Competing effects of surface albedo and orographic elevated heating on regional climate

Geophysical Research Letters, 2017
All else being equal, a given atmospheric pressure level is thought to be warmer over a plateau than over surrounding nonelevated terrain because of orographic “elevated heating.” However, elevated surfaces are also typically brighter due to reduced ...

The climate time scale in the approach to radiative‐convective equilibrium

Journal of Advances in Modeling Earth Systems, 2013
In this paper, we discuss the importance of the surface boundary condition (fixed versus interactive surface temperature) for the long time scale of approach to Radiative‐Convective Equilibrium (RCE). Using a simple linearized two‐variable model for surface‐atmosphere interaction, we derive an analytic expression for τC, a long climate relaxation time ...

Equilibrium Tropical Cyclone Size in an Idealized State of Axisymmetric Radiative–Convective Equilibrium* [PDF]

Journal of the Atmospheric Sciences, 2014
AbstractTropical cyclone size remains an unsolved problem in tropical meteorology, yet size plays a significant role in modulating damage. This work employs the Bryan cloud model (CM1) to systematically explore the sensitivity of the structure of an axisymmetric tropical cyclone at statistical equilibrium to the set of relevant model, initial, and ...

Response of precipitation extremes to warming: what have we learned from theory and idealized cloud-resolving simulations, and what remains to be learned?

Environmental Research Letters, 2020
This paper reviews recent important advances in our understanding of the response of precipitation extremes to warming from theory and from idealized cloud-resolving simulations.

Diurnal Variation of Simulated Cumulus Convection in Radiative-Convective Equilibrium

SOLA, 2018
This study investigates the representation of the diurnal variation of cumulus convection in radiative-convective equilibrium states in an area of 200 km by 200 km without large-scale forcing by using a non-hydrostatic model with sub-kilometer horizontal resolutions.

Tropical cyclogenesis sensitivity to environmental parameters in radiative–convective equilibrium [PDF]

Quarterly Journal of the Royal Meteorological Society, 2007
AbstractIn this study, the relationship between the likelihood of tropical cyclogenesis and external environmental forcings is explored in the simplest idealized modelling framework possible: radiative‐convective equilibrium on a doubly periodic f‐plane.

Coupled radiative convective equilibrium simulations with explicit and parameterized convection

Journal 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).

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Irradiated Atmospheres. III. Radiative-convective-mixing Equilibrium for Nongray Picket-fence Model

The Astrophysical Journal
The nongray picket-fence model predicts more accurately the temperatures in low-density regions compared to semigray models. This study investigates how the vertical-mixing and convection fluxes modify the picket-fence model.
