Radiative–convective equilibrium model intercomparison project [PDF]
Geoscientific Model Development, 2018 RCEMIP, an intercomparison of multiple types of models configured in radiative–convective equilibrium (RCE), is proposed. RCE is an idealization of the climate system in which there is a balance between radiative cooling of the atmosphere and heating ...

Self-aggregation of clouds in conditionally unstable moist convection [PDF]
Proceedings of the National Academy of Sciences, 2011 The behavior of moist Rayleigh–Bénard convection is investigated using a Boussinesq model with a simplified thermodynamics for phase transitions. This idealized configuration makes the problem accessible to high-resolution three-dimensional direct numerical simulations without small-scale parameterizations of the turbulence for extended layers with ...

A simple model linking radiative–convective instability, convective aggregation and large-scale dynamics [PDF]
Weather and Climate DynamicsA simple model is presented which is designed to analyse the relation between the phenomenon of convective aggregation at small scales and larger-scale variability that results from coupling between dynamics and moisture in the tropical atmosphere.

A Shallow-Water Model for Convective Self-Aggregation
Journal of the Atmospheric Sciences, 2020 AbstractRandomly distributed convective storms can self-aggregate in the absence of large-scale forcings. Here we present a 1D shallow-water model to study the convective self-aggregation. This model simulates the dynamics of the planetary boundary layer and represents convection as a triggered process.

Vertically resolved weak temperature gradient analysis of the Madden‐Julian Oscillation in SP‐CESM
Journal of Advances in Modeling Earth Systems, 2016 The collective effects of convection can influence large‐scale circulations that, in turn, act to organize convective activity. Such scale interactions may play an important role in moisture‐convection feedbacks thought to be important to both convective

Aerosol‐Cloud‐Precipitation Interactions in the Context of Convective Self‐Aggregation [PDF]
Journal of Advances in Modeling Earth Systems, 2019 AbstractWe investigate the sensitivity of self‐aggregated radiative‐convective‐equilibrium cloud‐resolving model simulations to the cloud condensation nuclei (CCN) concentration. Experiments were conducted on a long (2,000‐km × 120‐km) channel domain, allowing the emergence of multiple convective clusters and dry regions of subsidence.

The Role of Interactive SST in the Cloud‐Resolving Simulations of Aggregated Convection
Journal of Advances in Modeling Earth Systems, 2019 This study investigates the role of interactive sea surface temperature (SST) in the early development of aggregated convection using a vector vorticity equation cloud‐resolving model coupled to a slab ocean.

Journal of Advances in Modeling Earth Systems, 2022 We propose a parameterization scheme of convective organization effects based on a moisture‐distribution approach, which can reflect aggregation of convective cells within a model grid as well as the interaction between convection and spatial ...

Journal of Advances in Modeling Earth Systems, 2017 WTG balance is used to examine how changes in the moist thermodynamic structure of the tropics affect the MJO in two simulations of the Superparameterized Community Earth System Model (SP‐CESM), one at preindustrial (PI) levels of CO2 and one where CO2 ...
