The animation below shows the cloud field (white volume shading) and precipitation field (surface colors) for a six-hour simulation by GFDL's FV3 atmospheric model, run in a doubly-periodic, radiative-convective equilibrium configuration on a 25km x 25km domain with horizontal resolution dx=250 m and a fixed SST of 300 K. The cloud field is comprised of the 2e-5 contours of the non-precipitating condensate field.
