Abstract:

These are results of the Simulating WAves Nearshore (SWAN) model and the ADvanced CIRCulation (ADCIRC) model simulations to assess the wind, wave and surge impacts of Hurricane Arthur (2014) along the North Carolina (NC) coast. The storm field is constructed by ADCIRC using the parametric Generalized Asymmetric Holland Model (GAHM) forced by modified National Hurricane Center (NHC) advisories. This dataset contain results based on scenarios designed to examine the effects of errors associated with forecast storm track. In these scenarios, we replace the storm strength parameters from the NHC forecast guidance with the same parameters derived from post storm HWind data. The time period of interest is July 1-5 2014, when Hurricane Arthur made landfall in NC.
