Actually, I don't think so. Because of the chaotic nature of the
equations, slight differences in the starting conditions lead to vastly
different solutions given enough time.

But the thing is that you *always* have error in the initial
conditions, and that's why AFAIK the weather guys run multiple
simulations with somewhat varied starting points, and the forecast is
then compounded from the different results.

In any case, the models are pretty heavy to run and I don't think it's
really a market segment for Octave.

But yes, an arbitrary precision linear algebra addition to Octave would
be very useful.
