What have I been saying. How can these models can give us something
as rare as a similar set up to say 62/63 and then revert back to the
default set up zonal is beyond me.

The 1962/63 "style" set up isn't rare - we still get easterlies these
days in winter, just that they're not particularly cold and don't last
for 3 months on end...!

The thing is Richard, if we know that happens every single time with that
set up why doesn't the very expensive computer model?

One for the researchers to delve into! I guess there are so many
issues in NWP (resolving orography and the effect it has on flows, ice/
liquid microphysics parameterisations, the impact of horizontal and
vertical resolution on forecast accuracy to name but a few) that it's
a case of slowly chipping away at the issues.

It may be that the model does better for other parts of the world.
Getting it right at medium range for the neighbourhood of the British
Isles probably wouldn't have a very high priority for what is after all
an American model.

Quite. I often think the people place unnatural amount of emphasis on
the GFS (and yes I admit to looking at it a lot) just because of the
plethora of data available from it every 6 hours. Don't all the
Metcheck / TheWeatherOutlook types just churn out the GFS output and
make it pretty?

Pity we can't get such regularity of output from UKMET (or at least I
can't find any - maybe it's everywhere on the web these days and I'm
too reliant on Wetterzentrale).
