Finer Wind Field Resolution for NWS's Extra-Tropical Storm Surge Model
When the ETSS model was developed it used the finest resolution winds available. Since that time, the GFS model has begun producing wind forecasts on a 0.5 degree wind field, and will soon produce even finer wind fields. MDL recently upgraded the ETSS model to take advantage of the enhanced precision.
This paper will evaluate the benefits of that upgrade, particularly in sheltered regions such as the Chesapeake Bay, Long Island Sound, and Pamlico Sound, where the resolution of the wind field is thought to have the greatest impact on storm surge accuracy.
