AIR MAIL

Where today’s air came from

The air arriving over North Valley Stream about 5,000 feet above the ground was over Ontario three days ago, and over the Great Lakes a day ago, about 1,430 miles back along its path. Most of the nine paths traced from around the city agree. It rose from near the ground on the way. Near the ground the air came from the Ohio Valley; at 10,000 feet, from British Columbia. 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 North Valley Stream stands on

North Valley Stream’s center stands about 50 ft above sea level. Within three miles the land runs from 10 ft to 100 ft, a difference of 90 ft: gently rolling country. The highest named summit within 15 miles is Harbor Hill, about 380 ft, 9 miles north-northeast.

Under the town center the state geologic map shows Monmouth Group, Matawan Group and Magothy Formation (clay, sand, gravel), from the Late Cretaceous, 66 to 100 million years old.
