You've gone very quiet Freddie. Still waiting for
some evidence that what you've said happened is
what actually happened.

I wasn't quiet - I have a life beyond this newsgroup.
I have answered your queries in another post.

You have not looked carefully enough and I look at them on every run that I can.


Aahh - we are talking about *analysed* charts - not model runs.


Nope, you've lost me.


the high extended over us from the Azores settled over s, then to our east, then retrogressed, Freddie.


Seriously, if you look at the archive of charts at the link

provided below then you will see that the high didn't regress.

A new one formed in mid atlantic.


I'm open to learning here


Good.


But, on the other hand, you appear not to be.


It would help if you would look back more


carefully at the charts for that period and


provide some learning, if you can, instead of


making simple assertions.


As an exercise for the avid student, please look at the excellent

archive of analysed charts (ASXX archive) at:

Ignore that Freddie. I hit "post" too early, sorry. That's a horrible archive to negotiate. No dates on the thumbnails! Will get back to you later.

Thank you. The archive clearly shows the high centred to our east on the 11th of the month, as it's furthest extent, then pulling back SW (i.e. retrogressing) to lie some distance to our SW by the end of the 16th. I was a day early with my forecast, perhaps, but retrogression, from a high which extended to our east, certainly did happen.

Do look at those charts carefully and please say if you don't see what I do between those dates.

Rubbish. There's a date/time and size underneath the thumbnails and Bernard
even provides arrows for rapid time negotiation after expanding a thumbnail.
It's a superb resource and you could learn a lot from it.

Oh hello.Glad you are following the discussion Will.

Yes. I figured it. I was trying to flick between thumbnails without reading the title and the arrows only move you between the 4 runs on an individual day! Apologies and the resources on Bernard's site are always excellent. See what Freddie's response is - or you could decide to return yourself and comment. I'm sure we'd all be grateful.

But it didn't. The original high decayed and lost identity, and a new
high formed to the south west. If you look at upper air charts for
the same period, then you can clearly see the upper features (that
drive the development and decay of the surface high) behaving in a
way that is conducive to (a) the in-situ high decaying from the
north, its centre drifting S or SSE and eventually losing its
identity; and (b) promoting development of a new high in mid
atlantic. Never forget that the atmosphere is multidimensional and
that the surface charts are only a reflection of what is happening
aloft.

Please look at the charts Freddie. Two questions:


1. On the 11th was the high was centred to our east? You have maintained that this never happened but it clearly was. Surely you can see that?

2. Between the 12th and the 16th, did the high pull back to sit to our SW? Again, you've maintained that this never happened, but the charts clearly show that it did.

The original high decayed and lost identity, and a new

high formed to the south west. If you look at upper air charts for

the same period,


A link would be good. I'd like to see them.

I have never said that this wasn't the case.

I'm sorry but I don't see that in the charts. Additionally the upper
level dynamics (i.e. the existence of a progressive pattern) do not
support regression of surface features.

Can anyone supply Paul a link, please?
