Branstator, Grant

Focus on problems in large scale atmospheric dynamics, and on the predictability of the coupled ocean-atmosphere system. Work to characterize the processes that organize midlatitude tropospheric variability on monthly and longer timescales - influence of land-sea contrasts, the synoptic eddies and tropical sea surface temperature anomalies. Prominent intrinsic modes of variability of the atmosphere; quasi-linear models, stochastic methods, the fluctuation dissipation theorem, and analog techniques.

Simpson, Isla

Large scale atmospheric dynamics and its representation in global climate models. Work to understand dynamical mechanisms involved in the variability and change of the large scale circulation and its impacts on regional climate and hydroclimate using a hierarchy of modelling approaches. Aim to determine the extent which models can successfully capture the processes of relevance for the real atmosphere and how they can be improved.
