AIR MAIL

Where today’s air came from

The air arriving over Nantucket about 5,000 feet above the ground was over the western Atlantic three days ago, and over New England a day ago, about 2,010 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It rose from near the ground on the way. Near the ground the air came from a point about 640 miles to the northeast; at 10,000 feet, from the North Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
