Led by Ted Shepherd (Univ. Reading, UK) & Adam Sobel (Columbia Univ., USA)

Aim: Better anticipate how large-scale atmospheric circulation will respond to anthropogenic forcings (GHG, aerosols, ozone).
Focus: Role of local vs large-scale or remotely forced changes in driving regional changes; Identify robust responses; Interpret uncertain components; Assess the impact of model biases or shortcomings on regional responses
