Clouds, Circulation, and Climate Sensitivity in a Radiative‐Convective Equilibrium Channel Model

open access: yesJournal of Advances in Modeling Earth Systems, 2017
Tropical cloud and circulation changes are large sources of uncertainty in future climate change. This problem owes partly to the scale separation between large‐scale tropical dynamics ( ∼104 km) and convective dynamics ( ∼1 km), which generally requires

Atmospheric Instability and Its Associated Oscillations in the Tropics

open access: yesAtmosphere, 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.

Radiative Convective Equilibrium and Organized Convection: An Observational Perspective [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2019
AbstractRadiative convective equilibrium (RCE) describes a balance between the cooling of the atmosphere by radiation and the heating through latent heat release and surface heat fluxes. While RCE is known to provide an energetic constraint on the atmosphere at the global scale, little is known about the proximity of the atmosphere to RCE at smaller ...

The emergence of a new wintertime Arctic energy balance regime

open access: yesEnvironmental 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

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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.

Radiative convective equilibrium over a land surface

open access: yesJournal of Climate, 2014
Radiative-convective equilibrium (RCE) describes an idealized state of the atmosphere in which the vertical temperature profile is determined by a balance between radiative and convective fluxes. While RCE has been applied extensively over oceans, its application over the land surface has been limited.

Eddy Influences on Hadley Circulations: Simulations with an Idealized GCM [PDF]

open access: yes, 2006
An idealized GCM is used to investigate how the strength and meridional extent of the Hadley circulation depend on the planet radius, rotation rate, and thermal driving.

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 ...
