AIR MAIL

Where today’s air came from

The air arriving over Port Heiden about 5,000 feet above the ground was over a point about 15,870 miles to the east three days ago, and over the open Pacific a day ago, about 18,350 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 the Bering Sea; at 10,000 feet, from a point about 19,190 miles to the east. 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.
