Improvements to Stellar Structure Models, Based on a Grid of 3D Convection Simulations. I. $T(\tau)$-Relations [PDF]
Relations between temperature, T, and optical depth, tau, are often used for describing the photospheric transition from optically thick to optically thin in stellar structure models.

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 ...

The Impact of a Land‐Sea Contrast on Convective Aggregation in Radiative‐Convective Equilibrium
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 ...

Convective cores in galactic cooling flows [PDF]
We use hydrodynamic simulations with adaptive grid refinement to study the dependence of hot gas flows in X-ray luminous giant elliptical galaxies on the efficiency of heat supply to the gas. We consider a number of potential heating mechanisms including

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

Self-Organization of Atmospheric Macroturbulence into Critical States of Weak Nonlinear Eddy–Eddy Interactions [PDF]
It is generally held that atmospheric macroturbulence can be strongly nonlinear. Yet weakly nonlinear models successfully account for scales and structures of baroclinic eddies in Earth's atmosphere.

Sensitivity of Convective Self‐Aggregation to Domain Size
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

The Stagger-grid: A Grid of 3D Stellar Atmosphere Models - I. Methods and General Properties [PDF]
We present the Stagger-grid, a comprehensive grid of time-dependent, 3D hydrodynamic model atmospheres for late-type stars with realistic treatment of radiative transfer, covering a wide range in stellar parameters. This grid of 3D models is intended for

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