We have microwave images but they are hard to interpret. The north wind and near freezing temperatures of the last week have brought with them gray overcast and almost continuous snow. A low pressure centered on the ice cap to the southwest of us seems to be the cause of this weather and the reason clouds have obscured visual satellite images. It is strange for me, a northern hemisphere weather watcher, to think of a warm north wind. In Maine, north winds mean clear cool air.
Southerly winds produce that effect here.
Night and day, the temperature for the last few days has been just below freezing, within a degree or so, and remarkably constant. The change in the day length here is remarkable. I arrived at McMurdo station just about one month ago. At that time the sun was above the horizon twenty-four hours a day, and would not dip below until February 18. A week from now will be the equinox, when worldwide there will be twelve hours of light and twelve hours of darkness.
