Statistical Parameterization of Heterogeneous Oceanic Convection
Journal of Physical Oceanography, 2007Abstract A statistical convective adjustment scheme is proposed that attempts to account for the effects of mesoscale and submesoscale variability of temperature and salinity typically observed in the oceanic convective regions. Temperature and salinity in each model grid box are defined in terms of their mean, variance, and mutual ...

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 ...

Non-precipitating cumulus convection and its parameterization
Quarterly Journal of the Royal Meteorological Society, 1973AbstractThis paper discusses the thermodynamic transports of heat, liquid water and (briefly) water vapour by non‐precipitating cumulus convection. It is shown that because of the irreversible mixing between cloud and environment, there is a downward transport of enthalphy in the cumulus layer.

Numerical Archetypal Parameterization for Mesoscale Convective Systems
Journal of the Atmospheric Sciences, 2016Abstract Vertical shear commonly organizes atmospheric convection into coherent multiscale structures. The associated countergradient vertical transport of horizontal momentum by organized convection can enhance the wind shear and transport kinetic energy upscale.

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.

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

Using Deep Learning for Convection Parameterization
Data-driven approaches using machine learning to parameterizing model physical processes in Earth System Models have been actively explored in recent years. Deep-learning-based convection parameterization is one such example. While significant progress has been made in emulating convection using neural networks (NN), serious roadblocks remain ...Guang Zhang, Yilun Han, Yong Wang

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)
