Past and future wind climates over the contiguous USA based on the North American Regional Climate Change Assessment Program model suite

摘要: [1] Multiple descriptors of wind climates over the contiguous USA from a suite thirteen simulations conducted with five Regional Climate Models (RCMs) nested within reanalysis data and four Global are evaluated relative to North American Reanalysis (NARR) independent observations. Application RCMs improves ‘forecasts’ during 1979–2000 driving reanalysis, exhibit some skill in depicting historical regimes. However, paucity reference sets for represents significant challenge evaluation modeled climates. Simulation intense extreme speeds by are, degree, lateral boundary conditions, instead greater dependence on RCM architecture. that do not employ hydrostatic formulation have higher manifesting macro-scale variability (20 50 year return period) even when applied at spatial resolution km. Output middle current century (2041–2062) indicate evidence lower particularly western U.S., but no difference speeds, 1979–2000.
