So, what is strong convective weather?

Strong convective weather refers to convective gale (17.2 m/s), hail and short-term heavy precipitation accompanied by thunderstorms.

Strong convective weather occurs in small and medium-scale weather systems, and the spatial scale is small. Generally, the horizontal range is about ten kilometers to two or three hundred kilometers, and some horizontal ranges are only tens of meters to ten kilometers. Its life history is short and obviously sudden, ranging from an hour to more than ten hours, from a few minutes to an hour.

In 20 13, there were three severe convective weather processes in southern China, such as thunderstorm, hail or tornado, which caused serious losses to people's lives and property in some areas. /kloc-from 0/9 to 20, the largest range of strong convective weather occurred in the southern region so far.
