Run hwrf using WPS , GFS grib2 data, Prehybrid = NO HWRF F00 forecast vs GFS analysis

Run hwrf using WPS , GFS grib2 data, Prehybrid = NO HWRF F00 forecast vs GFS analysis. Run hwrf using WPS , GFS grib2 data, Prehybrid = NO + Wind speed difference close to 0 + U , V difference still large. Almost same as those using Prehybrid. Wind speed diff. U diff.

Presentation Transcript

  1. Run hwrf using WPS , GFS grib2 data, Prehybrid=NO HWRF F00forecast vs GFS analysis

  2. Run hwrf using WPS , GFS grib2 data, Prehybrid=NO + Wind speed difference close to 0 + U , V difference still large. Almost same as those using Prehybrid. Wind speed diff U diff V diff

  3. Streamlines from original GFS grib2 data file, and original HWRF grib F00 file. HWRF grib F00 GFS grib2 data Shaded is wind speed magnitude HWRF’s Left-bottom streamline is more north than GFS analysis

  4. HWRF 72-hr forecast vs GFS analysis

  5. Run hwrf using WPS , GFS grib2 data, Prehybrid=NO HWRF 72-hr forecast vs GFS analysis The spatial pattern of difference (U, V) is distributed more “randomly” than initial time. Wind speed diff U diff V diff

  6. HWRF grib F72 GFS analysis data HWRF’s Left-bottom streamline is still more north than GFS analysis, but better than initial time.
