1. PLOT DECLINATIONS FOR THE MONTH
The Moon moves around the earth once per month
on or about the Earth’s plane of orbit around the Sun. It
strays a degree a year from this plane, never going above
or below 5°, making for an 18.613-year cycle in all. Within
the month, it spends 14 days in one hemisphere and 14
days in the other, oscillating around the ecliptic. When it
is uppermost it is at the northern declination point, and
travelling parallel to the earth for 3 or 4 days. The weather
at this time will be slow-moving. Winds and anticyclones
will be dragged along latitude lines.
Then the Moon treks downward towards the southern
declination point. Dragged by the Moon as it crosses the
Equator either going northwards towards its northern declination
point or southwards towards the southern point at
this time weather patterns are often called fast-moving
weather systems. Winds at this time will generally be
northerly(from NE or NW) or southerly(from SE or SW).
How do you find out when the declinations occur?
This information is available from many astrological books
and prorammes, or sometimes from your local newspaper.
Another way is to obtain a publication put out every 10
