Upgrades coming to GFS

[PiedPiper]

Good article @ ars
about upgrades coming the US based GFS forecasting model.

Plenty of more detailed info available here too... via NOAA themselves

Apparently early testing indicates it might take GFS to be the 2nd most accurate model, still lagging behind EC.

Its lagging EC by so far these days, it's desperately needed.
It will be interesting to see how much better it will be.
What's currently #2?

I think they say UKMET is currently the 2nd best.

From the ars article...

For the period of mid-August to mid-September of this year, using this metric, the FV3 model had a score of 0.903 while the operational GFS score 0.897 for the northern hemisphere. For the entire globe, the FV3 had a score of 0.883 and the GFS was 0.872.

The southern hemisphere needs more loving...

I figured it would be. Thanks.
