Stellar Fluxes as Probes of Convection in Stellar Atmospheres [PDF]
, 2006 Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from late-type stars. The theoretical advancements in convection modelling over recent years have proved challenging for the observers to obtain measurements ...

Multiple‐Instance Superparameterization: 1. Concept, and Predictability of Precipitation
Journal of Advances in Modeling Earth Systems, 2019 We have investigated the predictability of precipitation using a new configuration of the superparameterized Community Atmosphere Model (SP‐CAM). The new configuration, called the multiple‐instance SP‐CAM, or MP‐CAM, uses the average heating and drying ...

Role of defects in the onset of wall-induced granular convection [PDF]
, 2015 We investigate the onset of the wall-induced convection in vertically vibrated granular matter by means of experiments and two-dimensional computer simulations.

Reynolds stress models of convection in convective cores [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractWe investigate the properties of non-local Reynolds stress models of turbulent convection in a spherical geometry. Regularity at the centre r=0 places constraints on the behaviour of 3rd order moments. Some of the down-gradient and algebraic closure models have inconsistent behaviour at r=0. A combination of down-gradient and algebraic closures

Convection and Convective‐Organization in Hothouse Climates
Journal of Advances in Modeling Earth Systems, 2023 AbstractIn a “hothouse” climate, warm temperatures lead to a high tropospheric water vapor concentration. Sufficiently high water vapor levels lead to the closing of the water vapor infrared window, which prevents radiative cooling of the lower troposphere.

Journal of Advances in Modeling Earth Systems, 2019 The cloud‐permitting model (CPM) of the superparameterized Community Atmosphere Model (SP‐CAM) is a stochastic parameterization. As reported in a companion paper, we have created a variant of SP‐CAM, called MP‐CAM, that uses the averaged feedback of 10 ...

Fluids, 2019 We study the steady free convective flow of a Bingham fluid in a porous channel where heat is supplied by both differential heating of the sidewalls and by means of a uniform internal heat generation.

Coastal Tropical Convection in a Stochastic Modeling Framework
, 2017 Recent research has suggested that the overall dependence of convection near coasts on large-scale atmospheric conditions is weaker than over the open ocean or inland areas. This is due to the fact that in coastal regions convection is often supported by

Transition to finger convection in double-diffusive convection [PDF]
Physics of Fluids, 2014 Finger convection is observed experimentally in an electrodeposition cell in which a destabilizing gradient of copper ions is maintained against a stabilizing temperature gradient. This double-diffusive system shows finger convection even if the total density stratification is unstable.
