What are the signs of thunder and lightning in spring?

We often encounter the phenomenon of thunder in spring, and its symptoms are:

1. The thunder of spring indicates that winter has passed and spring is coming. Spring has come, and many hibernating animals are awake. When they wake up, they are all around the "fright". "Sting" is one of the 24 solar terms. "Sting" means hiding. "February Festival, everything is shocked, shocked by thunder, hence the name". 2. "Stunned" means that the wintering animals are awakened by the thunder of spring and come out for activities, which is also a warning to the coming of spring. Every spring, especially after dormancy, the obviously enhanced warm and humid air and cold air violently confront each other, resulting in a strong vertical convection movement of the air. Spring has come. With the enhancement of warm and humid air and abundant water vapor, the towering thunderstorm cloud system develops, so spring thunder occurs every year.

Every spring, the obviously enhanced warm and humid air confronts the cold air fiercely, resulting in strong vertical convection movement of the air. When the moist warm air rises to a certain height, it will form a high cumulonimbus cloud, and the strong electric field in the cloud will make the positive and negative charges collide and discharge, thus causing sudden lightning. Typhoon is formed because the air at the bottom will rise when heated.

In areas with high temperatures, when some disturbances in the atmosphere happen, a large amount of air will rise, which will reduce the air pressure on the ground. At this time, the air outside the rising area continues to flow into the rising area. Because of the rotation of the earth, the flowing air will turn like a wheel, which is also one of the reasons for the typhoon. After the rising air expands and cools, the water vapor in it cools and condenses into water droplets, releasing heat, which in turn promotes the rise of low-level air, reduces the ground pressure and makes the air rotate more violently, thus forming a typhoon.
