I will also add the model terrain or model topography of the GFS, GEFS and HRES ECMWF. The borders are not a part of the model output. I added the county borders myself, to compare the model terrain to actual borders.
First ECMWF, which despite having a few km lower resolution, has a much smoother terrain and a better representation than GFS. Not to mention the sub-grid orography module.
Next is the new GFS. Quite an improvement from the old one.
And then we have GEFS A and B. A is the configuration that goes to 180h, and B goes from 192-384h. Both versions, especially the B, have a bit of a problem with the representation of Alps. That is one of the reasons why GEFS usually draws perfect secondary cyclogenesis scenarios in the 192-384h and removes them when it gets into the better resolution.
I plotted the data from the SFLUX files of GFS, SFC Analysis for ECMWF and PGRB files for GEFS.
