Abstract: he impact of the North Atlantic Oscillation (NAO) on the Atlantic meridional overturning circulation (AMOC) and large-scale climate is assessed using simulations with three different climate models. Perturbation experiments ...

Abstract: AbstractPrecipitation trends for 1901?2010, 1951?2010, and 1981?2010 over relatively well-observed global land regions are assessed for detectable anthropogenic influences and for consistency with historical simulations ...

Abstract: egional surface temperature trends from phase 3 of the Coupled Model Intercomparison Project (CMIP3) and CMIP5 twentieth-century runs are compared with observations?at spatial scales ranging from global averages to individual ...

Abstract: Evaporative fraction (EF; the ratio of latent heat flux to the sum of the latent plus sensible heat fluxes) can be measured in the field to an accuracy of about 10%. In this modeling study, the authors try to determine to ...

Abstract: The fast and slow components of global warming in a comprehensive climate model are isolated by examining the response to an instantaneous return to preindustrial forcing. The response is characterized by an initial fast ...
