AIR MAIL

Where today’s air came from

The air arriving over Ciales about 5,000 feet above the ground was over the tropical Atlantic three days ago, and over the Caribbean a day ago, about 800 miles back along its path. 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.

THIS WEEK IN 1983 Nov. 14, 1983

98° on Nov. 14, 1983, the hottest reading for this week of the year since 1900. Next is 95° in 1905.
