AIR MAIL

Where today’s air came from

The air arriving over Crab Orchard about 5,000 feet above the ground was over the open Pacific three days ago, and over the central Plains a day ago, about 3,300 miles back along its path. It came down from about 14,000 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; 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.
