Home > HIRESW documentation

The HiresWindow is a dual-core modeling system run at ~3 km horizontal spacing and without parameterized convection. The two dynamical cores are the Advanced Research Weather Research and Forecasting (WRF-ARW) and a limited area configuration of the Finite Volume Cubed Sphere (FV3). This modeling system runs over five different domains on the following schedule:


00Z (CONUS, Hawaii, Guam)
06Z (Alaska and Puerto Rico)
12Z (CONUS, Hawaii, Guam)
18Z (Alaska and Puerto Rico)

The primary WRF-ARW runs for CONUS and Puerto Rico use the Rapid Refresh (RAP) for initial conditions, and the Global Forecast System (GFS) for lateral boundary conditions. The other primary WRF-ARW domains use GFS for both initial and lateral boundary conditions. The second member of the WRF-ARW is initialized from the North America Model (NAM) for both initial and lateral boundary conditions. This second WRF-ARW member is not run for Guam (no NAM coverage for that domain).

All FV3 runs are initialized by interpolation of GFS model output to generate initial and lateral boundary conditions.

The HiresWindow ARW runs are integrated to 48h, while the HiresWindow FV3 is integrated to 60h

The WRF-ARW is developed and supported by the National Center for Atmospheric Research (NCAR), with more information available at https://www.mmm.ucar.edu/weather-research-and-forecasting-model The FV3 dynamical core originated from NOAA/GFDL (https://www.gfdl.noaa.gov/fv3/) and now is part of the broader Unified Forecast System (UFS) (https://ufscommunity.org/)
