What are the natural disasters in Hainan?

There are many kinds of climatic disasters in Hainan, and the main disasters are: tropical cyclone, rainstorm, drought, cold dew wind, Qingming wind, low temperature rain, hail, tornado and so on.

1. Tornado: It is the strongest vortex phenomenon in the atmosphere. It is a strong wind vortex with small range and strong wind force extending from the bottom of thunderstorm cloud to the ground or water surface. It mostly occurs in thunderstorm weather in summer, especially in the afternoon to evening, which has little influence but great destructive power;

2. Tropical cyclone: it is a strong weather system that occurs in the tropical ocean. Like a vortex moving forward in a flowing river, it rotates rapidly around its center and moves forward with the surrounding atmosphere;

3. Qingming wind: it is one of the eight winds in a year, which can also be called southeast wind. The meteorological Qingming wind refers to the cold damage that Hainan Province may encounter when heading and flowering. Because of the early season in Hainan Province, Tomb-Sweeping Day gas has entered the booting and heading stages. At this time, if it is affected by cold air, it will lead to the increase of false grain rate and empty grain rate and reduce the yield. Therefore, Qingming wind is a unique cold weather in Hainan, which is seriously harmful to early rice production.
