AIR MAIL

Where today’s air came from

The air arriving over August about 5,000 feet above the ground was over the California coast three days ago, about 630 miles back along its path. Most of the nine paths traced from around the city agree. Near the ground the air came from the Pacific off California; at 10,000 feet, from the Great Basin. It has stayed over land, which is why it feels dry. Traced back 72 hours through NOAA’s hourly RAP analyses, nine paths at each of three heights.

THE GROUND

What August stands on

August’s center stands about 20 ft above sea level. Within three miles the land runs from 10 ft to 50 ft, a difference of 40 ft: nearly flat ground.

Under the town center the state geologic map shows Quaternary alluvium and marine deposits (coarse-detrital), from the Pleistocene to Holocene, less than 2.6 million years old.
