Does it hail in Qingdao in summer?

The main causes of hail formation are strong convective air and a lot of water vapor. Jiaodong Peninsula is surrounded by the sea on three sides. In summer, the surface (sea surface) heats up quickly, and a large amount of water vapor rises rapidly. When it is cold, it is easy to form hail.

Hail is solid precipitation with a diameter of more than 5 mm falling from strong cumulonimbus clouds ... The clouds of hail clouds are generally very thick, and the convection in the clouds is very strong ... The updraft in hail clouds is very strong, which sends the growing water droplets in the lower part of the clouds to the middle of the clouds to become supercooled water droplets.

The downward airflow in the cloud can bring the ice crystals and snowflakes in the upper layer to the middle, and the supercooled water droplets collide with the ice crystals or snowflakes and grow up to form graupel or naturally freeze into frozen droplets. From the time point of view, May and June are indeed the high incidence period of hail in Jiaodong.

For hail disaster, it is difficult to prevent it completely, and the loss can only be minimized. For individual fruit farmers, buying agricultural insurance may be a feasible way at present.

Hail in Qingdao first appeared in April, and at the latest appeared in 10. Among them, the hail concentration period in Qingdao is from May to June, and the hail time is relatively concentrated, mostly in the afternoon and evening when the temperature is high and the weather is sultry. Geographically, hail in Qingdao mainly occurs in the hilly areas of Jiaozhou and the western part of Huangdao, as well as the Daze Mountain Range between Pingdu and Laixi.

Although the hail didn't last for a few minutes, it did some damage to the fruit trees: the branches, fruits and leaves of the fruit trees were all hurt by the hail, and now it is the rainy season with high temperature. Various germs infect the wounds, which first turn brown or black, rot and then spread.
