One might argue that the fluid dynamics of the atmosphere are arriving at exact solutions to the Navier-Stokes equations in real time, and that this is indistinguishable from a computer doing the same thing. Thus, the atmosphere is accomplishing a feat of computation well beyond our current technological and mathematical sophistication.
FWIW, I don’t agree with this definition of “computation.” I think “computation” requires the ability to artificially recapitulate a system under arbitrary boundary conditions, which is clearly not the case with the atmosphere.
