January 22 2015, photo with moon, had clear air very similar to Dec 25, 2014. December 25 sun elevation was -13.12 degrees, while January -13.09 degrees, but had twilight brightness well below December 25 2014 Santa storm shine despite somewhat similar mega scale weather.
ECMWF map describes a pressure ridge from the Arctic Ocean and a minor Low pressure system over the Northwest Territories at pressures 30 mb higher than Santa Cyclone once over Central Quebec. It was cold over Cornwallis Island -38 C, while Yellowknife -19 C very Balmy 7 degrees above normal. The Ray Path towards under the horizon the sun had key ingredients for a bright light energy event:
Ray path in black, meant twilight had near ideal temperature contrasts to generate more light for those living in darkness 24 hours a day. But this low had lesser energy stored in it than during Santa storm. The proof was in the twilight. This latest observation continues proving even more the great capacity in judging how strong a cyclone might be when juxtaposed to a dark zone. With better equipment the same thing can be done with hurricanes or any high energy storm system. WD Jan 22, 2015
