Quantifying Climate Feedbacks Using Radiative Kernels
Abstract The extent to which the climate will change due to an external forcing depends largely on radiative feedbacks, which act to amplify or damp the surface temperature response. There are aExpand

Using the Radiative Kernel Technique to Calculate Climate Feedbacks in NCAR's Community Atmospheric Model
Abstract Climate models differ in their responses to imposed forcings, such as increased greenhouse gas concentrations, due to different climate feedback strengths. Feedbacks in NCAR’s CommunityExpand

Climate Sensitivity of the Community Climate System Model, Version 4
Equilibrium climate sensitivity of the Community Climate System Model, version 4 (CCSM4) is 3.208C for 18 horizontal resolution in each component. This is about a half degree Celsius higher than inExpand

Radiative forcing and albedo feedback from the Northern Hemisphere cryosphere between 1979 and 2008
The extent of snow cover and sea ice in the Northern Hemisphere has declined since 1979, suggesting a positive feedback of surface reflectivity on climate. A synthesis of a variety of remote sensingExpand

The Evolution of Climate Sensitivity and Climate Feedbacks in the Community Atmosphere Model
AbstractThe major evolution of the National Center for Atmospheric Research Community Atmosphere Model (CAM) is used to diagnose climate feedbacks, understand how climate feedbacks change withExpand

Climate Feedbacks in CCSM3 under Changing CO2 Forcing. Part I: Adapting the Linear Radiative Kernel Technique to Feedback Calculations for a Broad Range of Forcings
AbstractClimate feedbacks vary strongly among climate models and continue to represent a major source of uncertainty in estimates of the response of climate to anthropogenic forcings. One method toExpand

Climate Feedbacks in CCSM3 under Changing CO2 Forcing. Part II: Variation of Climate Feedbacks and Sensitivity with Forcing
AbstractAre equilibrium climate sensitivity and the associated radiative feedbacks a constant property of the climate system, or do they change with forcing magnitude and base climate? Using theExpand

Abrupt Transition to Strong Superrotation in an Axisymmetric Model of the Upper Troposphere
Abrupt transitions to strongly superrotating states have been found in some idealized models of the troposphere. These transitions are thought to be caused by feedbacks between the eddy momentum fluxExpand

Atmospheric response to solar radiation absorbed by phytoplankton
[1] Phytoplankton alter the absorption of solar radiation, affecting upper ocean temperature and circulation. These changes, in turn, influence the atmosphere through modification of the sea surfaceExpand

Climate feedbacks determined using radiative kernels in a multi-thousand member ensemble of AOGCMs
The use of radiative kernels to diagnose climate feedbacks is a recent development that may be applied to existing climate change simulations. We apply the radiative kernel technique to transientExpand
