AIR MAIL
Where today’s air came from
The air arriving over East Hampton about 5,000 feet above the ground was over the Atlantic off the Carolinas three days ago, and over New England a day ago, about 1,220 miles back along its path. It rose from near the ground on the way. Near the ground the air came from Canada; at 10,000 feet, from the Atlantic off the Carolinas. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
