A Cumulus Parameterization Study With Special Attention to the Arakawa-Schubert Scheme (semi-Prognostic, Meso-Scale Simulation)
Arakawa and Schubert (1974) developed a cumulus parameterization scheme in a framework that conceptually divides the mutual interaction of the cumulus convection and large-scale disturbance into the categories of large-scale budget requirements and the quasi-equilibrium assumption of cloud work …

CWRF summer precipitation prediction over the United States land and coastal oceans: effects of ensemble cumulus parameterization closures
… still exhibit biases and are highly sensitive to cumulus parameterization (CUP) especially during the summer. Most current models also tend to predict rainfall too early in the daytime and too frequently at the light intensity over both land and oceans. These problems have been identified with …

Application of the Weather Research and Forecasting (WRF) Model to Simulate a Squall Line: Implications of Choosing Parameterization Scheme Combinations and Model Initialization Data Sets
… study was to examine the performance of several parameterization scheme combinations in the Weather Research and Forecasting Model version three (WRF) as they related to this event. These examinations included cloud microphysics (WRF Single-Moment 3-class, 6-class, and Goddard), cumulus …

Evaluating CFSv2 Subseasonal Forecast Skill with an Emphasis on Tropical Convection
… be tied to mean state biases originating from cumulus parameterization, affect atmospheric teleconnections and could thus degrade extended global forecast skill.

Convective Transport of Tropical Marine Boundary Layer Species into the Upper Troposphere and Relation to Species Lifetime: In Situ Measurements and Global Model Simulation
… from measured trace gasses indicating that their cumulus parameterization schemes are working reasonably well. Determining efficiency of convective transport for tracers of varying lifetimes is crucial for understanding not only the dynamics of these deep convective systems, but also the chemical …

Toward better subseasonal-to-seasonal prediction: physics-oriented model evaluation and predictability of tropical cyclones
… in the NOGAPS, suggesting a model deficiency in cumulus parameterization. The diabatic heating biases are associated with weaker trade winds, weaker Hadley and Walker circulations over the Pacific, and weaker cross-equatorial flow over the Indian Ocean. The TC prediction was evaluated in the …
