Analysis of a 12-year record of sea-surface temperatures off Pt. Sur, California
L. C. Breaker
Daily observations of sea-surface temperature (SST) taken just north of Pt. Sur, California over the past 12 years are examined for statistical and oceanographic content. Spectral analysis of the data reveals an annual cycle and two harmonics, but no obvious influence from the local winds or tides. A statistical model has been constructed based on a decomposition of the data into its various deterministic and random components. As expected, the model provides forecasts which are significantly better than those that would be obtained from a simple climatological treatment of the data alone. The model is also used to generate simulated series, which in turn are used as a basis to estimate adequate sampling rates. In 6 years of the 12 year record, an abrupt major decrease in SST was observed between February and April and has been identified as the spring transition to coastal upwelling. One such transition was found to occur almost simultaneously at three locations; including Pt. Sur, along the California coast between Pt. Conception and San Francisco. The data also indicate that a well-defined annual temperature cycle does exist at Pt. Sur although its range is reduced and its maximum occurs later in the year than would normally be expected at this latitude. Three El Nino events are clearly evident in the 12-year record including the present El Nino; SSTs have increased by almost 3C at Pt. Sur as a result of the present El Nino warning. Over the whole 12 year period an average increase in temperature of 1.6 C was found.

A wetbulb temperature at hPa in a tropical atmosphere of − °C ( °F) is required to initiate convection if the water temperature is °C ( °F), and this temperature requirement increases or decreases proportionally by 1 °C in the sea surface temperature for each 1 °C change at hpa. story of seasonal sea surface temperature changes that, at 00 N W at least, seasonal changes in than a strictly dynamical response to the winds.

It is suggested that the 40–50 day oscillation in sea-surface temperature off central California may be related to the 40–50 day oscillation in the tropical troposphere through atmospheric teleconnections between the tropics and by: The Office of Satellite and Product Operations (OSPO) is part of the National Environmental Satellite Data and Information Service (NESDIS).

Sea surface temperature, much like the atmosphere’s temperature, is constantly changing. Water warms up and cools down at a slower rate than air, so diurnal variations (heating during the day and cooling during the night) seen in the atmosphere are hard to observe in the ocean.
An empirical orthogonal function analysis of an advanced very high resolution radiometer sea surface temperature data set encompassing the spring–summer period during – was used to examine patterns of temperature variability off northern and central California.

Sea surface temperature increased during the 20 th century and continues to rise. From throughtemperature rose at an average rate of °F per decade (see Figure 1). Sea surface temperature has been consistently higher during the past three decades than at any other time since reliable observations began in (see Figure 1).
