AIR MAIL

Where today’s air came from

The air arriving over Tilton about 5,000 feet above the ground was over British Columbia three days ago, and over the central Plains a day ago, about 2,530 miles back along its path. It came down from about 16,800 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. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
