AIR MAIL

Where today’s air came from

The air arriving over New Castle about 5,000 feet above the ground was over the North Atlantic three days ago, and over Ontario a day ago, about 1,390 miles back along its path. It rose from near the ground on the way. Near the ground the air came from the Maritimes; at 10,000 feet, from the Atlantic off Florida. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
