摘要: Abstract Much effort has gone into evaluating the skill of General Circulation Models (GCMs) for ‘standard’ climate variables such as surface (air and/or sea) temperature, or precipitation. Whether model to simulate standard translates performance dynamical GCM forced wind–wave simulations is yet be established. We assess an ensemble historical wave whereby winds taken from GCMs participating in Coupled Model Intercomparison Project (CMIP) are used force a spectral model. The include 8 CMIP5 models and two dynamically downscaled CMIP3 models. climatological properties key integrated parameters (significant height, maximum mean period direction) evaluated, using independent methods, relative three hindcast/reanalysis datasets over 13 areas global ocean. identify that high 'standard' does not imply simulations. also there little no benefit choosing higher resolution (with ∼1.4°) lower (∼2.8°) improve With conscious push towards developing projections waves storm surges aid assessments possible driven impacts coastal communities, we stress need evaluate marine meteorological independently ‘standard' variables.
