Where did the strong convective weather when the fire dragon fell into a tall building happen?
First of all, let's understand what strong convective weather is. Strong convective weather refers to sudden, destructive and disastrous weather, often accompanied by strong convective disasters such as thunderstorms, hail, tornadoes and local heavy rainfall. Strong convective weather has a small spatial scale and a short life cycle, but it can release powerful forces in a short time, which can cause houses to collapse, crops and trees to be damaged, telecommunications to be damaged, and serious casualties.
The formation of severe convective weather occurs in convective cloud system or single convective cloud block, in which small-scale weather system is mainly large-scale weather system, which is one of the key factors affecting its formation and development. For example, in the rainy season, cold and warm air flows meet in a large range and are affected by the underlying surface in a certain area, which is prone to heavy rain.
Strong convective weather in many places occurs in the rainy season. This year, the weather and climate are abnormal. Jiangnan District entered Mei in June 1, and on June 8, it was 7 days earlier than normal, and in July 1 1, it was 3 days later than normal. The plum blossom in Jianghuai area in June 10 was earlier than June 2 1 0, and on August 2, it was later than normal 18 days. This anomaly is closely related to the activity of the western Pacific subtropical high. In the middle and late July, the western Pacific subtropical high continued to be southward, with latitude 2 1? By 26? The characteristics of north-south swing are obvious, and the middle and lower reaches of the Yangtze River and the Meiyu area in Jianghuai are still obvious precipitation processes.
Finally, due to the sudden and destructive nature of strong convective weather, it often causes serious disasters. At present, there is no effective method of artificial weakening, and the strategy of combining prevention with elimination should be adopted. People pay more attention to the weather forecast, reduce outdoor activities, close doors and windows, quickly hide in shelters and stay away from scaffolding billboards and other structures.
