There are many scientists who believe that surface inclination to
solar radiation in the main input into temperature fluctuations
between July and January due to the fact that the dominant conceptions
still retain rotational inclination to the Sun whereas the main input
is the length of time a given latitudinal location spends in solar
radiation of the orbital shadow of the Earth,the Equator sees the
least variation while polar latitudes see the greater temperature
asymmetries allowing for micro-variations in some parts of the planet
due to proximity to oceans and things like that.

It is because of the utter hostility towards the planet's daily
rotational and orbital characteristics by followers of Royal Society
empiricism that the Equatorial La Nina event is not considered in
dynamical terms as the variations in water temperatures between a hot
El Nino and cold La Nina influence temperatures and subsequently
weather patterns depending on which event exists at the Equator.

The point is that without the major inputs from global climate into
hemispherical weather patterns which arise from equatorial and
therefore rotational dynamics,climate will just not make sense.The
Earth turns 1037.5 miles per hour and a full 24 901 miles in 24
hours,as daily rotation is separate to orbital motion,the yearly
fractional difference is omitted and retained by the orbital
characteristic of the Earth hence never more than a full 365 rotations
in an annual circuit.This allows genuine investigators to revisit both
planetary dynamics and solar inputs anew for climate inputs but that
is only possible when the conceptual baseline of the seasons are
explained accurately through planetary dynamics.
