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).
