Is it ? I though it was essentially just another model run albeit at a
higher resolution compared to the ensemble, and even the operational
run lowers in resolution at T+180 IIRC.

Either way the GFS appears to be getting all the headlines in this
thread when the best model in terms of medium range deterministic and
ensemble output is ECMWF, IMHO of course but also according to
http://wwwt.emc.ncep.noaa.gov/gmb/ST.../aczhist6.html

Jon.

PS I thought 180C in Exeter was too warm last Thursday, roll on
autumn !


The GFS ensemble gets the headlines on here because the ECMWF ensemble
output isn't put into the public domain as far as I am aware.

Your PS strikes a chord!
