AIR MAIL

Where today’s air came from

The air arriving over Waipio Acres about 5,000 feet above the ground was over the Pacific south of Hawaii three days ago, about 1,120 miles back along its path. It rose from near the ground on the way. 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.
