I have a question that I hope to gain consensus on. In speaking with a friend from NCEP over winter break, he kept reminding me on how the AVN was now called the GFS. Is it truly the same model? Also, is the MRF now also considered the GFS.
Technically, NCEP eliminated the MRF model 12 months ago. At the same time, they added resolution to the AVN and named it the GFS. Currently, NCEP still uses the old model designations in the GRIB files. If you look at the MRF grids out to 5 days, they match the equivalent AVN grids. So there is overlap. I've gone to naming the grids GFS/AVN and GFS/MRF for both forward and backward compatibility. -- ________________________________________________________ Daniel Vietor Mail: devo@xxxxxxxxxxxxx Unisys Corp Title: Engineer/Meteorologist 221 Gale Lane Phone: 610-925-5206 Kennett Square PA 19348 Fax: 610-925-5215
