Most of the evening thunderstorms in summer are caused by "heat thunder. The sun's strong rays heat the earth's surface, causing upward air currents that destabilize the atmosphere and create cumulonimbus clouds (ingress clouds). Heat thunder is generated by these cumulonimbus clouds.
This type of lightning often occurs during the change of seasons. When two different air masses, one warm and one cold, come into contact with each other, they do not immediately mix, but instead form a cold front and a warm front. When these two different types of air masses come into contact with each other, they do not immediately mix and form a cold front and a warm front. Field thunderstorms occur when thunderclouds form near these two fronts.
Vortex lightning occurs near the center of a low pressure system or typhoon when air currents blowing in from the surrounding area cause a stronger than normal updraft. When the temperature is high, vortex lightning remains strong for a long time and affects a wide area because of its fast moving speed.
Volcanic lightning is caused by frictional electricity generated by rising air currents from violent volcanic explosions, which is then discharged.

People tend to think that lightning is a meteorological phenomenon that occurs mostly in summer, but in fact lightning occurs in winter as well. Outside of Japan's Sea of Japan coast, lightning is limited to the Atlantic coast of Norway, and is a very rare weather phenomenon worldwide.
