The one that really interested was the bit about lightening sprites. Absolutely fascinating, something that we never see because it happens above the storm, which normally last between 10 and 100 milliseconds! They are triggered by the discharges of positive lightning between the thundercloud and the ground.
But there is a lot more going on up there...
The sprites remind me of jellyfish, i have to admit, when i saw them happen on the program i got goose-bumps[/geek]
I'm off to watch Animals in The Womb. I seem to be on an education binge.
Go watch the Invisible World.
