Abstract: he climatological storm-track activity simulated by 17 Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4)/phase 3 of the Coupled Model Intercomparison Project (CMIP3) models is compared to that ...

Abstract: his paper applies ensemble sensitivity analysis to a U.S. East Coast snowstorm on 26?28 December 2010 in a way that may be beneficial for an operational forecaster to better understand the forecast uncertainties. Sensitivity ...

Abstract: AbstractEmpirical orthogonal function (EOF) and fuzzy clustering tools were applied to generate and validate scenarios in operational ensemble prediction systems (EPSs) for U.S. East Coast winter storms. The National Centers ...

Abstract: n this study, ensemble sensitivity analysis has been applied to examine the evolution of two extreme extratropical cyclones over the Pacific. Sensitivity using, as forecast metrics, forecast cyclone minimum pressure and ...

Abstract: AbstractThis article introduces a method for objectively separating and validating forecast scenarios within a large multimodel ensemble for the medium-range (3?7 day) forecasts of extratropical cyclones impacting the U.S. ...

Abstract: A significant data void exists in the lower atmosphere during Atmospheric River (AR) events over the northeastern Pacific. When available, AR Reconnaissance data provide the majority of direct observations within the ...
