However powerful a tropical storm may be, the storm is only a small
part of the system.

As an whole, the convective currents on or in the oceans are in
themselves only a part of the thing. But even then these things
are mere covering, superficial.

I'd always thought there was a step between the three body problem and
any direct occurrences because of the sun and moon.

I wonder what other steps there are between the engineering miracle we
live on and its reactions to the other planet in our orbit.

"The Sun passes through 11-year activity cycles in few of which the
star failed to become active

According to predictions, since the beginning of 2009, many more
sunspots and solar flares should have been identified on its surface.
They say that the magnetic phenomenon called solar jet streams is
responsible for this delay in the Sun's response time.

These streams are generated at the poles of the star, and then travel
towards the Equator at a relatively low speed of ten kilometers per
hour. When their journeys take them to 22 degrees latitude North and
South, they mark the beginning of a new solar cycle. But exactly why
the cycle starts when the streams reach this precise latitude is still
unknown.

NSO researchers believe that the reason why the latest cycle of the
Sun was delayed is that the jet streams moved slower than usual. Those
generated in 1996 took 13 years to reach the 22-degree-latitude and to
trigger a new period of activity, rather than the regular 11 years."

Every morning a minute pressure difference follows the sun. Presumably

I don't know if it can be measured for all the other background
changes but early in the days of admiralty log books providing the
weather data that people like FitZroy tried to work with, a certain
mid Atlantic island governor studied the phenomenon and deduced such a
wave from statistical analysis.

I think he was the governor of St Kits and Nevis or whatever it was before they were franchised. Circa 1840? Anyone know for sure. (T'was a long time ago.)

A small step from that is looking at the Atlantic chart every 6 hours
and watching these small pressure waves build up. I don't pretend to
know their cause but you really can see Low pressure regions develop
as these things converge.

So that's how I did it. I often wondered.

This is what I mean when I use the term. I have no real idea what the
more knowledgeable understand about it. Nor do I care over-much.
Likewise when a series of waves (sound waves) reach a certain point
under the earth where they can meet and reinforce other sets of waves
arriving there from different directions, the peaks and troughs
produced have a frequency of their own.

Meaning contemporary doctrine and dogma about seismic waves is immaterial to the study of earthquakes.

Sometimes these are barely noticeable. Sometimes they peak as small
tremors, sometimes as larger ones and sometimes as catastrophic
earthquakes.

And the weather changes.

That bit still hold true and always will except that the catastrophe could be tornadic or in the presence of storms in the tropics and severe cold weather in North America and western Europe (as opposed to unusual snow fall anywhere) "extreme"~ish volcanic eruptions.

I hadn't appreciated the inverse relationships although teleconnections were obvious before I even knew of uk.sci.weather's existence or how to find weather charts... never mind the word teleconnection:

Permutations of these effects are tornadoes, volcanic eruptions and
above cloud lightning. Too little is known and almost nothing is
reported on the latter phenomenon to make conjugation with lunar
phases possible.

Since it IS possible to show a relationship between the other stuff
(one only has only to look for a series of the right lunar phases
running consecutively for that.) It is possible to work out what the
weather should be doing when it palpably is not doing what it should.

It doesn't take much experience to form the idea that a run of certain
weather should bring a devastating phenomenon. Since these usually
occur at the end of the run, the time to watch out for them is towards
the end of the last of the similar phases.

Although the present run, now ending has been a wet spell or series of
spells, the type of wet spells has differed one from the other. But we
should still be able to see something interesting as the next phase
takes hold on the earth.

The 29th of June 2009, should be an interesting distraction as it
breaks the spell temporarily:

29 JUNE 11:28 A spell of fine weather with ridges dominating part of
the spell.
7 JULY 09:21 An unstable thundery spell of the sort that didn't
produce much thunder IIRC from the 25th April.
15 JULY 09: 53 And this one is some 30 minutes different from the last
which is quite a near miss for lunar phases which are seldom that
obliging in producing matches.

I think even smallbrain should be able to follow that, and I don't
mean that in the way he usually runs up one's backside after every
post.
