Spatial patterns of radiative forcing and surface temperature response

Relative roles of surface temperature and climate forcing patterns in the inconstancy of radiative feedbacks

Radiative forcing and climate response

We examine the sensitivity of a climate model to a wide range of radiative forcings, including changes ofsolar irradiance, atmospheric CO2, 03, CFCs, clouds, aerosols, urface •bedo, and a "ghost" forcing introduced at arbitrary heights, latitudes, longitudes, easons, and times of day. We show that, in general, the climate response, specifically the global mean temperature change, issensitive to...

Precipitation, radiative forcing and global temperature change

[1] Radiative forcing is a useful tool for predicting equilibrium global temperature change. However, it is not so useful for predicting global precipitation changes, as changes in precipitation strongly depend on the climate change mechanism and how it perturbs the atmospheric and surface energy budgets. Here a suite of climate model experiments and radiative transfer calculations are used to ...

The Dependence of Radiative Forcing and Feedback on Evolving Patterns of Surface Temperature Change in Climate Models

Experiments with CO2 instantaneously quadrupled and then held constant are used to show that the relationship between the global-mean net heat input to the climate system and the global-mean surface air temperature change is nonlinear in phase 5 of theCoupledModel Intercomparison Project (CMIP5) atmosphere– ocean general circulation models (AOGCMs). The nonlinearity is shown to arise from a cha...

Spatial patterns in Arabian Gulf coral assemblages (Jebel Ali, Dubai, U.A.E.) in response to temperature-forcing

We evaluated spatial and temporal patterns using maps from Ikonos satellite imagery in combination with 8 years of line transects and photosquares and the HadISST1 sea-surface temperature data set to explain why coral assemblages in the southern Arabian Gulf (Dubai) are impoverished and mostly do not build framework reefs. Analysis of archive sea surface temperature (SST) data confirms that the...
