Mani Gandham, adtech/enterprise/software/startups. Views. Thunder is the sound caused by lightning. When a lightning bolt strikes, the air immediately around it is superheated by the pressure and temperature of the electricity. This heated air rapidly expands and creates a sonic shock wave similar to a bomb explosion or when a jet breaks the sound barrier.
Thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. From the clouds to a nearby tree or roof, a lightning bolt takes only a few thousandths of a second to split through the air. The loud thunder that follows the lightning bolt is commonly said to come from the bolt itself. However, the grumbles and growls we hear in thunderstorms actually come from the rapid expansion of the air surrounding the lightning bolt. As lightning connects to the ground from the clouds, a second stroke of lightning will return from the ground to the clouds, following the same channel as the first strike. The heat from the electricity of this return stroke raises the temperature of the surrounding air to around 27,000 CÂ° (48,632 FÂ°).
