In which season and when does thunderstorm weather mainly occur?

1. Thunderstorms mostly occur in the season when the annual precipitation is relatively concentrated. Due to the different climate between north and south, thunderstorm weather generally appears in April-September in the south and June-September in the north.

2. Thunderstorm is a bad weather phenomenon caused by extremely unstable air. It is often accompanied by strong winds, heavy rains, lightning, lightning strikes, and even hail or tornadoes, so it can often cause disasters.

3. The birth of thunderstorm: The life of a single thunderstorm cloud (cumulonimbus cloud) is very short, usually only one or two hours, and the period can be divided into three stages: development stage, maturity stage and dissipation stage. In the first stage, an updraft is formed, sending warm and humid air into the air. When the rising air gets cold, the water vapor in it begins to condense and turn into clouds. As the airflow continues to rise, the clouds will accumulate higher and higher and go straight to the colder altitude. The water droplets in the clouds are getting bigger and heavier. Some are frozen into snow or hail, and some raindrops are getting bigger and bigger until they can no longer support the updraft. Downward flow, which comes when it rains or before it rains, will cause cool gusts, which means a thunderstorm is coming.
