NWS is an input in the fort.15 file that selects the meteorological forcing input type. One of the key advantages of ADCIRC is its ability to handle various meteorological input formats or generate tropical cyclone pressure and wind velocity fields from best-track data using internal parametric vortex generation algorithms. Special care must be taken with the selection of the NWS value and associate meteorological input file formats.

Parameter Summary

The following table is a summary of possible NWS values, their description, and associated meteorological input files (required and optional). (this is under development so only showing a few options at present).

NWS Value Short-name Description Required Input Files Optional Input Files
8 Symmetric Holland Vortex Wind velocity and atmospheric pressure are calculated at every node on the fly by ADCIRC internally using the Dynamic Holland model. fort.22 in which its contents correspond to the ATCF Best Track/Objective Aid/Wind Radii Format.
12 OWI ASCII Wind velocities (U10, V10) and atmospheric sea level pressure (SLP) are provided in the OWI ASCII format on one to three rectangular (lat/lon) grid(s) fort.22, fort.221, fort.222 fort.223, fort.224, fort.217, fort.218
