The difference between spring thunder and summer thunder

Because of the dry climate in spring, there are few thunderstorms. Even if there are, it is "spring thunder bursts", which sounds softer, like a little girl telling you a story about spring. On the other hand, Xia Lei is noisy and huge, but it comes and goes in a hurry.

Meteorologists explained that the thunder in spring is different from the thunder in summer, and the biggest difference lies in the time when the thunder appears. In spring, people are awakened by the rumble of thunder from midnight to morning in their sleep, which is called "spring thunder dream"; In summer, thunder is rarely heard when sleeping, because most summer thunderstorms occur in the afternoon to evening.

Spring thunder mostly occurs in the area where cold and warm air masses meet. When two cold and warm air masses meet, warm and humid air crawls on the back of cold air. During the day, the clouds are very hot by the sun, the temperature is easy to rise, the head of the atmosphere is lighter, the stability is increased, and the possibility of forming thunderstorms is reduced. At night, the cloud top radiates heat into space, and the temperature in the upper part of the cloud drops, especially from midnight to morning, the temperature drops to the lowest level in a day, and the head of the atmosphere becomes heavier.
