HWRF Components and Libraries

Additional libraries, as described in the HWRF Users Guide, are required.

Update on reduced HWRF v4.0a capabilities

The Hurricane WRF v4.0a public release will have reduced capabilities due to format and library changes impacting input datasets. Starting in January 2021, an update was made to the bufrlib version, impacting input data for data assimilation. Additionally, starting with GFSv16, output will be in NetCDF format, which is not consistent with the released capabilities of HWRFv4.0a. GRIB2 data may be used. Implications of these changes are that HWRFv4.0a cannot run with data assimilation or vortex initialization. Historical cases may still be run using legacy input data formats.
