AIR MAIL

Where today’s air came from

The air arriving over Greene about 5,000 feet above the ground was over Canada three days ago, and over the northern Plains a day ago, about 2,390 miles back along its path. It came down from about 11,200 feet up, warming and drying as it sank. Near the ground the air came from British Columbia; at 10,000 feet, from the Gulf of Alaska. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THE GROUND

What Greene stands on

Greene’s center stands about 1,180 ft above sea level. Within three miles the land runs from 980 ft to 1,340 ft, a difference of 360 ft: rolling country. The highest named summit within 15 miles is Wheeler Hill, about 1,410 ft, 8 miles southeast.

Under the town center the state geologic map shows Cuyahoga Group (siltstone, shale), from the Carboniferous, 324 to 359 million years old.

The section below crosses 7 rock units mapped at the surface.
