The heavy rain continues online. What do you know about severe convective weather?

The so-called strong convective weather actually refers to the occurrence of short-term heavy precipitation or short-term thunderstorms and strong winds. In addition, strong convective weather also includes tornadoes and hail, which is actually a disastrous weather. In fact, the occurrence time of severe convective weather is different in different parts of China. Generally speaking, Na Man appeared earlier, but in Guangdong, this kind of strong convective weather will appear all year round. If it is short-term heavy precipitation, it can be seen all year round, but it is usually more in spring, summer and autumn. If it is a thunderstorm and windy weather, it usually occurs in spring, summer and autumn, and it is rare in winter. If it is a tornado, it usually happens in the transitional season at the turn of spring and summer, and it also happens at the turn of summer and autumn. That is to say, it is the high incidence period of tornadoes from April to 10 every year. If it is a squall line, it usually occurs in the transition season of spring and summer. If there is a typhoon, it will also appear, mostly from March to September every year. If there is hail, it is mostly when the cold and warm air meet fiercely, and it is more frequent in February-May. However, it is also possible for land ice to appear in the remaining strong persistent thunderstorm weather, but this situation is generally rare. Strong convective weather generally occurs in local areas, but the destructive power is often very strong, and this kind of strong convective weather comes and goes quickly. But strong convective weather is usually predictable. Although it is really difficult to accurately predict a small area, you can find traces on the radar several hours in advance. It can be judged by the signs on the radar echo map. If it is light green, it means it will rain. If it is dark green, it means there will be heavy rain. If there is a red or even purple broadcast, it means that there will be strong convective weather such as thunderstorms and hail.
