If you are able to, and for the benefit of you and many others, you might
consider killfiling Weatherlawyer. It is only when posters in their replies
fail to snip the c**p that he or she writes that I catch sight of it.

These coastal lows are most common in North America from late fall
thru early spring. They are often not present at all during the summer
when the primary jet stream is far to the north.


It is fairly unusual for an active Low off the east coast of
the USA to reach the UK as a significant feature. *Some ex-hurricanes
may do it but they are re-invigorated over the Atlantic by the
inclusion of cold air from the north. *Our most active Lows usually
form to the southeast of Newfoundland or in mid-Atlantic. *We can get
Lows from anywhere and at any time of year, even occasionally the
northeast. *They are flabby but can be very wet.


Incidentally, low pressure is the one meteorological element
in which the UK trumps the US (except perhaps Florida with its
hurricanes) and every other country except Iceland. The UK record is
925 mb and my personal best is 951 mb, and that in relatively tranquil
south east England.


We have more tornadoes per square mile than any other country. There
are a number of other unique features to UK meteorology too. Not least
the temperate climate. Though I dare say Oregon could argue that.

The path for Lows generally is a spiral (in the right lunar phases
perfectly so) that brings Lows in from Mexico and California
diagonally across the USA and shunts them off into the Atlantic via
Labrador and Newfoundland.

Although this was a trend for much of this winter from the end of
November until that last spell, I confess I have forgotten the effect
that super typhoons have on the system.

When an high is involved it is a little more complicated and Lows tend
to come in from the North East Pacific, Seattle -Oregon and British
Columbia, though I have not followed the path in Canada when that
happens. They do seem to migrate south but overall it is a pall that
covers the continent I think.

This recent disaster mirrored in South America was an odd situation
where a series of Highs did much the same thing as expected of Lows.
Again it was in the absence of severe tropical storms that allowed the
energy free reign.

Not sure how of course. If I were to dare a theory it would be
something along the lines that whilst the O/A pattern is a spiral that
girds the earth almost twice in a cycle from the tropic to the Arctic
Circle, the actual weather induced is following lines of least
resistance.

(Lack of suitable data from Russia and China precludes any follow-up
from me.)

Most interesting is that the pattern is seen reproduced in the obverse
on the surface of the sun. Perhaps in that case we are observing only
the upper atmosphere and must suspect the activity to be anticyclonic.
But I feel it is more likely the result induced by the cause being
focussed on another plane.

If our weather is induced by luni-solar behaviour, it stands to reason
the same effect is visible on the sun, induced by the planets. And
since they all rotate in the same direction as one another....

I googled a bit and saw a diagram/map showing what you wrote about
lows tracking across the North American continent from the Pacific.
Though there is a meterological explanation for all that happens in
weather, I still find this to be amazing.

One more comment. Though you may have more tornadoes per square mile
than any other country, they are puny in comparison to those in the
central and southern USA (this is good thing of course, unless you
enjoy death, chaos and mayhem).

They took the roof off a chapel just up the road from where I used to
live and deposited it on the car of the landlord of a pub across the
road a few minutes after he parked it after a lockin about 2 or 3 am
one night. The town is nestled under an hill about 2 miles from the
sea.

Not much room to build up an head of steam. Quite enough to bowl a
baby across a football field though. How much do you think we need?

http://meteonet.nl/aktueel/brackall.htm is showing a potential
difference of 90 millibars actually more like a hundred on the board
at the moment. Quite a dart board.

I'd say that's a positive anomaly, wouldn't you? Yet the Met Office
have it tracking into the Arctic. If it does, there must be a good
reason for that off the map. Quake or supercyclone or something.

Personally I think it will cross N Scotland or broach at Norway. Vee
schall zee ya?

Meanwhile the smaller cyclone over the Hebrides is responsible (or
coincident as usual, so to speak) for nice weather further down the
country.

Been nice here.

Now let me ask those experts that are too stupid to have me blocked,
why, with a low and a high approaching each other with a difference of
950mb to 1042mb, why don't they run toward each other?

What on earth is that magic antielectropotential or whatever like/
unlike thing that is keeping them apart?

Coriolis effect?

Feckwits!

It is traversing up into the Arctic just as the experts predicted and
I stand corrected....

.....But unbowed

In fact I may have something to redeem myself that might prove useful -
if somewhat subject to permutation, nothing that needs a supercomputer
though.

The course being steered is some 15 degrees from that region of the
Hebrides that, should it receive a low (gale warning in sea areas SE
Iceland/Rockall) provides some nice weather for non haggis eaters.

(Gentlemen in frocks seem to enjoy different tastes in weather to the
rest of us.)

But the point is that should deep lows track around that region by
some 15 degrees the same seems to be true, Britain (or the bits with
people in) tends to get nice weather on such occasions.

I suppose I am being a little previous as the situation may require
super-cyclones to initiate.

Worth watching though.
