AIR MAIL

Where today’s air came from

The air arriving over Key Colony Beach about 5,000 feet above the ground was over the Caribbean three days ago, about 520 miles back along its path. Near the ground the air came from the Caribbean; at 10,000 feet, from the Atlantic off Florida. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.
