Which season has the most hail disasters?

Hail disasters are most common in spring and summer.

Most hail disasters in China will occur in spring and summer. Although there are many strong convection in summer, the frequency and intensity of hail disasters will be higher in spring.

The reason for this is that in spring, the convergence of cold and warm will be more frequent and the convection will be stronger. And the temperature will be higher in midsummer, and the height of 0 degrees Celsius will be very high. Maybe the ice crystal particles melted before they officially landed.

Moreover, a large part of China will hail from the afternoon of 13 to the afternoon of 19, which can be said to be the most common from the afternoon of 14 to the afternoon of 16.

In addition to Jiangxi, Hubei, Hunan, Guangdong and other regions, there will be a certain amount of hail in many places in China, especially in mountainous and hilly areas in the north. These terrains are not only complicated, but also the weather is changeable.

The omen before the hail:

If it is hail season, the weather will be cooler and the humidity will be higher in the morning, but strong convective air will be caused when the sun is bigger at noon. There may also be cumulonimbus clouds at this time, which will lead to hail. There is a saying that "dew is heavy in the morning and hail is fierce in the afternoon".

In addition, there will be a strong wind and great changes before the hail comes. If the south wind continues to blow, when the direction changes to north wind or northwest wind, when the wind increases, hail is likely to follow.
