When i meant supercell I meant the meso-cyclone variation of it
The definition of a supercell is a tstorm with a persistent mesocyclone.
that the whole thundercloud spins which is mainly to do with updraft not wind shear, correct?
Kind of correct. tstorms rotate a lot easier when the instability is very high, but of course there still needs to be some shear.

The Oakura F1 last year was accompanied by a thunderstorm whereas the F1 in Cambridge wasn't. The F2 at Greymouth back in March 05 didn't come with thunder.
05 Greymouth Tornado was associated with Thunderstorm activity. http://www.metservice.co.nz/default/ind ... 005autumn1 Thunder may not have been heard in Greymouth ?
