Impact of cloud parameterization on the numerical simulation of a super cyclone [PDF]
Annales Geophysicae, 2012 This study examines the role of parameterization of convection and explicit moisture processes on the simulated track, intensity and inner core structure of Orissa super cyclone (1999) in Bay of Bengal (north Indian Ocean). Sensitivity experiments are

Spectral cumulus parameterization based on cloud-resolving model [PDF]
Climate Dynamics, 2018 We have developed a spectral cumulus parameterization using a cloud-resolving model. This includes a new parameterization of the entrainment rate which was derived from analysis of the cloud properties obtained from the cloud-resolving model simulation and was valid for both shallow and deep convection.

Shallow convective closure in a spectral cumulus parameterization
Atmospheric Research, 2020 Abstract A shallow convective closure (shallow closure) was introduced in a spectral cumulus parameterization (spectral scheme), and the validity was evaluated using an atmospheric general circulation model (AGCM) and Atmospheric Model Intercomparison Project (AMIP) experiments.

Influences of an entrainment–mixing parameterization on numerical simulations of cumulus and stratocumulus clouds [PDF]
Atmospheric Chemistry and Physics, 2022 Different entrainment–mixing processes can occur in clouds; however, a homogeneous mixing mechanism is often implicitly assumed in most commonly used microphysics schemes.
