That appears to be the same model that we were discussing. I believe they renamed the AVN to GFS. Sept-Oct 2002: Name changes: The AVN will be referred to as the Global Forecast System model (GFS). http://wwwt.emc.ncep.noaa.gov/gmb/STATS/html/model_changes.html SUBJECTIVE LIST OF MODEL PERFORMANCE CHARACTERISTICS GFS When specific thresholds in the mass fields are met, convective scheme is triggered and then dumps a large amount of QPF over a grid point - releasing so much latent heat over the grid point that the model is forced to adjust the mass fields by producing a local vertical motion max in the mid troposphere (~ 500mb), a corresponding upper level jet max over the vertical motion max - an intense and small scale vort max in the mid levels (MCV). The model scales up the mesoscale circulation at mid levels and holds onto it as a real feature for as long as 3 days. The model can produce precipitation in association with the feature as it tracks along in the flow. http://www.hpc.ncep.noaa.gov/mdlbias/biastext.shtml#GFS Location in the GOM still bears watching. In case the model might prove correct. But as I stated earlier, and I have rechecked most of the Centers, No One Is Calling For Development Of This Area in the GOM. posted @ 0608Z-02:08 EDT- 0108CDT |
