Default The December Solstice

As with daily rotation,somewhere it is orbital midday and somewhere
else orbital midnight as the planet moves along it orbital
circumference and turns slowly and unevenly to the central Sun with
the orbital daylight/darkness cycle coincident with the orbital period
of the planet.In a few days,the polar coordinates will turn to their
respective positions of orbital midday (South pole) and orbital
midnight (North poles) where these points exist at a maximum distance
from the circle of illumination as they turn in a circle to the
central Sun.

The hemispherical terms of winter/summer solstice tends to obscure the
orbital noon/midnight terms insofar as at the poles where 6 months of
daylight follows 6 months of darkness puts the orbital cycle into
correct perspective,at least for those who now know it requires an
additional orbital component to explain the seasons.

Is there the slightest point in asking you to explain what you mean
here?

People now repeat it back to me as though it were trivia,in the
absence of daily rotation every location on the planet would
experience a single daylight/darkness cycle due to the orbital motion
of the Earth,the polar coordinates therefore act like a beacon for
this orbital component by way of 6 months of daylight followed by 6
months of darkness.

In terms of the orbital turning of the polar coordinates through 360
degrees hence the orbital cycle,the axis of this turning passes
through the center of the Earth from Arctic to Antarctic circles,the
distance covered by the polar coordinates and all other orbital points
on the planet as it turns to the central Sun over the course of a year
is the Arctic/Antarctic circle circumference divided by 365.24 days
or roughly 30 miles per day.The polar coordinate will therefore turn
roughly 120 miles to bring those points to a maximum distance to the
circle of illumination which is rightfully called the December
Solstice where the polar coordinates exist at orbital noon and orbital
midnight.

There is nothing remotely dour about this and it should not attract
the usual nuisances,it is as much an astronomical gift as those from
the astrographers and should be appreciated as such.

The remaining 4 days will see the polar coordinates turn through
roughly 120 miles as they reach a peak distance from the circle of
illumination.An imaginary circle,like an orbital longitude line,
running around the Earth through North/South poles puts these
coordinates at orbital noon and midnight at the Solstice while it
takes only an imitation analogy to put the orbital componet in
perspective of the orbital motion of the planet.

There is nothing dour about this,if people can't enjoy the different
perspective then just leave it be or provide their own explanation as
to what happens to bring the December Solstice about.

To know the difference between a hemispherical terms of summer
solstice from a global terms such as the December solstice is to make
huge inroads into distinguishing weather from climate.The last few
weeks have seen exposure to the lack of definition and the
fault,albeit temporary,exists with astronomers who are unable to deal
with the necessary adjustment to split hemispherical weather from the
astronomical inputs.Far from being trivial,the distinction between
orbital midnight,mid-winter and the hemispherical lag which influences
the continental American idea of the beginning of meteorological
winter has an important and enjoyable dynamic to it,there is no
objection to the civil aspect of 3 months of winter conditions that
end around the equinox but the astronomical inputs which focus
attention on planetary dynamics are far more precise and easier to
deal with than local inputs of oceans and continents.

The Earth has a largely equatorial climate due the relationship
between the Earth's two main axes and the changing relationship as
they are referenced to the central Sun.In a day,the orbital
axis,stretching from Arctic to Antarctic circle through the center of
the Earth will align with the polar coordinates of daily rotation
directly opposite the central Sun,at least taken from a polar view,It
is,in fact,a way to consider an orbital longitude meridian that acts
separately to daily rotation and its motion and orientation as the
single daylight/darkness cycle of the planet arising from the
characteristics of the orbital motion is freed from the tendency to
reference the seasons using only right ascension and rotational
coordinates.

It would be nice,in an era occupied by very tenuous distinctions
between weather and climate,to consider the more accurate term of
December solstice from hemispherical terms of summer/winter solstices
as the former term allows for orbital noon and midnight along an
orbital longitude meridian circling the planet with the North/South
poles existing on that orbital line and 23 1/2 degrees off the orbital
axis.
