Jupiter and Saturn emit nearly twice the thermal energy they receive from the Sun. Although
insolation decreases toward the poles, the large-scale outward heat flux is nearly uniform,
with smaller-scale latitudinal undulations that correlate with the zonal jet streams. Here we
present numerical models of rapidly rotating, turbulent 3-D convection in geometrically thin,
uniformly forced layers of Boussinesq fluid that approximate the deep convection zones of
