Predicting Weather By The Moon - Xavier University Libraries

Declination
But if the Moon is not at either the northern or southern
declination points, but is crossing the equator, it drags
anticyclones with it in the same direction. So if the anticyclone
is north of us and the Moon is travelling between
north and south, the anticyclone will be pulled by the Moon
down across the country on a diagonal across the latitude
lines. On the weather map this will be southwest up to northeast
when the Moon is travelling to its northern point and
northwest to southeast when the Moon is travelling towards
the southern declination point.
More frequent and slower moving anticyclones, especially
over the South Island of NZ, leads to brief periods
of cold southerlies and in winter it leads to increased frostiness.
Whether or not anticyclonic or cyclonic systems are
generated depends on which way the moon is going. If coming
up from the south, the airflow causes anticyclones to
be formed to the left and cyclonics to the right. The
cyclonics are short-lived, because they are already well to
the east. Anticyclones will then typically move over the
country. You will get this happening around almost every
southern declination. Southern declinations are usually accompanied,
in winter, by full moons. Colder weather more
often applies around full moons, when the skies are clear
overnight and heat gets lost from the day.
In the opposite hemisphere, if coming down from the
northern dec, the SE airflow would still cause anticyclones
to be formed to the left (as viewed from space)and
cyclonics to the right. The northern hemisphere would typically
get this happening around a northern declination.
Northern declinations in the northern hemisphere are usu-
