Dat verklaart dus waarom GFS niet op één lijn zit met EC.
Komt er op neer dat de professionals van NCEP, GFS niet gebruiken omdat dit model een golf mist, waardoor de stroming minder meandert.
Below is the this mornings discussion from the NCEP which is very important to the downstream
synoptics over Europe and the UK.
MODEL DIAGNOSTIC DISCUSSION

...CLIPPER DIVING ACROSS THE MISSOURI VALLEY LATE DAY 1...
PREFERENCE: ECMWF
THE NAM AND GFS LOSE DEFINITION OF THIS WAVE OVER THE MID ATLANTIC STATES BY THE START OF DAY 3. WILL RELY ON THE ECMWF...WHICH HONORS THE TEMPORAL CONTINUITY OF THE IMPULSE BETTER...AND IS SUPPORTED BY BOTH THE GEM GLOBAL AND UKMET.
Commentaar van de poster.
This wave helps keep the pattern amplified meridonal over the states and then merges with another piece of energy further north and helping to send WAA up
in the Greenland area. The GFS model as the discussion says loses this wave of energy and thus keeps a much flatter pattern over the US which of course means a stronger jet coming off of the eastern seaboard of the US into the Atlantic.
