how thunders are formed?

Answer 1

Thunder is the pressure wave of the lightning event. When there is lightning there is thunder, and when there is thunder there is lightning.

Thunder contains a roughly cylindrical initial pressure shock wave at the lightning channel in excess of 10 atmospheres. The shock wave decays to a sound wave rapidly, within meters. When thunder is heard about 100 m distant it consists of one large bang,. When heard about 1 km from the lightning, generally thunder will rumble with several loud claps sometimes being reported.

Readers are directed for further reading to three excellent studies of thunder: Rakov & Uman, Lightning Physics and Effects (2003), pp. 373-393; Uman, The Lightning Discharge (1987), pp. 281-312; and Hill in Golde’s Lightning (1977) pp.385-406.

Answer 2

The aftermath a a lightning strike. When protons from the sky meet neutrons from the ground during a storm and a lightning bolt forms, the thunder that you hear is actually the lightning itself, just from a farther distance. Use this method: For every second and 1/2 after you see a lightning bolt then hear thunder is approx how far the lightning was from your location. Example: 1 thousand 1, one thousand 2, one thousand 3....etc.....

Answer 3

Lightning is positively charged ions; when lightning is produced, it leaves a huge vacuum. Thunder is simply air rushing back in to the vacuum.
