I just noticed the similarities in these runs:

But then there is this one

14th to 21st March 2008. The time of the phase is 10:46. Which is
similar to the last phase, in that it should provide anticyclonic
weather.

However things are not working out that way so far.

So here we are 5 minutes into a new spell and things are looking
exactly the same as they did at the start of the last:
http://weather.unisys.com/images/sat_sfc_map_loop.html

I don't know what's going on over Oklahoma, Arkansas, Texas and
Louisiana. There is nothing on this site to compare to the yellow
squares on the above site:
http://www.spc.noaa.gov/products/wwa/

But there is a lot of cyclogenesis (stormy weather) there.

Points to watch out for:

On the NEIC board that lists the dates of recent earthquakes with a
magnitude over 5:
http://earthquake.usgs.gov/eqcenter/...quakes_big.php

Look out for a day that reports no such quakes. This is a new thing
learned so it might contain errors but it seems that when there are
violent storms due whose potential inner pressures at sea level are
likely to be as low as the 960's millibars,

.....there is always an hiatus in the list.

I have noticed the hiatus in times past but never made the connection
until looking at the Aussie site he
http://www.bom.gov.au/cgi-bin/nmoc/l...DCODE=IDX0033&...

And following this warning is a much less gentle one where there will
be two or three consecutive earthquakes on that list that are in
almost the same place. I am not sure where the first series takes
place but the same recurs when the storm is over and the following
seems to apply:

Not quite.

But close. Seasoned Weatherlawyer fans will be keeping notes on this
sort of thing.
I only wish I was as sensible.

For storms in the South West Indian Ocean, this series seems to be
Vanuatu some 120 degrees distant.

I expect yet more tropical storms and there is still the residue of
the storm that passed through Britain last Monday to fade into the
background too.

That one is at present over Estonia and Latvia, with the one that
crossed Britain a day or so later about to approach Norway both at 990
millibars.

I believe that when they reach 1000 to 1005 mb there will be a large,
maybe a very large earthquake. (As a warning the prelude will be some
uncertain or plain wrong weather forecasting from the various national
agencies.)

So the next spell but one will be very similar to the last one, the
present spell will be virtually the same as the next and the last in
the series will not be totally dissimilar to the pair.

And I am somewhat at a loss to forecast any of them.
Or not, as the case appears to be.
Interesting, no?

Snels' Law. Sometimes called: Snellius Descartes' law:

"The law says that the ratio of the sines of the angles of incidence
and of refraction is a constant that depends on the media.
In optics, the law is used in ray tracing to compute the angles of
incidence or refraction, and in experimental optics to find the
refractive index of a material."

http://en.wikipedia.org/wiki/Snell's_law

Now, suppose that the angle of incidence is that of gravity acting
upon the gyroscope; earth. It stands to reason that glitches in the
dissipation of gravitational attraction will show up in the inertia of
large bodies as some sort of streak through any set up harmonic.

But before considering what that might be one has to consider the
harmonic as a period in stasis. At any particular frozen moment, the
moon is acting upon the earth according to geometrical progressions
noted by Newton.

However arbitrary departures from these geometric progressions are
caused by the unevennesses of both the surface of the moon and the
surface of the earth. As the masses of both celestial spheres is too
great for comparatively minor errors in escapement of the mechanism,
the system has to divest itself of the energy differential somehow
other than as celestial dynamics.

It is this transduction of forces that powers stellar systems. And on
earth causes earthquakes and weather.

And it is the angles of incidentae and refractions that concern the
mathematical deduction of the likely whereabouts of the relevant
geophenomena.

But I don't have a clue how to get at it. I wouldn't know how to
resolve the angle that storms and earthquakes make on the surface of
the earth. And I don't know if I should be looking at sines or
cosines.

For all I know I aught to be looking at tangents. It certainly seems
more appropriate, considering orbit and the rest of it. Ah well, off
to bed I think .....and maybe dream.

There is a well defined Low over the states surrounding the Great
Lakes. There has been a continuous stream of low weather crossing the
USA in a belt from California to virtually all the eastern states and
building up there.

