AIR MAIL

Where today’s air came from

The air arriving over Ruby about 5,000 feet above the ground was over a point about 400 miles to the south three days ago, and over the Gulf of Alaska a day ago, about 590 miles back along its path. It came down from about 10,300 feet up, warming and drying as it sank. Near the ground the air came from Canada; at 10,000 feet, from a point about 7,820 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.
