AIR MAIL

Where today’s air came from

The air arriving over De Kalb about 5,000 feet above the ground was over the Maritimes three days ago, and over New England a day ago, about 790 miles back along its path. It came down from about 10,400 feet up, warming and drying as it sank. Near the ground the air came from Canada; at 10,000 feet, from the North Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