Meanwhile in the Western North Atlantic there is a pretty well marked
region of not very low Low pressure. Whilst in the east the pressure
are more normal.

So all in all, I'd say that Hawaii is going to get a lot more volcanic
action this week.
The report from the Smithsonian will be out late tomorrow. So will the
lava.

This flaccid pressure system has spread across the North Atlantic.

A deep low on the TLH of this map:
http://www.weatheroffice.gc.ca/data/analysis/947_50.gif
yesterday (1st April 08) spread out to cover half the northern neck of
the North Pacific by today (the 2nd.)

Is this indicative of further eruptions at Hawaii or is it a normal
characteristic of most Lows as they leave a continental land mass. The
pressure is still low 971mb but it was 954mb yesterday.

There is an anticyclone now in almost exactly the same position the
low was in the other day.

I took a look at some of the synoptic charts for this spell and it
appears that there is an oscillation on all the bases where an High is
replaced by a Low and a Low by an High.

I never noticed that before. It may be that i am not an acute observer
of geophysical phenomena. Or it may be a phenomena peculiar to the
vulcanicity of the present cycle.

I would have noticed any peculiarities on the Atlantic Chart and I
did! So maybe this is a special.

Or maybe it is a reason why I have such problems with these times?
21:47 as near to 22:00 or 10 o'clock as damn it is to swearing.
I never liked them.

And there's loads this year, too, neither!

I'll put the rest up at the end of the spell. Or this particular part
of the run.

Quake warning or what? I forget what portends with these.

End of a tropical storm IIRC but there hasn't been one. A deep low in
the NW Pacific?

No deep lows in the N Pacific, in fact both oceans are very negative
with a low of 1004 and an high of 1014 in the EN Pacific and a series
of not very low Lows each side of the large High around Greenland.

Looks like there is a fair bit of volcanic activity "in the air".

Any storms in the North Pacific will take the detritus straight into
the Arctic. Detritus from the late 19th century indicates the ash was
rich in trace metals so there is the source of the rich marine life to
be found at the fishing grounds where the Arctic drains.

What explorers saw off Greenland: Haze and dust
"The sky was covered with thin veil of clouds, through which the
sun shone warmly, at times even scorchingly. From time to time this
veil of clouds, or haze, descended to the surface of the ice, and hid
the view over the expanse; but it was, remarkably enough, not wet, but
dry - yes, so dry that our wet clothes absolutely dried in it."

Could it be that it only takes a variation of 1mb for a high pressure
to be changed to a low pressure on the chart? The system has remained
in the same position and has altered it's characteristics marginally,
but its meteorological name has changed, as it has crossed that
arbitrary 1013mb, average atmospheric pressure, threshold?

Before I welcome you to the group I aught to warn you that there is a
tendency to besmirch anyone looking for answers on here.

Welcome to the group.

I have not really looked at the chart in any detail. They almost
never, ever change as quickly and as unexpectedly as they seem to be
doing in this spell. A spell usually runs the length of time it takes
for the moon to run 90 degrees. (No idea why, it is just.. so.)

An anticyclone runs clockwise IIRC and a cyclone runs the other way.
Looking down from the N Pole you would see the earth spinning from
Greenwich to what used to be New Orleans to Fiji to Calcutta to
Greenwich.

That is a cyclonic direction. Maybe it is why there is a tendency to
anticyclones in the Arctic. But going through the planet it would make
Antarctica tend to anticyclones wouldn't it? So it isn't that.

Of course with a weak set up the wind directions in reality can be
difficult to ascertain.
Fortunately one of us thinks he has discovered another tool in the
shed:

The figures represent:
Magnitude; date; time; co-ordinates; depth and general location. The
last three represent when the Low was rather deep IIRC though I aught
to go and look at my collection to make sure.

Pity I am so lax that I won't.

When a Low lapses it is shown as wide apart bands of pressure lines.
They are spaced at 4 mb intervals. When there is no discernible air
mass there tends to be a no-man's-land between parcels of Lows and
Highs called a col.

I can't remember what pressures they tend to but it will be something
around 1005 to 1010 mb.
