Thanks Cactus, what you have said squares with what I've read, but it still leaves a small dilemma when related back to the JAA question which mentions just the snow.
Now is the static created by the cloud development (Cb, Ns), or by the snow itself.
If the latter then, the answer to the JAA question must be yes, but if the static is a product of the static charges within the cloud itself then the answer is no.
Of these two options which would you pick.
I have a feeling this question will soon be laid to rest. Thanks everyone for your input so far,
DA
