Lightning travels in a ragged course, but many segments of varying length are relatively straight. Each one of these segments points in a different direction, is of a different length, produces its own individual sound, and radiates its sound out in waves roughly parallel to its own orientation. Many individual “little thunders” of varying volumes and directions combine to make the total cracks, rumbles, and reverberations you hear in the one great, long peal of thunder.
The loud sound that follows a flash of lightning. It is due to the sudden expansion of air that has been heated by such electrical discharge, causing the air to move violently away from the lightning’s path and then back again behind it.—Job 28:26; 38:25.
The sound of thunder often being an advance indication of an approaching storm, “thunders” can designate divine warnings, as mentioned in the Bible as at Revelation 8:5; 10:3, 4.
