AIR MAIL

Where today’s air came from

The air arriving over Port Alsworth about 5,000 feet above the ground was over the Bering Sea three days ago, about 760 miles back along its path. It came down from about 13,800 feet up, warming and drying as it sank. Near the ground the air came from a point about 140 miles to the northwest; at 10,000 feet, from the Bering Sea. 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.
