AIR MAIL

Where today’s air came from

The air arriving over Poipu about 5,000 feet above the ground was over the Pacific south of Hawaii three days ago, about 1,010 miles back along its path. Near the ground the air came from the open Pacific; at 10,000 feet, from the Pacific north of Hawaii. 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.
