Default What causes the seasons

Traditionally,the seasons were explained using a vague reference to
'tilt' as though the orientation of the Earth to the Sun was
responsible for temperature fluctuations at different latitudes.

The actual cause of the seasons and a suitable explanation reflecting
the planetary dynamics behind these changes is quite different and
requires the isolation of daily and orbital characteristics.This is
achieved by focusing on the planet's two daylight/darkness cycles and
the individual cause of each insofar as we experience the daily
daylight/darkness cycle due to daily rotation and the entirely
separate polar daylight/darkness cycle where ,after a brief twilight
period at the orbital point of the equinoxes,6 months of darkness
turns into 6 months of daylight and visa versa.

The polar coordinates,where daily rotation is absent or residual,pass
through the circle of illumination at the equinoxes and these polar
coordinates act like a beacon for the orbital behavior of the Earth
insofar as aside from daily rotation,all locations on the planet would
experience a single daylight/darkness cycle as our planet,moving along
its orbital circumference turns through 360 degrees to the central Sun
over the course of an annual orbit.It takes a broom handle to
substitute for daily rotation and its orientation and any object to
act as the central Sun to imitate the orbital behavior of the Earth
by walking around/orbiting the central object/Sun.The broom
handle ,again,acting for 'tilt',only provides a window into the
orbital behavior of the Earth as a person must walk backwards in
circling the object,sometimes crabbing sideways before walking
forwards in completing a circuit.As a person will observe that
different parts of their body face the central object at different
points from an orbital line perpendicular to the central object/Sun,
like a separate longitudinal motion that runs from a line from Arctic
circle down to Antarctic circle rather than the traditional view of
referencing axial 'tilt' or inclination to the Sun.

In short,an additional piece of information is required to explain the
seasons or why natural noon cycles vary when allied with daily
rotation and the most suitable route is through acknowledging the
planet's two daylight/darkness cycle with the explanation for the
latter strictly an orbital characteristic.I do not have to remind
readers that the inability to explain the polar daylight/darkness
cycle is not that much more difficult than explaining the daily
daylight/darkness cycle due to daily rotation so people have now a
gauge as to how astronomically intuitive they are .

Once an astronomer sees the polar twilight sandwiched between polar
daylight and polar darkness in terms of the passage of the polar
coordinates through the circle of illumination they will be unable to
work with 'tilt' as the cause,the role of 'tilt' goes into determining
whether a planet has a largely equatorial climate like the Earth or a
polar climate such as Uranus which has unique axial orientation.

The hostility to basic experiences is something else to witness - the
Earth is round and rotating hence the daylight/darkness cycle.

Because rotation at the polar coordinates is absent or residual,the
explanation for the single polar daylight/darkness cycle must arise
from the Earth's orbital motion so that to explain what happens at the
equinoxes where the polar coordinate pass through the circle of
illumination creating a brief polar twilight dividing 6 months of
darkness or 6 months of daylight is strictly an orbital dynamic and
characteristic.

So,have you got his straight,the polar coordinates act as a beacon for
the orbital behavior of the Earth hence you get to explain the Earth's
two daylight/darkness cycles separately and unless you are utterly
dull,and you may very well be considering the addiction to 'sidereal
time' reasoning,you are seeing a new explanation for the seasons and
the variations in the natural noon cycles.

What can be said of the U.K. authority on the seasons and especially
at the equinoxes ! -

http://www.nmm.ac.uk/upload/img_200/...ht-equator.jpg

http://www.nmm.ac.uk/gcse-astronomy/...lace-in-space/

I have never seen anything quite like that webpage in all my
investigations into what went wrong due to a series of events in the
late 17th century which saw astronomy turned on its head in the
attempt to use the calendar based Ra/Dec framework as a bridge between
experimental sciences and celestial observations.At least those who
deserted this forum had just enough intelligence to realize that they
inherited an idea of planetary dynamics which is somewhere between a
flat Earth concept and intellectual oblivion and typified in that
Royal Observatory website.

To put the whole thing into an accurate perspective - there is a guy
running around the usenet who thinks he sees a human skull in coal and
then jumps to a conclusion that 'man is as old as coal',the
astronomical and distinctly English version is not that much more
subtle as an assumption and as a conclusion -

"... our clocks kept so good a correspondence with the Heavens that I
doubt it not but they would prove the revolutions of the Earth to be
isochronical..." Flamsteed

So Pete,when you link daily rotation directly with apparent stellar
circumpolar rotation through 360 degrees as Flamsteed here tried to
do ,you end up trying to explain the orbital motion of the Earth off
the same celestial sphere and same equatorial coordinates making this
the most joyless astronomical era possible.

The only sign that there are intelligent people out there is actually
the desertion of u.k.sci.astronomy but there is no sign of courage
from people who are really needed to face this enormous crisis head
on.Unless people wish to spend the rest of their lives or the next 40
years following a big,dumb mistake that Flamsteed made,they must stand
apart in an open challenge to the boring and the dull by actually
discussing what is correct as opposed to dealing with nonsense that
exists only in the imagination of mathematicians.
