SUBJECT UPGRADE THE HIRES WINDOW /HIRESW / MODEL TO INCREASE GRIB OUTPUT RESOLUTION… CHANGE GRID SPACING… EXPAND REGIONAL COVERAGE… REVISED RUN SCHEDULE AND RELOCATE
TO THE OPERATIONAL DIRECTORY

EFFECTIVE DATE TUESDAY SEPTEMBER 11 2007

CURRENTLY…THE NATIONAL CENTERS FOR ENVIRONMENTAL PREDICTION /NCEP/ IS PRODUCING
OPERATIONAL RUNS OF THE WEATHER RESEARCH AND FORECAST /WRF/ VERSIONS OF THE
NON-HYDROSTATIC HYBRID VERTICAL COORDINATE MESOSCALE MODEL /NMM/ AND THE NATIONAL CENTER FOR ATMOSPHERIC RESEARCH /NCAR/ ADVANCED RESEARCH WRF /ARW/. THESE RUNS ARE MADE FOR 6 DOMAINS OVER THE UNITED STATES AND PUERTO RICO AND ARE NESTED INSIDE OF THE PARENT NORTH AMERICAN MESO MODEL /NAM/…OBTAINING INITIAL AND BOUNDARY CONDITIONS
FROM THE NAM. BELOW IS THE CURRENT SCHEDULE AND THE SIX ASSOCIATED DOMAINS

0000 UTC ALASKA
0000 UTC HAWAII

0600 UTC WESTERN UNITED STATES /US/
0600 UTC PUERTO RICO

1200 UTC HAWAII
1200 UTC CENTRAL US

1800 UTC EASTERN US
1800 UTC PUERTO RICO

DURING THE TROPICAL SEASON WHEN HURRICANE MODELS ARE RUNNING THE HIRESW RUNS WILL BE CANCELLED ON THE NCEP OPERATIONAL SUPER COMPUTER …BUT ARE RUN ON THE DEVELOPMENT
SUPER COMPUTER WHEN RESOURCES PERMIT.

EFFECTIVE TUESDAY SEPTEMBER 11 2007...THE CHANGES LISTED BELOW WILL BE INCORPORATED INTO
THE HIRESW MODEL.

THE HIRESW WILL BE RUN AT FINER GRID SPACING USING UPDATED VERSIONS OF THE CONSTITUENT FORECAST MODELS. THE GRID SPACING OF THE HIRESW WILL CHANGE FROM 5.15 KM TO 4.0 KM FOR THE WRF VERSION OF THE NMM AND FROM 5.8 KM TO 5.15 KM FOR THE ARW MODEL. ADDITIONALLY… BOTH MODELS WILL BE UPGRADED FROM VERSION 1.3 TO VERSION 2.2 OF THE WRF SOFTWARE.

GRIB OUTPUT PRODUCTS WILL CHANGE FROM 8 KM TO 5 KM GRID SPACING FOR ALL DOMAINS EXCEPT FOR THE ALASKAN WINDOW…WHERE THE GRID SPACING WILL CHANGE FROM 10 KM TO 5 KM. THE REGIONS COVERED BY THE ALASKAN…WEST AND EAST WINDOWS ARE SIGNIFICANTLY INCREASED. THE CENTRAL WINDOW WILL BE ELIMINATED... AS THIS REGION IS WELL COVERED BY THE EXPANDED
WEST AND EAST WINDOWS.

THE REVISED RUN SCHEDULE FOR THE FIVE NEW WINDOW CONFIGURATION IS

0000 UTC EASTERN US
0000 UTC HAWAII

0600 UTC WESTERN US
0600 UTC PUERTO RICO

1200 UTC EASTERN US

1800 UTC ALASKA
1800 UTC PUERTO RICO
