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

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 ...

Atmospheric Instability and Its Associated Oscillations in the Tropics

Atmosphere, 2023
The interaction between tropical clouds and radiation is studied in the context of the weak temperature gradient approximation, using very low order systems (e.g., a two-column two-layer model) as a zeroth-order approximation.

The emergence of a new wintertime Arctic energy balance regime

Environmental Research: Climate, 2023
The modern Arctic climate during wintertime is characterized by sea-ice cover, a strong surface temperature inversion, and the absence of convection. Correspondingly, the energy balance in the Arctic atmosphere today is dominated by atmospheric radiative

Vertical Resolution Impacts Explicit Simulation of Deep Convection

Journal of Advances in Modeling Earth Systems, 2023
The aggregation of tropical convection greatly influences the mean‐state of the atmosphere, altering humidity distributions, total atmospheric radiative cooling, and cloud amounts.

Idealized Simulations of the Tropical Climate and Variability in the Single Column Atmosphere Model (SCAM): Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems, 2022
To explore the interactions among column processes in the Community Atmosphere Model (CAM), the single‐column version of CAM (SCAM) is integrated for 1000 days in radiative‐convective equilibrium (RCE) with tropical values of boundary conditions ...

Assessing Memory in Convection Schemes Using Idealized Tests

Journal of Advances in Modeling Earth Systems, 2023
Two assumptions commonly applied in convection schemes—the diagnostic and quasi‐equilibrium assumptions—imply that convective activity (e.g., convective precipitation) is controlled only by the large‐scale (macrostate) environment at the time.
