A new operational seasonal forecast system, Japan Meteorological Agency (JMA)/Meteorological Research Institute (MRI) Coupled Prediction System (CPS) version 3 (JMA/MRI–CPS3), has been developed. This system represents a major upgrade of the former CPS2. CPS3 comprises atmosphere, land, ocean, and sea ice models necessary initialization systems for these models. For historical reforecasts, atmospheric reanalysis dataset JRA-3Q provides initial conditions atmosphere external forcings...
Abstract We analyze the performance of European Centre for Medium‐Range Weather Forecasts (ECMWF) and UK Met Office (UKMO) meteorological models in predicting offshore blowing wind coastal areas. Our attention is mainly on Mediterranean coast, up to 200 km distance from shore. compare forecast neutral winds with Advanced Scatterometer measurements. The results indicate that ECMWF forecasts systematically underestimate speed respect scatterometer data, while UKMO model tends overestimate. A...
Abstract The parametrization of orographic drag processes is a major source circulation uncertainty in models. COnstraining ORographic Drag Effects (COORDE) project makes coordinated effort to narrow this by bringing together the modeling community to: explore variety parametrizations employed current operational models; assess resolution sensitivity resolved and parametrized across validate low‐resolution simulations using explicitly from high‐resolution simulations. Eleven models eight...
Abstract It is generally accepted that increased horizontal resolution improves the representation of atmospheric circulation in global weather and climate models. Understanding which processes contribute toward this improvement can help to focus future model development efforts. In study, a set 10‐day forecasts, performed with different orographic resolutions ranging from 180 9 km, are used examine impacts resolving increasingly smaller scales on forecast skill Northern Hemisphere winter...
