Whirlpool Whirlwind

Well as you might be able to guess this is not a body of rotating water produced by opposing currents which has been whipped up by a ferocious storm - it's actually part of a station car park roundabout. It was an emergency blip when I picked my brother up.
Bit of an admission here - I have used this as a blip subject before. That time I called it a Supernova! :-)
