In the evening, some areas in Shapingba District and Yubei District of Chongqing began to hail. Hail, as big as a marble, falls intensively and urgently, and thumps on the ground.

Hail usually occurs when cold and warm air meet violently from February to May in Gregorian calendar, and it may also land in a strong and persistent thunderstorm in midsummer. Every year, all parts of China are hit by different degrees of hail. Especially in the mountainous and hilly areas in the north, the eastern part of the Qinghai-Tibet Plateau and the Yunnan-Guizhou area, the terrain is complex, the weather is changeable and there are many hail, which is very harmful to agriculture.

Hail prevention and control

China is one of the countries with earlier artificial hail suppression in the world. Due to the serious hail disaster in China, the hail suppression work has received the attention and support of the government. By 20 13, many provinces have established long-term experimental fields, conducted rigorous experiments and achieved many valuable scientific research results. Artificial hail suppression is carried out to make it develop in the direction people expect and achieve the purpose of disaster reduction.

On the ground, catalysts such as silver iodide, lead iodide and dry ice are sent to the free atmosphere before the formation of cumulonimbus clouds, so that these substances play the role of hail embryos in hail clouds, making hail embryos larger and hail smaller.

In areas prone to hail, planting grass and trees can increase forest area, improve landform environment and destroy hail cloud conditions, thus reducing hail disasters. A variety of crops with strong hail resistance and resilience will be harvested in time. In the hail season in the hail-hit areas, farmers carry hail prevention tools, such as bamboo baskets and wicker baskets, to reduce personal casualties.
