Air and water circulation patterns of the bight off the Southern California coast up to Point Arguello. P-3750 gave the synoptic or macroscale justification of the bight-size flow offshore; this paper defines microscale patterns over a grid of ten-minute squares at three-hour intervals from 1300-1900 PST, for the most traveled area from Marina del Rey to Catalina. The eastern Pacific high accounts for 79 percent of the flow and the Catalina eddy for 30 percent; 15 percent reflects Santa Ana wind conditions. Land breezes influence the flow up to 10 n mi offshore, so the prime indicator of the flow pattern is the San Nicolas Island station. 25 pp. Ref.

The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
