AIR MAIL

Where today’s air came from

The air arriving over Carnot-Moon about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,180 miles back along its path. Near the ground the air came from the central Plains; at 10,000 feet, from the open Pacific. It feels dry all the same. 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 1933 Nov. 16, 1933

The coldest this week has been

9° on Nov. 16, 1933, the coldest reading for this week of the year since 1871. Next is 10° in 1986.

THE GROUND

What Carnot-Moon stands on

Carnot-Moon’s center stands about 1,130 ft above sea level. Within three miles the land runs from 680 ft to 1,230 ft, a difference of 550 ft: hilly country. The highest named summit within 15 miles is Big Knob, about 1,400 ft, 14 miles north.

Under the town center the state geologic map shows Casselman Formation (shale, clastic), from the Carboniferous, 299 to 324 million years old.

Where Carnot-Moon’s rain goes

A raindrop that lands in Carnot-Moon reaches the Gulf of America by way of Narrows Run, the Ohio and the Mississippi: about 1,930 river miles.
