How did lightning and thunder come from?

Lightning is a plasma conduction state formed by extranuclear electrons of space gas excited by electric field, accompanied by optical radiation and thermal effect.

Due to the action of light and thermal radiation, the temperature of the surrounding air rises sharply, leading to thermal expansion, which in turn pushes the air to form a shock wave, that is, the sound of thunderstorm we hear. The greater the concentration of water molecules in the air, the more impurities there are, the greater the possibility of breakdown ionization by high-voltage electric field, and the higher the probability and intensity of lightning strike.

Lightning and thunder are common weather phenomena in summer, while it usually snows in winter. These are two completely different weather phenomena. However, as long as the weather in a certain place has the conditions of snow and thunder at the same time, these two completely different weather phenomena can appear at the same time.
