AIR MAIL

Where today’s air came from

The air arriving over North Merritt Island about 5,000 feet above the ground was over the Atlantic off the Carolinas three days ago, and over the Atlantic off Florida a day ago, about 450 miles back along its path. The nine paths traced from around the city fan out, so treat that as a best guess. It rose from near the ground on the way. Near the ground the air came from the Atlantic off the Carolinas; at 10,000 feet, from a point about 810 miles to the northeast. Air off the water carries moisture, which is why it feels humid. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THIS WEEK IN 1994 Nov. 15–16, 1994

The wettest two days this week has seen

8.04 inches of rain fell in two days, the most for this week of the year since records began in 1901. The next wettest, 4.67 inches, fell in 2001.
