AIR MAIL

Where today’s air came from

The air arriving over Windsor about 5,000 feet above the ground was over British Columbia three days ago, about 2,420 miles back along its path. It came down from about 15,600 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the northern Rockies. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
