Influence of cloud phase composition on climate feedbacks

Low cloud-SST feedbacks influence tropical Pacific climate variability

The remote impacts of climate feedbacks on regional climate predictability

Uncertainty in the spatial pattern of climate change is dominated by divergent predictions among climate models. Model di erences are closely linked to their representation of climate feedbacks, that is, the additional radiative fluxes that are caused by changes in clouds, water vapour, surface albedo, and other factors, in response to an external climate forcing. Progress in constraining this ...

Biophysical Feedbacks on the Regional Climate System

Experiments with coupled atmosphere/biosphere models indicate that land degradation leads to a reduction in rainfall, evapotranspiration, soil moisture and runoff, and an increase in surface temperature and near surface winds. This talk discusses studies that have investigated the feedback of degradation in forest and other ecosystems on regional climate in the Sahel, the central U.S., South Am...

Atmospheric chemistry‐climate feedbacks

[1] We extend the theory of climate feedbacks to include atmospheric chemistry. A change in temperature caused by a radiative forcing will include, in general, a contribution from the chemical change that is fed back into the climate system; likewise, the change in atmospheric burdens caused by a chemical forcing will include a contribution from the associated climate change that is fed back in...

Computing and Partitioning Cloud Feedbacks using Cloud

7 Cloud radiative kernels and histograms of cloud fraction, both as functions of cloud 8 top pressure and optical depth, are used to quantify cloud amount, cloud height and cloud 9 optical depth feedbacks. The analysis is applied to doubled CO2 slab-ocean simulations 10 from ten global climate models participating in the Cloud Feedback Model Intercomparison 11 Project. In the ensemble mean, tot...
