The Earth's orbital path around the distant central star causes the
variations on the orbital shadow/solar radiation boundary against
fixed axial orientation.
With visible images of the Earth from space and the orbital dynamic/
orbital orientation changes as the cause for global climate and
hemispherical weather patterns( seasons),the pseudo-dynamic of
variable axial tilt can be disposed of as a climatological principle.
In the images above it is easy to see how the variations in
heliocentric latitude as the Earth move around the Sun alters the
shadow/solar radiation boundary across the poles,longitudinally the
rate of change of the boundary follows Keplerian geometry -

That orbital change plays a huge role in the noon Equation of Time
correction insofar as it contributes,almost solely,for the Total
vatiations in the length of the daily cycle.
Who is adventurous and curious enough to grasp and solve the
variations in the orbital shadow/solar radiation boundary.It is well
worth the effort and is begging an accuate explanation. |
