AIR MAIL

Where today’s air came from

The air arriving over Belfast about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,690 miles back along its path. It came down from about 9,400 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

The hottest this week has been

75° on Nov. 16, 1993, the hottest reading for this week of the year since 1893. Next is 74° in 1902.

THE GROUND

What Belfast stands on

Belfast’s center stands about 580 ft above sea level. Within three miles the land runs from 340 ft to 720 ft, a difference of 380 ft: rolling country. The highest named summit within 15 miles is Kittatinny Mountain, about 1,540 ft, 12 miles north-northeast.

Under the town center the state geologic map shows Martinsburg Formation (shale, slate), from the Ordovician, 445 to 487 million years old.
