SHORT-TERM SEA-LEVEL ANOMALIES AT MONTEREY, CALIFORNIA.
Abstract
A method was devised by which short-term deviations from the astronomical tides at Monterey, California were detected and measured in the absence of the predicted tides at Monterey. This was accomplished by comparing the observed tides at Monterey with the predicted tides at San Francisco. The sealevel deviations, or anomalies, that can be found using this method range in duration from several hours to two or three days. The sea-level variations that were detected during a six-month period at Monterey had magnitudes ranging between +0.9 and -0.8 of a foot and durations ranging from 3.5 to 39.5 hours. The largest anomalies found are attributed to sea breezes that were unaccompanied by any appreciable atmospheric pressure variations. On the other hand, pressure changes accompanying frontal passages appear to be the dominant cause of other anomalies in spite of wind effects. Time lags in the response of sea level to weather phenomena were as long as three hours. (Author)
