A dynamically based parameterization of organized moist convection in the form of multiscale coherent structures and slantwise layer overturning principles provides upscale heat and counter-gradient momentum transports distinct from diffusive down-gradient mixing by unorganized cumulus. Implementation of a minimalist version of this new parameterization in a state-of-the-art global climate model (GCM) improves the Madden-Julian Oscillation and convectively coupled waves and generates large-scale patterns of tropical precipitation consistent with Tropical Rainfall Measuring Mission satellite measurements. A question on the need to parameterize mesoscale convective organization to mitigate mean state biases is addressed.
