Why is there so much strong convective weather this summer?

Severe convective weather refers to the disastrous weather such as short-term heavy precipitation, thunderstorm and gale, tornado, hail and squall in convective cloud system or single convective cloud block, which belongs to small and medium-sized weather system in meteorology.

Strong convective weather occurs in convective cloud system or single convective cloud block, which belongs to small and medium-scale weather system in meteorology. The horizontal scale of this weather is generally within 200 kilometers, and some are only a few kilometers. This kind of weather is extremely destructive. It is a weather with short duration and strong destructive power in meteorological disasters. Worldwide, it is listed as the fourth most disastrous weather after tropical cyclones, earthquakes and floods.

Convective weather is easy to form and develop in some specific areas, such as on both sides of mountains, at the border between land and sea, around lakes and swamps. Therefore, the physical process of the formation of various severe convective weather is not exactly the same, which is closely related to the influence of dynamic and thermal effects of the underlying surface.
