HRES-WAM (High RESolution WAve Model) is coupled to the atmospheric model (HRES) while HRES-SAW (High RESolution Stand Alone Wave model) is run as a standalone model.

HRES-WAM and  HRES-SAW offer the same parameters globally. However, the resolution and the dissemination schedule are different.

Domain

  • HRES-WAM: Global
  • HRES-SAW:  Between latitudes -78 and 90

Both HRES-WAM and HRES-SAW  models computes between the latitudes -78 and 90.  For HRES-WAM, the output grid is artificially extended to -90.

Product resolution

  • HRES-WAM: 0.125° x 0.125° lat/long grid or any multiple thereof (global or sub-area)
  • HRES-SAW: 0.1° x 0.1° lat/long grid or any multiple thereof (global or sub-area)
