But first let me clean up the original to correct the version I may
have posted saome time ago. (Just in case. I think it was a work in
progress though and may have dropped it.)

This is from a weather station near Glasgow:


20th March, 1986

The date of this storm is well documented, many wind speed records
were set in Scotland.


The Burns day storm (25th January, 1990)

It lasted for hours and peaked here around 10pm. 60-70mph �mean� wind
speeds over most of the country, gusts up to and over 100mph.

Other parts of the country suffered far worse. Taking many lives UK-
wide (over 50 deaths) and setting many wind speed records. It was also
one in a line of a few nasty storms that month


The tempest (26th December,1998)

Otherwise referred to as the "Boxing day storm".

The peak of that storm was around 11pm, I recorded a gust of 103mph.
The top ten minute mean wind speed was 56mph, qualifying it for
Overland/Inland storm classification. Around 20% of the mature trees
were down, all uprooted.


Severe Gale of 28th January, 2002

Nothing like as bad as the ones described above in this area, but as
it struck in daylight hours it created it's own brand of headaches and
tragedies. The top gust recorded on my anemometer that day was 74mph.

Sadly there were a few deaths that day, particularly affecting high
sided vehicles which had been blown over on exposed roads

OK.
The hours: 10; 2; 4 and 8 are difficult ones to forecast as I can only
do positive anomaly spells. Those for the hours:
5 and 11 for fine spells
1 and 7 for wet ones
12 and 6 for dull overcast
And 3 and 9 for thundery spells.
(Which of course went haywire this year with its unexplained penchant
for flaccid weather vortexes.)

The other spanner in the works is the minute values of a phase. I have
exactly the same collywabblers with phases that occur on the 20
minutes past or twenty minutes to the hour as I have with those
difficult spells.

However, the difficulty with them all is that they have a tendency to
be flaccid cyclones and anticyclones. And they are associated with
tornadoes. And from what I can see in this PDF, I think a degree of
flaccid pressure systems is endemic:

A historical study of extreme rainfall events in the 20th Century
By W. H. Hand

Abstract
Extreme rainfall events by their very nature are rare but common
enough to require consideration of the possibility and associated
serious flood risk by DEFRA. It is therefore vital that signals of the
likelihood of such events occurring in any given region be recognised
as early as possible, preferably 24 hours or more in advance.

The primary aim of this study was to examine events in the 20th
century in order to ascertain any common hydrological and
meteorological features that could be used operationally to provide
early recognition of the possibility of an extreme rainfall event that
could lead to serious flooding.

The aim of the research was to investigate the nature of very extreme
rainfall events, particularly the meteorological situations leading to
their occurrence and the susceptibility of river catchments.

Rainfall events that give rise to serious flooding involve four main
ingredients. They are intensity and duration of precipitation, the
wetness of the ground and the response of the rainfall catchment. The
key items considered in this study were the first two, which are the
meteorological ones. Hydrological contributions and other factors were
noted when applicable.

A small matter but I suppose I aught to keep it to myself until I
actually take the time to check. I am not even sure what sort of
pressure we have for rainfalls in Britian. Now isn't that omission
strange. I mean it's not something a weather nut would miss is it?

Good job nobody reads my stuff. I'll be pretty miffed if the Lows are
all in the region of 995 to 1005 mb.
