Bells and whistles of convection parameterization [PDF]
Bulletin of the American Meteorological Society, 2013 The present workshop constitutes the 5th in the annual series on “Concepts for Convective Parameterizations in Large-Scale Models”. The purpose of the workshop series has been to discuss the fundamental theoretical issues of convection parameterization with a small number of European scientists.

Considerations for Stochastic Convective Parameterization [PDF]
Journal of the Atmospheric Sciences, 2002 Convective parameterizations in general circulation models (GCMs) generally only aim to simulate the mean or first-order moment of convection; higher moments associated with subgrid variability are not explicitly considered. In this study, an empirically based stochastic convective parameterization is developed that uses an assumed mixed lognormal ...

A new modelling framework for statistical cumulus dynamics [PDF]
, 2011 We propose a new modelling framework suitable for the description of atmospheric convective systems as a collection of distinct plumes. The literature contains many examples of models for collections of plumes in which strong simplifying assumptions are ...

Quantifying the limits of convective parameterizations [PDF]
Journal of Geophysical Research, 2011 [1] Quasi-equilibrium (QE) closure is an approximation that is expected to apply to a large ensemble of clouds under slowly changing weather conditions. It breaks down under rapidly changing conditions or when the domain size is too small to provide an adequate sample of the cloud field.

Journal of Advances in Modeling Earth Systems, 2022 To explore the interactions among column processes in the Community Atmosphere Model (CAM), the single‐column version of CAM (SCAM) is integrated for 1000 days in radiative‐convective equilibrium (RCE) with tropical values of boundary conditions ...

Entrainment Parameterization in Convective Boundary Layers
Journal of the Atmospheric Sciences, 1999 Abstract Various runs were performed with a large eddy simulation (LES) model to evaluate different types of entrainment parametrizations. For this evaluation, three types of boundary layers were simulated: a clear convective boundary layer (CBL), a boundary layer containing a smoke concentration, and a cloud-topped boundary layer. It is shown that the

A Thermal Plume Model for the Martian Convective Boundary Layer [PDF]
, 2013 The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.
