NOGAPS has been replaced by the NAVGEM

It happened earlier this year:
http://www.nws.noaa.gov/om/notification/tin13-05nogaps_navgem.htm
The new model is the Navy Global Environmental Model (NAVGEM). It may appear as the NOGAPS still on some sites that have yet to update the name. If a site has current data labeled NOGAPS after around late February, it probably is the NAVGEM.
The NAVGEM will not yet appear in the consensus models that the National Hurricane Center put out until they see how it does with hurricanes. That is what they said in last year's 2012 verification report.
"The Navy Global Environmental Model (NAVGEM) will be replacing NOGAPS in 2013, but this model will not be included in the consensus models until its performance for tropical cyclones is better understood."
For now the NAVGEM [GFS tracker] will be available under the same model identifier that the NOGAPS [GFS tracker] came in under in the NHC models:
NGX - NAVGEM [GFS tracker]
NGXI - NAVGEM [GFS tracker] (Interpolated 06 hours)
NGX2 - NAVGEM [GFS tracker] (Interpolated 12 hours)
Models: http://www.hurricanecity.com/models/data.cgi?page=models#NAVGEM-Navy_Global_Environmental_Model
Eventually the "standard Navy tracker data" will come in under "NVGM". NGPS, which was the NOGAPS, will no longer appear. I was curious about that so I asked the NHC.
Also in the 2012 verification report it said:
"Communication problems prevented transmission of NGPS to NHC in 2012. NGXI is computed at NHC using NGPS fields. Historically the performance of NGXI is very similar to NGPI."
I'm not sure if that communication problem is still the case or not. |
