is the strong convection movement. Under the interaction of cold and warm air, the precipitation conditions were met, and some precipitation appeared in the form of hail. The internal structure of infrared ray is uneven, but there is a shell in the middle, which is mainly composed of water droplets. A small amount of oil droplets freeze to form a transparent ice shell. Ice will be mixed with fragments of different sizes, and some hail can be as high as 10 or even as high as 30 layers. In fact, in the hail, you will find many large hailstones, some as big as a washbasin, or even more exaggerated, like a car.
