AIR MAIL

Where today’s air came from

The air arriving over Sparta about 5,000 feet above the ground was over the Atlantic off Florida three days ago, and over New England a day ago, about 1,760 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It came down from about 9,400 feet up, warming and drying as it sank. Near the ground the air came from the Maritimes; at 10,000 feet, from the Atlantic off the Carolinas. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
