What is heavy rain with thunder and lightning?
thunderstorm, a violent short-lived weather disturbance that is almost always associated with lightning, thunder, dense clouds, heavy rain or hail, and strong gusty winds.
What is the actual sound of thunder?
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.
How does a storm sound like?
With nearby lightning strikes the thunder will sound like a loud bang, crack or snap and its duration will be very short. At large distances from the center, the shock wave (thunder) can be many miles across. To the listener, the combination of shock waves gives thunder the continuous rumble we hear.
What does a constant rumble of thunder mean?
The answer to the constant rumbling you hear in storms is a simple one: it’s thunder. Really strong storms that contain hail will certainly have lightning and increasing lightning rates can be a sign of a strengthening storm, which means a strengthening updraft, which means hail becomes more likely.
Can you have thunder without lightning?
No, it is not possible to have thunder without lightning. Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating. However, it is possible that you might see lightning and not hear the thunder because it was too far away. Thunder is caused by lightning.
Does lightning have a sound?
This rapid expansion and contraction creates the sound wave that we hear as thunder. Although a lightning discharge usually strikes just one spot on the ground, it travels many miles through the air. The loud boom that you sometimes hear is created by the main lightning channel as it reaches the ground.
What is the longest thunder Rumble?
The United Nation’s World Meteorological Organisation (WMO) has just announced that the longest lightning strike on record was a 2007 bolt in Oklahoma that stretched 321 km (200 miles) – almost reaching from one side of the state to the other.
