Abstract: OAA NCEP runs a number of numerical weather prediction (NWP) modeling suites to provide operational guidance to the National Weather Service field offices and service centers. A sophisticated infrastructure, which includes ...

Abstract: n initial vortex spindown, or strong adjustment to the structure and intensity of a hurricane?s initial vortex, presents a significant problem in hurricane forecasting, as with the NCEP Hurricane Weather Research and ...

Abstract: his study examines the formation of a double warm-core (DWC) structure in intense tropical cyclones (TCs) that was captured in almost all supertyphoon cases during the 2012?14 real-time typhoon forecasts in the northwestern ...

Abstract: series of 5-day numerical simulations of idealized hurricane vortices under the influence of different background flows is performed by varying vertical grid resolution (VGR) in different portions of the atmosphere with ...

Abstract: AbstractA Gridpoint Statistical Interpolation analysis system (GSI)-based, continuously cycled, dual-resolution hybrid ensemble Kalman filter?variational (EnKF-Var) data assimilation (DA) system is developed for the Hurricane ...

Abstract: his study evaluates the impact of the modification of the vertical eddy diffusivity (Km) in the boundary layer parameterization of the Hurricane Weather Research and Forecasting (HWRF) Model on forecasts of tropical cyclone ...

Abstract: The impact of assimilating Global Precipitation Measurement (GPM) Microwave Imager (GMI) clear-sky radiance on the track and intensity forecasts of two Atlantic hurricanes during the 2015 and 2016 hurricane seasons is ...
