a core project of

Radiative Feedbacks

Cecilia Bitz (bitz[@]atmos.washington.edu) and Kyle Armour (karmour[@]u.washington.edu)
The scientific questions that will be studied:
-This theme will investigate radiative feedbacks and their role in polar climates, especially involving sea ice. Central questions for this theme are:
-How do radiative feedbacks depend on processes in the polar regions?
-How does the diversity of polar climate response among models depend on radiative feedbacks?
The processes that will be investigated:
-Radiative feedbacks (Planck, lapse rate, cloud, water vapor, and albedo, each for longwave and shortwave). The non cloud feedbacks can be evaluated for all sky and cloud-free conditions
The type of analyses that will be conducted:
-We will use methods, such as the kernel feedback methods, to compute radiative feedbacks. Radiative forcing will be estimated from fixed SST integrations.
