Synopsis Invited Feedback Importance (/10, author rated :-) )
This solution popped out of chapter 3 of my thesis and was pointed out by my thesis examiner Norman Riley as being more important than I thought at the time. The nice thing about it is that it suggests strongly that a non externally driven vortex over a slipping surface (i.e. a waterspout) can only have a two-cell structure if there is downflow on the axis. This is exactly what is observed in nature and it is very marked as the inner core is clear. Waterspouts are really beautiful without the extraordinary destructiveness of tornadoes. Needless to say as I write this in 2003, thirty years after I did this work, I still haven't seen either. :-(None yet9
