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.

Idealized Mesoscale Convective System Structure and Propagation Using Convective Parameterization
Monthly Weather Review, 2008 Abstract The development and propagation of mesoscale convective systems (MCSs) was examined within the Weather Research and Forecasting (WRF) model using the Kain–Fritsch (KF) cumulus parameterization scheme and a modified version of this scheme.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Long‐term disdrometer observations are utilized to derive Z–R relationships for ‐the Western Pacific tropical cyclones. A hybrid moment‐based approach is employed to determine the interrelationships among pairs of gamma distribution parameters. Enhanced estimates of rainfall rate and slope parameter are obtained using machine‐learning techniques ...

Impact of small‐scale gravity waves on tracer transport
Quarterly Journal of the Royal Meteorological Society, EarlyView.We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.

Sensitivity of a Mediterranean Tropical-Like Cyclone to Physical Parameterizations
Atmosphere, 2018 The accurate prediction of Mediterranean tropical-like cyclones, or medicanes, is an important challenge for numerical weather prediction models due to their significant adverse impact on the environment, life, and property.

Feedback Processes and Climate Response [PDF]
, 1990 The response of the climate system to an external perturbation--e.g., a change in solar irradiance or a change in atmospheric opacity due to an increase in CO2--depends rather strongly on feedback processes in the system, which either amplify or dampen ...

Symmetry preserving parameterization schemes
, 2012 Methods for the design of physical parameterization schemes that possess certain invariance properties are discussed. These methods are based on different techniques of group classification and provide means to determine expressions for unclosed terms ...

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Regional modelling of tracer transport by tropical convection – Part 1: Sensitivity to convection parameterization [PDF]
Atmospheric Chemistry and Physics, 2009 The general objective of this series of papers is to evaluate long duration limited area simulations with idealised tracers as a tool to assess tracer transport in chemistry-transport models (CTMs).
