What are the phenomena of strong convective weather?

1, strong convection is sudden thunderstorm, strong wind, hail, tornado and other weather with small scope, strong momentum but unpredictable. Generally speaking, the more intense the cold-warm collision, the higher the early temperature and the stronger the strong convection.

2. Moreover, 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, about one hour to more than ten hours, and the shorter one is only a few minutes to an hour.

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

4. Strong convective weather occurs in different places at different times. The south comes earlier than the north, and strong convective weather in Guangdong may occur all year round.

5. Thunderstorms and strong winds mostly occur in spring, summer and autumn, and are rare in winter. Short-term heavy precipitation can be seen all year round, mostly in spring, summer and autumn.

6. Tornadoes usually occur at the turn of spring and summer or at the turn of summer and autumn (April ~ 10), and the former is mostly. Squall lines often occur in the warm area before the cold front in the spring and summer transition season, and they often appear in the typhoon front, mostly from March to September. Hail mostly occurs in February-May when cold and warm air meet fiercely, and it can also land in the intense and persistent thunderstorm in midsummer.
