We have discovered, however, that any difference between model simulations produces a rapid propagation of very small changes throughout
all prognostic model variables at a rate many times the speed of sound.

In more sophisticated
models some of what were boundary conditions in simpler
models have now become
prognostic variables.
Secondly, deterministically formulated climate
models are incapable of predicting the uncertainty in their predictions; and yet this is a crucially important
prognostic variable for societal applications.
But complex
models of that sort can easily produce more than 100
prognostic and diagnostic climate
variable outputs, at each of around a million grid points, for each
model day, and almost all of these are averages which need to be downscaled to get useful information at point scale.
