AIR MAIL

Where today’s air came from

The air arriving over California about 5,000 feet above the ground was over British Columbia three days ago, and over the Great Lakes a day ago, about 2,790 miles back along its path. It rose from near the ground on the way. Near the ground the air came from British Columbia; at 10,000 feet, from the open Pacific. Traced back 72 hours through NOAA’s hourly RAP analyses and the GFS beyond them, nine paths at each of three heights.

THIS WEEK, SIX YEARS AGO Nov. 12–13, 2020

The wettest two days this week has seen

5.96 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 4.55 inches, fell in 2009.

THE GROUND

What California stands on

California’s center stands about 120 ft above sea level. Within three miles the land runs from 0 ft to 180 ft, a difference of 180 ft: gently rolling country. Open water lies within three miles.

Under the town center the state geologic map shows Upland Deposits (Western Shore) (gravel, sand), from the Pleistocene, less than 2.6 million years old.

The section below crosses 4 rock units mapped at the surface.
