  1. Project: Influence of Atlantic SST thresholds on continental climates: Development and application of a coupled atmosphere/ocean/vegetation regional climate system model Kerry Cook (PI), Ned Vizy (co-PI) The University of Texas at Austin Development of the RCSM What change would be expected in central U.S. hydrology due to a sudden change in North Atlantic SSTs? Is there potential for abrupt change in central U.S. hydrology due to land surface/ atmosphere feedbacks? Atmosphere: WRFV3, with LSM Ocean: Mixed layer ocean model plus Ekman dynamics (Hagos and Cook 2009) Vegetation: CPTEC PVM (Oyama and Nobre 2004), for now asynchronously coupled Quadrupole Response Current application: Role of atmosphere/land surface interactions in abrupt climate change Application of the atmosphere/LSM/ vegetation version of the RCSM HadCM3 AMJ 850 hPa normalized height difference (A2 2079-99) – (20C3M 1979 – 99)
