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. |

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. |

The December Solstice
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. |
