Convective Self‐Aggregation Occurs Without Radiative Feedbacks in Warm Climates

open access: yesGeophysical Research Letters, 2023
Previous research showed that radiative feedbacks are essential to the spontaneous development of convective aggregation (CSA) in idealized atmosphere models.

Radiative Feedbacks From Stochastic Variability in Surface Temperature and Radiative Imbalance [PDF]

open access: yesGeophysical Research Letters, 2018
AbstractEstimates of radiative feedbacks obtained by regressing fluctuations in top‐of‐atmosphere (TOA) energy imbalance and surface temperature depend critically on the sampling interval and on assumptions about the nature of the stochastic forcing driving internal variability.

Radiative feedbacks on global precipitation

open access: yesEnvironmental Research Letters, 2010
The radiative kernel technique is employed to quantify twenty-first century changes to the tropospheric energy budget in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) models in order to better understand changes in global-mean precipitation. The strongest feedbacks on the tropospheric radiative cooling are found to

An Assessment of Direct Radiative Forcing, Radiative Adjustments, and Radiative Feedbacks in Coupled Ocean–Atmosphere Models

open access: yesJournal of Climate, 2015
AbstractIn this study, radiative kernels are used to separate direct radiative forcing from radiative adjustments to that forcing to quantify the magnitude and intermodel spread of tropospheric and stratospheric adjustments in coupled ocean–atmosphere climate models.

A Semi‐Analytical Model for Water Vapor, Temperature, and Surface‐Albedo Feedbacks in Comprehensive Climate Models

open access: yesGeophysical Research Letters, 2023
Radiative feedbacks govern the Earth's climate sensitivity and elucidate the geographic patterns of climate change in response to a carbon‐dioxide forcing.

Radiative Feedback in Galaxies [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractWe examine the fate of ionizing radiation from massive stars on global scales. First, we compare the observed Hα luminosities of LMC Hii regions with those predicted by the latest generation of stellar atmosphere models. Our results imply that classical Hii regions are on average radiation-bounded, rather than density-bounded, as we found a ...

Simulations of galaxy formation with radiative transfer: Hydrogen reionization and radiative feedback [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
We carry out hydrodynamical simulations of galaxy formation that simultaneously follow radiative transfer of hydrogen-ionizing photons, based on the optically-thin variable Eddington tensor approximation as implemented in the {\small GADGET} code. We consider only star-forming galaxies as sources and examine to what extent they can yield a reasonable ...

On the diagnosis of radiative feedback in the presence of unknown radiative forcing [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2010
The impact of time‐varying radiative forcing on the diagnosis of radiative feedback from satellite observations of the Earth is explored. Phase space plots of variations in global average temperature versus radiative flux reveal linear striations and spiral patterns in both satellite measurements and in output from coupled climate models.
