"The model is based on the usual expressions of conservation of mass, momentum, energy and moisture at T1534 spectral truncation, approximately 13 km physics (Gaussian) grid and 64 levels in a hybrid sigma-pressure vertical coordinate. Output is posted to a quarter degree equally spaced longitude/latitude grid with 3-h forecast interval to 240-h, cycled 4X/day, with 46 vertical standard pressure levels."
Très intéressant
Ca y est, la NOAA est arrivée à brancher 2 TI 59 en réseau, avec ça, ça va calculer beaucoup plus vite
https://fr.wikipedia.org/wiki/Texas_Instruments_TI-59
Trève de plaisanteries, 2 messages tombés il y a peu sur la liste, le premier semble concerner des données pour l'aviation qui, à priori ne nous concernent pas, et le deuxième une mise à disposition de nouvelles données pour les brises-glaces (si je comprends bien ?); à regarder de plus près, ça pourrait être amusant pour la Frozen

, mais aucune conséquence non plus à priori.
Soyons cependant vigilants le 7 novembre prochain, aucun changement n'est innocent...

Sujet: Objet: [NCEP.list.NOMADS-ftpprd] Upgrade of LAMP/GLMP to v2.2.1 effective Tuesday 10/22 at 14UTC
NCO is pleased to announce the successful implementation of the Localized Aviation MOS Program (LAMP or LMP) and Gridded LAMP v2.2.1 effective with Tuesday's 14 UTC cycle. Please see attached release notes for full details about the upgrade.
Data is now available on NOMADS and FTPPRD:
https://nomads.ncep.noaa.gov/pub/data/n ... /lmp/prod/
ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/lmp/prod/
and is still available on TGFTP:

Extended ceiling and visibility guidance (out to 38 hours) willassist with Digital Aviation Services and TAF production of 30-h TAFs. Additional stationinputs in GLMP will improve the C&V grids.Developed byNOAA/NWS/Meteorological Development LaboratoryRuns onThe National Weather Service (NWS) Weather and Climate Operational SupercomputingSystem (WCOSS)CommunitysoftwareNoneInputStation observations, satellite data, MRMS, Total Lightning, NAM-MOS, GFS-MOS,ECMWF, RAP, and HRRROutput and whereto find itThe LMP/GLMP products are available on the NWS server.

GFS Verion 15.2 Upgrade
Scheduled Implementation Date: November 7, 2019
A static sample of the new output is available on para nomads:

Removal of vessel icing products, replacement in the GFS
Scheduled Implementation Date: November 7, 2019
The following vessel icing products will be terminated:
sice.tCCz.siceg.grib2
sice.tCCz.siceg_1x1.all.grib2
sice.tCCz.siceg_akw.grib2 Where CC is cycle
from these directories:

https://nomads.ncep.noaa.gov/pub/data/n ... d/sice.YYY YMMDD
https://www.ftp.ncep.noaa.gov/data/nccf ... e.YYYYMMDD Where YYYYMMDD is year, month and day
Users will find the replacement vessel icing product included as a variable (ICEG) in GFS pressure-grid products:
gfs.tCCz.pgrb2.0p25.fFFF
gfs.tCCz.pgrb2.0p50.fFFF
gfs.tCCz.pgrb2.1p00.fFFF Where CC is cycle and FFF is forecast hour
