AIR MAIL

Where today’s air came from

The air arriving over Iliamna about 5,000 feet above the ground was over the Bering Sea three days ago, about 410 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It came down from about 9,100 feet up, warming and drying as it sank. Near the ground the air came from a point about 180 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.
