Well, I've got it coded in now with appropriate messages for weather
changing, etc. Going to speed up weather on a development version and see
what it produces. I'm confident that it can be made to simulate
interesting weather systems, and that it provides scope for things like
weather control by mortals (a raise humidity or raise wind spell, for
instance, etc) that is very easily implemented.

Right. I'm not really sure how important detailed weather is. I wanted a
system that produces semi-emergent weather patterns largely becuase I
think it's cool. I am excited (and the mortals will be too) about the
possibility of weather-inspired natural disasters though, such as tornados
and the flooding of rivers. (though there's no reason why you couldn't
just fake a system, as Mik talks about above, and stick in random chances
for tornados, and floods as a result of extended rainfall).

I guess the major advantage I see is that the sort of system I'm trying to
do is easily amenable to interesting weather control abilities by players
and Gods. I also think it will produce more interesting weather, in the
same way that the game of Life produces spontaneously interesting
