how do you
work out how far away a storm is, using the lightning/ thunder principle?

Go out side and hold out a long metal rod
When you are struck you know its close

Roughly a second a mile
but it is very approximate.

2 and half miles
eep!

I thought it was a kilometer a second.

sound travels
AT 300m/s in air

Depends on the viscosity
of the rain in the air tho dunnit ?

Yes, it does*
*No, it doesn't. At all.

roughly a mile every five seconds
is less approximate

Then that means...
half a mile

one of the safest places to be
is in a car. Off you go.

approximate to the point of complete inaccuracy
sound travels about a mile every five seconds

edit: which makes flapjack a mach 3 fighter jet, and me a badly-made paper dart

I think it's something to do with the storm being very high up
So the sound has to go down the long side of a triangle. Or something. I saw a picture in a book, once.

I stand,
very much corrected.

So much for my engineering degree!

Speed of sound is about 5 seconds to the mile.
Number of seconds from flash to bang / 5 = number of miles to epicentre*.

sharp teeth
I think. bitey.

I think the meteorologists' term is
a 'bastard'. As in "Look! There's the bastard!"
