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.

Modeling the Rise of Fibril Magnetic Fields in Fully Convective Stars [PDF]

, 2016
Many fully convective stars exhibit a wide variety of surface magnetism, including starspots and chromospheric activity. The manner by which bundles of magnetic field traverse portions of the convection zone to emerge at the stellar surface is not ...

Two-Dimensional Hydrodynamic Simulations of Convection in Radiation-Dominated Accretion Disks [PDF]

, 2001
The standard equilibrium for radiation-dominated accretion disks has long been known to be viscously, thermally, and convectively unstable, but the nonlinear development of these instabilities---hence the actual state of such disks---has not yet been ...

Fine Vertical Resolution Radiative‐Convective Equilibrium Experiments: Roles of Turbulent Mixing on the High‐Cloud Response to Sea Surface Temperatures

Journal of Advances in Modeling Earth Systems, 2019
In this study, the vertical resolution dependency of the high‐cloud fraction response on the increase in sea surface temperature was investigated via radiative‐convective equilibrium simulations.

Temperature Fluctuations as a Source of Brown Dwarf Variability

, 2014
A number of brown dwarfs are now known to be variable with observed amplitudes as large as 10-30% at some wavelengths. While spatial inhomogeneities in cloud coverage and thickness are likely responsible for much of the observed variability, it is ...

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

Advanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

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.

Properties, Changes, and Controls of Deep‐Convecting Clouds in Radiative‐Convective Equilibrium

Journal of Advances in Modeling Earth Systems, 2022
Changes in tropical high clouds associated with deep convection with warming are one of the largest sources of uncertainty in climate feedbacks. Here, we leverage an ensemble of models of many types in an idealized configuration to investigate how and ...

Graphene Nanosheet‐Based Mixed Proton‐Electron Conducting Membranes for Efficient Hydrogen Purification

Advanced Functional Materials, EarlyView.
A monolayer graphene/phosphoric‐acid mixed proton‐electron conducting membrane combines proton‐conducting nanoconfined acid channels with electron‐conducting graphene nanosheets for efficient high‐temperature hydrogen purification. The membrane achieves nearly 100% H2/CO2 selectivity and 69 GPU hydrogen permeance at 250°C, arising from synergistic ...

Explicitly Resolved Cloud Feedbacks in the Radiative‐Convective Equilibrium Model Intercomparison Project

Journal of Advances in Modeling Earth Systems, 2023
Radiative‐convective equilibrium (RCE) is particularly well suited for studying tropical deep‐convection, a regime of clouds that contributes some of the highest uncertainties to the estimates of total cloud feedback.
