WRF-NMM je mezoskalni prognostički atmosferski model. NMM označava Nonhydrostatic Mesoscale Model, i jezgra je modela WRF koju razvija američki NCEP... Na MeteoAdriatic siteu, WRF se na NMM jezgri starta dva puta dnevno, na 00z i 12z GFS 0.5° početnim i rubnim podacima. Produkti ovog modela osvježavaju se sredinom dana (00z run) i noću (12z run). Simulacija se vrši na tri domene u jednosmjernom gniježđenju (Europa na 36km rezolucije, jugoistočna Europa na 12km rezolucije i Hrvatska na 4km horizontalne rezolucije) sa 45 vertikalnih nivoa. Od veljače 2010. WRF-NMM je u verziji 3.1, sa slijedećom konfiguracijom: Active Domains Domain 01 Domain 02 Domain 03 -------------------------------------------------------------------------------------------------------- Domain & Run Information Primary Time Step : 90 Seconds 30 Seconds 10 Seconds Grid dimentions (NX x NY) : 90 x 140 103 x 178 109 x 196 Vertical Layers (NZ) : 45 45 45 Grid Spacing : 35.70km 11.90km 3.97 km Top of Model Atmosphere : 50mb 50mb 50mb Parent Domain : NA Domain 01 Domain 02 Nesting Feedback : Feedback Off Feedback Off Feedback Off File Output Information File Output Freq : 01 Hour 01 Hour 01 Hour Output File Format : netCDF netCDF netCDF Adjust Ouput Times : Yes Yes Yes Model Physics Dynamics : Non-Hydrostatic Non-Hydrostatic Non-Hydrostatic Cumulus Scheme : Betts-Miller-Janjic Betts-Miller-Janjic None Microphysics Scheme : Ferrier Microphysics Ferrier Microphysics Ferrier Microphysics PBL Scheme : Mellor-Yamada-Janjic Mellor-Yamada-Janjic Mellor-Yamada-Janjic Land Surface Scheme : Noah 4-Layer LSM Noah 4-Layer LSM Noah 4-Layer LSM Number Soil Layers : 4 4 4 Surface Layer Physics : Monin-Obukhov (Janjic) Monin-Obukhov (Janjic) Monin-Obukhov (Janjic) Long Wave Radiation : GFDL Long Wave Rad.
