NCEP HiResWindow Forecast Page

The NCEP High-Resolution Window Forecast System (HIRESW) consists of daily runs of the WRF versions of the non-hydrostatic, hybrid vertical coordinate mesoscale model (NMM) and the NCAR Advanced Research WRF (ARW) at ~5 km resolution. All runs except the Alaska domain use the NAM for initial and boundary conditions. The Alaska run uses the NCEP Global Forecast System (GFS) for initial/boundary conditions. Currently, six nested domains are being run, three large domains (East/Central U.S., West/Central U.S., Alaska) and three small domains (Hawaii, Puerto Rico and Guam). This is the current schedule:

0000Z : East/Central U.S., Hawaii, Guam

0600Z : West/Central U.S., Puerto Rico

1200Z : East/Central U.S., Hawaii, Guam

1800Z : Alaska, Puerto Rico

Modifications to the HiResWindow runs are described in the EMC Mesoscale Branch's documentation of model changes.

IMPORTANT NOTE : Some or all of the operational HIRESW runs are canceled if the NCEP Hurricane Model is run. As of 7/06/10, this is the production HIRESW configuration when the NCEP hurricane model is running:

Two or less hurricane runs : All HIRESW runs are made

Three or four hurricane runs : Both Large domain NMM and ARW runs canceled

Five or more hurricane runs : All HIRESW runs canceled (except for Guam)

Go to the HiResWindow log for the status of the HIRESW runs.
