AIR MAIL

Where today’s air came from

The air arriving over Tolsona about 5,000 feet above the ground was over a point about 860 miles to the northwest three days ago, and over interior Alaska a day ago, about 970 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 12,700 feet up, warming and drying as it sank. Near the ground the air came from interior Alaska; at 10,000 feet, from a point about 8,520 miles to the east. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
