Convective self-aggregation in numerical simulations: a review [PDF]

Surveys in Geophysics, 2017
Organized convection in the Tropics occurs across a range of spatial and temporal scales and strongly influences cloud cover and humidity. One mode of organization found is “self-aggregation”, in which moist convection spontaneously organizes into one or

Sensitivity of Convective Self‐Aggregation to Domain Size [PDF]

Journal of Advances in Modeling Earth Systems, 2019
A 3‐D cloud‐resolving model has been used to investigate the domain size dependence of simulations of convective self‐aggregation (CSA) in radiative‐convective equilibrium. We investigate how large a domain is needed to allow multiple convective clusters

Congestus Mode Invigoration by Convective Aggregation in Simulations of Radiative‐Convective Equilibrium [PDF]

Journal of Advances in Modeling Earth Systems, 2022
This study examines how the congestus mode of tropical convection is expressed in numerical simulations of radiative‐convective equilibrium (RCE). We draw insights from the ensemble of cloud‐resolving models participating in the RCE Model Intercomparison

Cloud‐Radiation Interactions and Their Contributions to Convective Self‐Aggregation [PDF]

Journal of Advances in Modeling Earth Systems, 2021
This study investigates the direct radiative‐convective processes that drive and maintain aggregation within convection‐permitting elongated channel (and smaller square) simulations of the UK Met Office Unified Model. Our simulations are configured using

The Impact of a Land‐Sea Contrast on Convective Aggregation in Radiative‐Convective Equilibrium [PDF]

Journal of Advances in Modeling Earth Systems, 2023
Convective aggregation is an important atmospheric phenomenon which frequently occurs in idealized models in radiative‐convective equilibrium (RCE), where the effects of land, rotation, sea surface temperature gradients, and the diurnal cycle are often ...

Does convective aggregation need to be represented in cumulus parameterizations? [PDF]

Journal of Advances in Modeling Earth Systems, 2013
Tropical deep convection exhibits a variety of levels of aggregation over a wide range of scales. Based on a multisatellite analysis, the present study shows at mesoscale that different levels of aggregation are statistically associated with differing ...

Convective self–aggregation in a mean flow [PDF]

Atmospheric Chemistry and Physics, 2021
Convective self-aggregation is an atmospheric phenomenon seen in numerical simulations in a radiative convective equilibrium framework thought to be informative of some aspects of the behavior of real-world convection in the deep tropics.
