AIR MAIL

Where today’s air came from

The air arriving over Lisbon about 5,000 feet above the ground was over the North Atlantic three days ago, and over the western Atlantic a day ago, about 1,260 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 the Mid-Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
