AIR MAIL

Where today’s air came from

The air arriving over Greenville about 5,000 feet above the ground was over the open Pacific three days ago, and over the northern Plains a day ago, about 3,170 miles back along its path. It came down from about 12,200 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Pacific north of Hawaii. 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, SEVEN YEARS AGO Nov. 13, 2019

The coldest this week has been

0° on Nov. 13, 2019, the coldest reading for this week of the year since 1893. Next is 5° in 1959.

THE GROUND

What Greenville stands on

Greenville’s center stands about 1,050 ft above sea level. Within three miles the land runs from 1,000 ft to 1,100 ft, a difference of 100 ft: gently rolling country. The highest named summit within 15 miles is Hoosier Hill, about 1,320 ft, 14 miles west-southwest.

Under the town center the state geologic map shows Lockport Dolomite (dolostone), from the Silurian, 425 to 445 million years old.
