Put simply - chaos in action!

If I might be permitted a small hobby-horse aside here, I do wish this
word chaos had never become associated with atmospheric modelling. To
my way of thinking, this behaviour is not chaotic at all, it's
sensitive, or super/hyper-sensitive if you will (to the starting
conditions). Chaotic - to me - implies irrational or unknowable, which
is not what's happening here. Once you can define the starting
conditions with sufficient accuracy then the models can indeed run
with a rational outcome and so aren't chaotic.
