Seeing the alternative Beaufort scale thread. Anyone know of a resource
where there is hints at converting reported events to wind strengths?
3 reported events, none of them recent.
A 6 x 4 foot steel old-style advertising hoarding plate ripped off a
building and clean slicing through 15 inch diameter trunk of a larch
tree 100 yards away.

Lead flashing strip, 8x1 foot ripped off a roof and landing 250 yards away.

4 foot long, 1.5x1.5 inch sawn timber, plain faced sawn ends, being
punched cleanly through both side walls of an inflated car tyre.

In Shetland that would be gale force 8 :-)

The first 2 were almost certainly the result of individual gusts. The Beaufort
Force can't be deduced from those. My guess is that the 3rd one occurred in a
hurricane.

Our local marine basic weather+tides reporting station , VTS Southampton
www.sotonmet.co.uk
, reports 2 figures for wind strength, eg for Imogen passing logally
F7/F9 meaning Beaufort 7 for some sort of average strength, and 9 for
some sort of gust strength, so I presumed there was some sort of, at
least rule of thumb , relation.

I've had a look at that link. The display is incorrect in that it assigns
Beaufort Forces to the gust speeds. By definition, Beaufort Forces apply only to
mean wind speeds. For example, if the mean wind speed was in the range 22-27
knots with gusts to 35 knots, it would be correct to describe it as 'Force 6
with gusts to 35 knots'. It would be incorrect to describe it as 'Force 6
gusting to Force 8' because what that would actually be saying is 'a mean speed
of 22-27 knots gusting to a mean speed of 34-40 knots' which is clearly not the
case.

Mean speed to gust ratios are very site-specific depending on exposure and local
surface roughness. They also vary considerably with varying low-level
atmospheric stability.

Guns'n'ammo will have something somewhere. There is a German hobbyist that messes around with something in the bows and arrows line, that mucks around with something like that on You Tube; no link, sorry.

Meanwhile while I am in a mood to be depressing:
2016-02-08 @ 16:19 (6.5 BOUGAINVILLE P.N.G.) to
2016-02-10 @ 00:33 (6.3 COQUIMBO, CHILE) is something like eight plus twenty four hours which if you allow something in the region of a Froude number each three hour interval between significant earthquake, equates to 10 Beaufort scale numbers at sea level somewhere in a couple of weeks.

I can wait. I don't have much choice. Brain like a computer and all it can do is make remarks on graphics. Is this what they call life?

I don't know.
