AIR MAIL

Where today’s air came from

The air arriving over Hickory Hills about 5,000 feet above the ground was over the Gulf of Alaska three days ago, and over the northern Plains a day ago, about 2,980 miles back along its path. It came down from about 13,300 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Canadian Prairies. It feels dry all the same. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
