Dal 9 Dicembre il "Nuovo" GFS
Inviato: mer 29 ott, 2014 13:47
Avviso ufficiale dal NOAA : http://www.emc.ncep.noaa.gov/GFS/impl.php
GSM v12.0.0 - implementation scheduled for December 9th, 2014 (subject to change)
Please note: GSM (Global Spectral Model) refers to the forecast component of the larger GFS (Global Forecast System). As the GFS/GSM begins its transition to NEMS/GSM, the terminology will shift as well. See Q1FY16 upgrade for more details on transition of GFS to NEMS.
T1534 Semi-Lagrangian (13km)
More accurate spectral-grid transforms
Reduced grid consistency when creating orographic fields
Use of high resolution daily SST analysis
Use of high resolution sea ice
Physics
Cloud estimate modifications
EDMF parameterization
Dissipation heating paramterization
Convective gravity wave drag
McICA
Modify how GFS diagnoses snow accumulation to be consistent with post
Land Surface - Removal of soil moisture nudging
Unification of analysis ensemble with GEFS ensemble
Ensemble resolution increase to T574L64
Analysis upgrades - See global GSI implementation roadmap
Post Processor
Faster/less memory version
Updated version to use new crtm 2.1.3
add user requested fields
H/T/U/V at FL410,
ozone at 150, 200, 250, 300, 350, and 400 mb,
2m dew point,
wind chill and heat index,
instantaneous precipitation type
membrane SLP in GDAS pgb files
Improved in flight icing algorithm in post
Consolidation of GFS master file creation with GFS DNG, similation of GOES radiances and WAFS
Per ora su meteociel è disponibile il Run parallelo : http://www.meteociel.fr/modeles/gfse_ca ... &runpara=1
