AIR MAIL

Where today’s air came from

The air arriving over Tanaina about 5,000 feet above the ground was over a point about 280 miles to the southwest three days ago, and over the Gulf of Alaska a day ago, about 450 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 9,800 feet up, warming and drying as it sank. Near the ground the air came from the Gulf of Alaska; at 10,000 feet, from a point about 8,250 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.
