AIR MAIL

Where today’s air came from

The air arriving over Portage Lake about 5,000 feet above the ground was over the western Atlantic three days ago, about 1,160 miles back along its path. It rose from near the ground on the way. Near the ground the air came from a point about 340 miles to the northeast; at 10,000 feet, from the Mid-Atlantic. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
