I'm more concerned that the Met Office on Jon's example failed also to

pick
out :-

- Trough lying over Western Scotland
- Secondary shallow shallow low Northwest of Scotland
- Wave developing 300miles West of France


LOL, no comment on the superb effort with the low to the east of Iceland ?!

I'd just like to think that the Met Office will not dismiss this as a "Oh
well...." scenario and that they might look into what extra funding,
resources they require in order to bring themselves to anywhere near the
level of consistency and accuracy offered by NOAA.


Presumably you've got the detailed verification to back up that statement,
Andrew ?

It was only a few years ago the MetO GM was deemed (by the NWS) the best
model throughout the entire hurricane forecast season.

Jon.

Oops, sorry Jon, a fantastic forecast for the intensity and location of the
low.

I'm afraid I haven't, I can only go on having seen the models every day for
the past 5 years and IMHO (perhaps I should have said that earlier) that the
GFS is better at mesoscale features.

It was only a few years ago the MetO GM was deemed (by the NWS) the best
model throughout the entire hurricane forecast season.


Jon, that was a few years ago, all the models have changed and developed
since then, I'm talking 2004. I personally feel that around 5 years ago, the
UKMO model took a huge step backwards and has not recovered since, perhaps I
am wrong with this.

I simply feel that at the moment the GFS stands head and shoulders above the
UKMO output, but that is a personal view and I would personally love to see
the opposite being true.

But, like I said, what does the Met Office need in order to do this? I feel
with all the cut-backs, closing of reporting stations etc, the situation is
likely to get worse before it gets better.

Regards,

Andrew

Not mine, but I'll pass on your congratulations. I'll also get that trough
over western Scotland removed at a later date :-)

We've got more reporting stations now than we ever had, many reporting at 10
minute intervals, yes many are automated but the quality is improving all
the time.

Well in my field (aviation) forecasting accuracy is at an all time high so I
beg to differ.

Cheers,
Jon.

How has the number of ships reporting from the Atlantic changed over the
years?

Other than the loss of the weather ships (GACA etc) I doubt it, John.
One thing there is certainly more of is floating bouys.

Thanks, Jon. Are the buoys only in coastal/shallow waters, or are there
some in the middle of the Atlantic as well?

Pretty much all over.

Shows the 0600Z buoy (triangles)/ship (circles) data this morning (note some
decluttering employed).

I may be wrong but my impression is that there were many more SYNOPs
from ships in the 1960s and 1970s than there are today. There were
certainly many more ships plying the oceans 30-40 years ago.

It would seem logical that were more back then, Norman. I was thinking in
terms of the last 10 or so years.
