Predicting Weather By The Moon - Xavier University Libraries

Weather By The Moon
There is an additional polar wobble in which the
poles move around in a 22 year cycle, also caused by the
Moon’s gravitational pull, causing shifts in the position of
magnetic north. Then there are cycles within cycles, like
the monthly variation between the minimum
declinations(18deg) and the mid-points(23.5deg), which
sees the same progression of 49 months, 50, 53, 54 and
then 49 again; making a grander cycle of 4 x 18 years, or
72 years. This is inter-linked with the Precession of the
Poles, for a day is lost in 72 years if one is using a lunar
calendar. As the seasons would gradually slip behind unless
the calendar dates were corrected, vernal
equinox(March 22nd)was considered a possible tweaking
day. Observation of when the Sun rose exactly in the east
marked out Equinox Day, i.e. which day would be called
March 22nd. Once it was designated as March 1st, the beginning
of spring and the start of a new season. Calendric
changes have seen the actual date shift forward. To know
where due east was required marker stones, and these also
can be seen on ancient stone circle arrangements.
SUMMARY
The Moon moves in four main ways at once.
1) the Phase cycle, that everyone can see(New Moon/Full Moon)
2) the Perigee cycle, which can be noted with the aid of some measuring
device or official almanac.
3) the Monthly Declination cycle, which can be observed if you
watch for the very second the Moon rises each day and record how far
along it is from due east along the eastern horizon; and
4) the Maximum/Minimum Declination cycle that cannot be seen, in
which the declination itself changes in the manner of a roller-coaster over
18.613 years. What does all this mean for our weather?
