Climate and climate change in a radiative-convective equilibrium version of ECHAM6 [PDF]

open access: yesJournal of Advances in Modeling Earth Systems, 2013
Key Points ECHAM6 is configured to run in RCE with a mixed‐layer ocean RCE similar to tropics in mean vertical structure and overturning circulation Lower climate sensitivity in RCE than in full GCM although feedbacks are present

Can We Use 1D Models to Predict 3D Model Response to Forcing in an Idealized Framework?

open access: yesJournal of Advances in Modeling Earth Systems, 2022
Single‐column models (SCMs) simulations are sometimes used to evaluate model physics and aid parameterization development. However, few studies have systematically compared SCM behavior—where column boundary conditions are specified—with that of ...

Characteristic Form and Distance in High‐Level Hierarchical Structure of Self‐Aggregated Clouds in Radiative‐Convective Equilibrium

open access: yesGeophysical Research Letters, 2022
The nature of convective organization remains elusive, despite its importance in understanding the role of clouds in climate systems. This study reports a new type of large‐scale structure formed by the self‐organization of deep moist atmospheric ...

Cloud‐Radiation Interactions and Their Contributions to Convective Self‐Aggregation

open access: yesJournal 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

Coupled radiative convective equilibrium simulations with explicit and parameterized convection

open access: yesJournal of Advances in Modeling Earth Systems, 2016
AbstractRadiative convective equilibrium has been applied in past studies to various models given its simplicity and analogy to the tropical climate. At convection‐permitting resolution, the focus has been on the organization of convection that appears when using fixed sea surface temperature (SST).

Sensitivity of Convective Self‐Aggregation to Domain Size

open access: yesJournal 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

Structure of the Atmosphere in Radiative–Convective Equilibrium

open access: yesJournal of the Atmospheric Sciences, 2002
Abstract To investigate water vapor transport in an atmosphere in radiative–convective equilibrium, a simplified dynamical convection model (DCM) was constructed that explicitly models moist convection and longwave radiation in a gray atmosphere. In the subsidence region of the equilibrium, atmosphere is predicted by the DCM, dynamical heating, and ...

Ensemble of Radiative‐Convective Equilibrium Simulations Near the Aggregated and Scattered Boundary

open access: yesGeophysical Research Letters, 2021
An ensemble of 10 radiative‐convective equilibrium (RCE) simulations near the sharp transition zone between scattered and aggregated states are examined in a square‐domain cloud‐resolving model.

Clouds and Radiation in a Mock‐Walker Circulation

open access: yesJournal of Advances in Modeling Earth Systems, 2021
The Walker circulation connects the regions with deep atmospheric convection in the western tropical Pacific to the shallow‐convection, tropospheric subsidence, and stratocumulus cloud decks of the eastern Pacific.
