DATA MGT MESSAGE 06-02.16

ATTN       USERS OF PRODUCTS OR SERVICES

FROM       THE NWS TELECOMMUNICATION GATEWAY OR RTH
                WASHINGTON

SUBJECT UPGRADE OF THE MODEL USED IN THE HI-RES WINDOW RUNS
FROM HYDROSTATIC MESO ETA TO NON-HYDROSTATIC MESO MODEL
/NMM/ AND INCREASE RESOLUTION FROM 10 KM TO 8 KM AND
RELOCATE TO A TEST/NON-OPERATIONAL DIRECTORY

THE HI-RES WINDOW RUNS PROVIDE HIGHER RESOLUTION RUNS AT
LEAST ONCE EACH DAY /WHEN THERE ARE NO TROPICAL CYCLONES/
FOR ALL OF THE US THAT ALLOWS USERS THE OPPORTUNITY TO
PREVIEW UPCOMING CHANGES TO THIS MODEL AND ITS
RESOLUTION.  THIS CHANGE INCREASES THE HORIZONTAL
RESOLUTION FOR ALL HI-RES WINDOW DOMAINS 10 KM TO 8 KM
EXCEPT FOR ALASKA WHICH WILL INCREASE FROM 12 KM TO 10 KM.
WITH RESOLUTIONS BECOMING FINER THAN 10 KM THERE IS A NEED
TO GO BEYOND SIMPLE HYDROSTATIC MODEL DYNAMICS.  THE
NON HYDROSTATIC MESO MODEL /NMM/ DOES THIS IN A VERY
EFFICIENT WAY WHILE MAINTAINING NEARLY IDENTICAL PHYSICS
CODE WITH THE OPERATIONAL 12 KM MESO ETA MODEL.
