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 coast. The storm field is constructed by ADCIRC using the parametric Generalized Asymmetric Holland Model (GAHM) forced by limited storm information. Dataset includes hindcast results based on the National Hurricane Center (NHC) best track and selected information from the data assimilated HWind product. It also contains forecast results based on NHC advisories 4-12 issued during the storm. The time period of interest is July 1-5 2014, when Hurricane Arthur made landfall in North Carolina.
