I have been looking at Lunar Declinational periodicities and have found a natural analog weather forecast, that runs better than the models. I first looked at 27.32 day declinational cycles and filtered data by 27.32 day periods, and got a 5:1 signal to noise ratio.

Upon looking further at satellite photos, I saw that the Rossby wave patterns, generated by the lunar declinational tidal perturbations, as meridial flow surges, was a four fold pattern . I should have been looking at 27.32 X 4 = 109.28 day long patterns, so I redid the data, and got signal to noise ratios closer to 14:1 in temperature data sets.

The 18.6 year Mn cycle of ~6793.65 days holds the declination angle the
same but is the .6 year off of seasonal, so does not work, the 19 year Metonic cycle, skews the declinational angle over two or three cycles off of a good match. But it seems that one (27.32 day) declinational cycle short of a saris Solar /Lunar eclipse cycle yields, a period of ~6558 days which is 240 X 27.325 days. This conserves the four fold Rossby periodicity, holds the declinational angle close, and also almost synchronizes the planetary returns of the inner planets, to similar positions relative to the star field.

The forecast generated on the above website, reflects the natural cyclic patterns, of the lunar declinational tides returning in phase three cycle in a row, with the temperatures averaged together, for highs and lows for each day, and all forms of precipitation display as a composite of all three cycles.

The dates applied to the finished maps is for this, "the fourth cycle".
To have these maps follow the actual weather as well as they do, speaks to me as proof of the existence of a real cyclic pattern, of a real effect, of the Lunar declinational tidal forces at work.

The problems with this forecast method is the interference of the outer gas giant planets, via inductive effects of the solar wind streams of condensed concentration of ions following the increased magnetic flux of the solar magnetic fields that couple though each of / and all of the planets in relative strength to their "magnetic conductivity" not just their weak residual local global permanent magnetic fields.

At times of a Heliocentric conjunction of Earth, with one or more outer planets, that surge in solar wind strength and density (about 30 degrees wide)has secondary induction effects in the homo polar generator effects felt on the Earth standing electro magnetic charges, and by the rules of induction, increases the poles (-) to equator (+) charge gradient, and drives warm moist tropical air masses off of the ITCZ into the mid latitudes. For the first 12 to 15 days, then the effect reverses, and
the gradient reduces to the nominal, driving large polar air masses, toward the same mid latitudes.

When the Lunar declination mid summer and winter is close to the ~23 degrees of the solar apparent declination the atmospheric tidal bulges combine and move in phase, as the syzygy of the two are much stronger, greatly increasing the meridial flow, to even sometimes across the ITCZ, hence the pressure wave difference. The variations caused from out of phase heliocentric conjunctions with Earth, by the gas giant planets causes the compound signal seen in the data, viewing only the pressure oscillation.

This pattern I am using compensates for the El Nino cycles as it is part and parcel of the pattern. The Morning Glory waves in Australia, are an annual effect that peaks at syzygy by the same combination of atmospheric tidal components, meeting no topographical resistance clear across the Indian ocean.

The spring tornado outbreaks in the USA are created, and defined by the eddy on the Lee of the Rockies, by deflection of the westerly winds, as the Lunar tidal effects, primary waves as the tropical air masses are perturbed Northward as the Lunar declination goes to Maximum North, and drags tropical moisture with residual positive ionic charges on it. Generating outbreaks of tornadoes, when the wrap around of the northern air mass combines to form the other half of the tidal bulge.

This springs outbreak of 80+ (after ground team review the count now is 43) tornadoes was due to the increased effect, of the Heliocentric conjunction of Saturn with Earth, (February 23rd 2008) causing a greater than usual surge in the ionic / static charge gradient, intensifying the effects. As the same type of atmospheric tidal effects happened at Maximum South Lunar declination, with a (normally smoother mixing) in a secondary tidal bulge.

The moon was at maximum North declination of the 8th of May 2008, the tidal bulge that it produced brought tornadoes into the mid west, and now into the Southeast this is typical of a three day surge in severe weather, at maximum North lunar declination and at Maximum South declination they are produced starting a day later, from the day of to four days after culmination.

The forecast it generates is fairly stable but there are pulses of interference injected into it by the outer gas giant planets. The most recent heliocentric conjunction / transit of Saturn's solar wind stream, caused a surge of warmth and moisture to enter the South Eastern US, that is now 03-04-2008 being squeezed out in a spat of
severe weather, before the pattern returns to running with out outer planet interference until the heliocentric conjunction with Jupiter, on 07-09-2008.

The pattern is quite usable as a forecast, feel free to look at it and give any feed back you have.
