AIR MAIL

Where today’s air came from

The air arriving over Belleville about 5,000 feet above the ground was over the open Pacific three days ago, about 3,020 miles back along its path. It came down from about 15,200 feet up, warming and drying as it sank. Near the ground the air came from the Canadian Prairies; at 10,000 feet, from the northern Rockies. 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.

THE GROUND

What Belleville stands on

Belleville’s center stands about 500 ft above sea level. Within three miles the land runs from 460 ft to 590 ft, a difference of 130 ft: gently rolling country. The highest named summit within 15 miles is Clarks Mound, about 670 ft, 6 miles northwest.

Under the town center the state geologic map shows Shelburn-Patoka Formations undivided (shale, limestone), from the Late Pennsylvanian, 304 to 307 million years old.
