NCEP HiResWindow Forecast Page

NCEP's Environmental Modeling Center (EMC) is making daily runs of the WRF versions of the non-hydrostatic, hybrid vertical coordinate mesoscale model (NMM) and the NCAR Advanced Research WRF (ARW). These are "nested" inside of the parent North American Meso (NAM), getting initial and boundary conditions from the NAM. Currently, five nested domains are being run. The links below will go to a web page with graphics for the most current run for that domain. This is the current schedule:

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

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

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

1800Z : Alaska, Puerto Rico

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

IMPORTANT NOTE : If the NCEP Hurricane model is running for any given cycle, some of all of the operational HIRESW forefcasts will be cancelled by NCEP's Central Operations (NCO). This is production HIRESW configuration when the NCEP hurricane model is running as of 11 September 2007:

No hurricane runs : Both large and small NMM and ARW domains are run by NCO

One hurricane run : Large domain ARW run cancelled by NCO

Two or three hurricane runs : Both large domain NMM and ARW runs cancelled by NCO

Four hurricane runs : All WRF HIRESW cancelled by NCOs

Due to computer resource constraints cancelled HIRESW runs will not be rerun by EMC on the NCEP development computer. Go to the HiResWindow log for the status of the HIRESW runs.

East/Central U.S.; cycle = 2008091512

West/Central U.S.; cycle = 2008091506

Alaska; cycle = 2008091518

Hawaii; cycle = 2008091512

Puerto Rico; cycle = 2008091506

DISCLAIMER : This web page is not "operational" and therefore not subject to 24-h monitoring by NCEP's Central Operations staff.
