AIR MAIL

Where today’s air came from

The air arriving over Plymouth about 5,000 feet above the ground was over the Atlantic off the Carolinas three days ago, and over the western Atlantic a day ago, about 1,200 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. Near the ground the air came from Canada; at 10,000 feet, from New England. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
