What are the signs of thunder, rain and snow in winter?

It's not easy to thunder in summer and snow in winter. Therefore, "thunderstorm and rain" is an abnormal climate phenomenon, and the ancients thought that thunderstorm and rain were ominous. As the saying goes, "When it thunders and snows, people eat iron" and "When it thunders in the first month, there is a drought of 180", which means that it thunders and snows, which indicates a bad year. Of course, this is unfounded. When the hot and humid air on the ground is heated and meets the cold air at high altitude, the water in the air will condense into small water droplets and ice crystals. These small water droplets will keep rolling up and down, the hot air below will push the small fog droplets up, and the cold air above will push the small water droplets or ice crystals down, forming charge transfer between rising and sinking.

The positively charged particles gather directly above the clouds, and the negatively charged particles gather directly below the clouds. When the power of the two is increasing, they collide with each other to release instantaneous current. At the moment when the current is released, it will produce high temperature, which will cause the surrounding air to expand violently and produce explosive vibration. This is thunder.
