A new approach to the cumulus parameterization issue [PDF]
Tellus A: Dynamic Meteorology and Oceanography, 2003 Can the superensemble methodology provide improved precipitation forecasts by combining existing physical parameterizations? We recently addressed this question in the context of Numerical Weather Prediction (NWP). We feel, however, that the information provided here may be useful for seasonal climate modeling as well.

Convective Quasi-Equilibrium Reconsidered
Journal of Advances in Modeling Earth Systems, 2011 The hypothesis of convective quasi-equilibrium states that moist convection reacts almost instantly to drive the atmospheric temperature profile throughout the troposphere to one of a special subset of possible profiles.

Multi‐Grid Nesting Ability to Represent Convections Across the Gray Zone
Journal of Advances in Modeling Earth Systems, 2019 This study investigated the multi‐grid nesting ability of a limited area model to effectively represent convections across the gray zone, the resolution around 1–10 km where both cumulus parameterization and explicit convection are problematic.

Parameterizing deep convection using the assumed probability density function method [PDF]
Geoscientific Model Development, 2015 Due to their coarse horizontal resolution, present-day climate models must parameterize deep convection. This paper presents single-column simulations of deep convection using a probability density function (PDF) parameterization.

Model Sensitive in Numerical of the Formation of Typhoon Robyn (1993)
Terrestrial, Atmospheric and Oceanic Sciences, 2006 The PSU-NCAR mesoscale model MM5 with an 81-km (27-km) resolution coarse (fine) grid is used to simulate the formation of Typhoon Robyn (1993) in the western North Pacific. This study examines the roles of mesoscale convective system (MCS) during Robyn’s

Sensitivity of Tropical Cyclone Idai Simulations to Cumulus Parametrization Schemes
Atmosphere, 2021 Weather simulations are sensitive to subgrid processes that are parameterized in numerical weather prediction (NWP) models. In this study, we investigated the response of tropical cyclone Idai simulations to different cumulus parameterization schemes ...

A cumulus parameterization with multiple cloud base levels [PDF]
Journal of Geophysical Research: Atmospheres, 1998 We have generalized the Arakawa‐Schubert cumulus parameterization to allow multiple cloud‐base levels. A spectrum of cloud‐top levels is allowed for each cloud‐base level. We use a linear (rather than exponential) mass flux profile, because this greatly simplifies the determination of the entrainment rate and reduces the computational requirements of ...
