So is that a tacit admission that the ECMWF is the best?

Thanks for the link,

Looks like it, cunningly disguised by choosing a graph format where they
don't have to include an explicit line for it. It's interesting that
the ECMWF seems to have been further improved around July last year, as
most of the other models seem to dip in relation to it from then on. I'm
surprised that the German model seems to be worst by a wide margin; I
thought the Germans were good at everything.

Thanks for the link,

And thanks from me too.

I'm not sure why that should be.

Interesting how the Euro4 model doesn't really extend that far upstream of the British Isles. Clearly they must believe that the 25km/70 levels is adequate to capture any naughty 1987 storm type developments before they reach the British Isles before the storms shift into the 4km domain.

.... The truncation was probably forced by resource limitations but it
occurs to me that it might help with the 'over-cooking' of the
latent-heat exchanges that the finer-meshed models have problems with:
if the "model low" spends less time over the ocean, it has less (model)
time to pick up and convert humidity to sensible heat and over-drive the
pressure falls in a depression?

Well the graph contained within the linked to document appears to show
that it is.

Ah, I see. Sorry. I misinterpreted what you were saying.

Isn't it all down to a better analysis?
