Why is lightning so strong?

Why is lightning so strong?
There are three main reasons: first, the subtropical high. Since late September, the subtropical high has been entrenched over Chengdu, making Chengdu in the southwest warm and humid airflow at the edge of the subtropical high, resulting in high temperature, high humidity, weak wind and extremely unstable atmosphere; The second is the high-altitude cold air flow. From the night before last, there was a high-altitude cold air flow over Chengdu, which fell to low altitude and collided with the warm and humid air flow; Third, Typhoon Hagupit made landfall along the coast of Guangdong yesterday morning and moved northwest, bringing abundant water vapor and atmospheric energy to Chengdu. Under the combined action of these three factors, the lightning and thunder in Chengdu are constantly caused.
With such a strong thunderstorm, citizens have speculated whether it indicates another major earthquake?
This thunderstorm has nothing to do with the earthquake! Although the duration is long and the intensity history is rare, this is a natural discharge phenomenon in the atmosphere, which has nothing to do with the earthquake. There is no need for citizens to panic.
For this thunderstorm weather process, Chengdu Meteorological Observatory has released important weather news for many times and issued a yellow rainstorm warning, but why didn’t it issue a lightning warning for such a strong thunderstorm?
For this severe thunderstorm, lightning potential prediction has been released, including the approximate area, time and probability of lightning within 0-12 hours. However, this forecast is only aimed at the interior of the meteorological department and has not been released to the public. At present, Chengdu Meteorological Bureau has included the lightning forecast into the scope to be released. Recently, the lightning protection center will invite relevant departments to conduct technical appraisal on Lightning forecast. It is expected that citizens will be able to see lightning early warning forecast from relevant media in the thunderstorm season next year.
The possibility of reheating is very small
Since late September has entered autumn, why does the torrential rain still patronize our province? Fan Xiaohong: in the past, severe rainstorms also occurred in autumn in our province, which is not abnormal weather, but why is the energy of this thunderstorm so large? According to expert analysis, the main reason is the subtropical high. The energy gathered in the early stage suddenly broke out. In addition, there is sufficient water vapor, which is also related to the landing of typhoon.
After rainfall, all parts of the province have cooled to varying degrees. Will it get hot again in the future?
After the rainstorm, the basin has basically entered the autumn in the sense of meteorology. Except that it feels a little hot when the sun rises, it will feel very cool at other times, and the possibility of reheating is very small.
