    I never heard of a gravity wave until I saw this. Definitely worth a look!

    No worries, I just thought people might like to see it.

    PS glad I wasn't anywhere near that fire!

    A common occurance in the forest fires.
    Seen a prog before on nat geo when two massive rows of hay bails in the states caught fire and generated one of these fire tornados.
    Unlike normal twisters when air masses interact,these are fuelled by oxygen.The bigger it became the faster the intake of air and was just as powerful as a twister.Fire brigades could do nothing about it as fear of them being sucked in they let it burn itself out, and soaked the surrounding countryside instead as its stationary where its fuel source is(fire) while twisters as we know them travel about.

    Wow that was impressive. It was hardly gravity though, surely?

    That is actually a common occurance all over the world. The almost unifrom dive in the cloud base is most associated with violent thunderstorms. These can also be called 'super cells'. We never see these in Ireland but they are frequent in the deep south in the US. Literally they are like waves as the atmoshere is very disorted between cold and warm air. Incidentally the video you have linked is condusive to tornado development.
