Default Any comments about new resolution GFS?

Since the high res. went operational on 15th I have noticed a tendency to
deepen lows all over the place compared to ECM/UK/JMA. Has anyone else
noticed this? Jon? It is important as such behaviour can cuase big
differences in forecast evolution. E.g. compare T+72s on

Has the model resolution actually changed with this new formulation, Will ?
I ask as Martin's post about it at 1743Z on the 17th didn't appear to
mention any change in resolution.

When Martin first mentioned the parallel suite's availability on Meteociel
some weeks ago I was comparing both outputs as often as I could and I did
wonder if it was more stable from run to run but that's a highly subjective
assessment. I wasn't particularly aware of it overcooking things.

Incidentally, EC's planned resolution upgrade is now scheduled for the 26th
January.

Jon.
