With a uniform mix of cloud types, the three cloud types that produce most of the total cloud effect on the TOA shortwave fluxes are deep convective, nimbostratus, and cirrostratus; and for the surface shortwave effect, the three most important cloud types are the three thickest cloud types, namely deep convective, nimbostratus, and stratus. With a realistic mix of cloud types, the cloud types that produce most of the total cloud effect on the shortwave fluxes (both TOA and surface) are the three cloud types with moderate optical thicknesses, stratocumulus, altostratus and cirrostratus.
With a uniform mix of cloud types, the three cloud types that produce most of the total cloud effect on the TOA longwave fluxes are the three high-level cloud types, deep convective, cirrostratus, and cirrus; and for the surface longwave effect, the three most important cloud types are stratocumulus, stratus, and altostratus. With a realistic mix of cloud types, the three cloud types that produce most of the total cloud effect on the TOA longwave fluxes are still the three high-level cloud types, but in a different order, cirrus, cirrostratus, and deep convective; but for the surface longwave effect, the three most important cloud types are stratocumulus, cumulus, and altostratus.
With a uniform mix of cloud types, the three cloud types that produce most of the total cloud effect on the in-atmosphere shortwave fluxes are cirrostratus, deep convective, and stratus, with the former two cloud types decreasing the shortwave heating and the last one increasing the shortwave heating. With a realistic mix of cloud types, the cloud types that produce most of the total cloud effect on the in-atmosphere shortwave fluxes are cirrostratus, cirrus, and stratocumulus, with the former two cloud types decreasing the shortwave heating and the last one increasing the shortwave heating.
