I have just been made aware of this article which seems to suggest
something
I had suspected: that lunar tides are linked with jet streams. The
article
is entitled:

"Equatorial Ionospheric Electrodynamic Perturbations During Southern
Hemisphere Stratospheric Warming Events"

But the abstract says:

"We also compare these data with extensive recent
results that showed the fundamentally important role of lunar semidiurnal
tidal effects on low latitude electrodynamic perturbations during of
arctic
SSW events."

If SSWs are caused by waves in jet streams breaking, then there is some
sort
of connection with lunar tides.

Cheers, Alastair.

Why just lunar tides? the solar component of the tides are half as strong
as
lunar ones

The solar tides are masked by the effects of solar radiation with which they
coincide.

The Blocking Highs of the North Atlantic follow a seasonal cycle of 2
1/2, 3, 4 and 2 1/2 month intervals, with the peak in January and
August (IIRAoT.)

Also, IIRC, the peaks coincide with the movement of the ITCZ and the
North Atlantic hurricane season (though I forget why and how.)

The sequence of events on the sea level chart is a couter clockwise
rotation of a multiple Low system. This is followed by a large
magnitude earthquakes of a value comparable to the overall pressures
in the system, a tropical storm -similarly appointed and then the
block.

Highs in winter tend to be very high pressure and those in summer
almost flaccid. I have the impression that the summer stuff is due to
the lack of Polar air and the abundance of exrta tropical air.

The retrograde motion strikes me as having something in common with
the work of Astrology -bearing in mind that there was once no
difference in the term and the astronomy scholars regarded as cutting
edge scientists even today.

spitFor a given definition of the term scientist/spit

I have no idea how to cast an horological chart though if anyone here
could help I'd be grateful. (Unless you are Dawlish, that is. I rather
suspect the tit might In which case, I'd rather not know.)

The occurrence of SSWs in something approaching multidecadal
timescales has flummoxed research since the following ones are not
usually of the same or similar value.

This is likely to be due to the cause being a signicant event that
occurs only once in a while rather in the manner of a Saros cycle as
opposed to something as the incremantal steps seen with something such
as the solar declination (and lunar declination which is slightly more
complex but again, is of multistepped increments.)

What the other planets do to accomplish this I can't say. Apparently
it's the cobined resultant of the solar system that keeps the moon in
its place. (Which incidentally explains why the earth is still in its
present orbit and why the earth and moon have not moved off to pasture
new -not will they.)

I have the impression it must be the way they focus the solar winds
and earths "bow shock". But I point no fingo.
