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 New England a day ago, about 1,280 miles back along its path. Near the ground the air came from Quebec; at 10,000 feet, from the western Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
