AIR MAIL
Where today’s air came from
The air arriving over South Huntingdon about 5,000 feet above the ground was over the western Atlantic three days ago, and over the Great Lakes a day ago, about 1,240 miles back along its path. Most of the nine paths traced from around the city agree. It rose from near the ground on the way. Near the ground the air came from the western Atlantic; at 10,000 feet, from Quebec. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
