<p>The Grell-Freitas (GF) cumulus parameterization is an aerosol-aware, scale-aware convective parameterization that has been used globally and regionally. This presentation will focus on one of the several developmental activities ongoing in GF: the continued development of its aerosol-aware capabilities and the impact on global forecast

Ongoing Breakthroughs in Convective Parameterization
Current Climate Change Reports, 2019While the increase of computer power mobilizes a part of the atmospheric modeling community toward models with explicit convection or based on machine learning, we review the part of the literature dedicated to convective parameterization development for large-scale forecast and climate models.

Organized Convection Parameterization for the ITCZ*
Journal of the Atmospheric Sciences, 2015Abstract Mesoscale convective systems (MCSs) are of fundamental importance in the dynamics of the atmospheric circulation and the climate system. They are often observed to develop over significant terrain in ambient shear flows in midlatitudes and embedded within the Madden–Julian oscillation (MJO) and convectively coupled equatorial ...

A Parameterization of Slantwise Convection in the WRF Model
Journal of the Atmospheric Sciences, 2022Abstract In this study, we introduce a parameterization scheme for slantwise convection (SC) to be considered for models that are too coarse to resolve slantwise convection explicitly (with a horizontal grid spacing coarser than 15 km or less). This SC scheme operates in a locally defined 2D cross section perpendicular to the deep-layer-averaged ...

The Parameterization of Deep Convection
1997Insights into the parameterization of convection from two decades of diagnostic studies are reviewed. The life cycle of a convective mesosystem mass flux is described using day 245 from the GARP Atlantic Tropical Experiment as example. The thermodynamic differences between non-precipitating convection and precipitating convection are discussed, as well

A Lagrangian Perspective on Parameterizing Deep Convection
Monthly Weather Review, 2019Abstract The parameterization of deep moist convection as a subgrid-scale process in numerical models of the atmosphere is required at resolutions that extend well into the convective “gray zone,” the range of grid spacings over which such convection is partially resolved.

Condensation Parameterization in a Convection Model
1983Condensation is one of the main physical processes which has to be taken into account in atmospheric convection modeling. The problem is treated here with the simplest microphysical approach but with emphasis on the way condensation may be taken into account in subgrid-scale parameterization methods.

Parameterized Slantwise Convection in a Numerical Model
Monthly Weather Review, 1992Abstract A convective parameterization that mimics the theoretical effects of slantwise convection initiated by the release of conditional symmetric instability (CSI) is tested in a three-dimensional primitive equation model. Great positive impact is noted. The scheme is simplest to consider as a Kuo-type convective scheme that operates along (slanted)
