Thunder

v. make a roaring sound

n. booming sound in the air created during stormy weather

Thunder is the sound made by lightning. Depending on the nature of the lightning and distance of the hearer, it can range from a sharp, loud crack to a long, low rumble. It is produced by a sonic shock wave caused by the rapid expansion of the air surrounding and within a bolt of lightning.
