An autocorrelation analysis of six temperature records from the North 

 Pacific and North Atlantic up to 40 years in length showed the existence of an 

 oscillatory function with period 1 year for all the stations studied, and of 

 another oscillatory function with period 0. 5 year for most of the stations. A 

 regression model containing annual and semiannual oscillatory terms was 

 found to provide a good statistical fit to the observed daily temperatures. 

 No long-term trends were detected in the sequences of annual mean temperatures, 

 but there were significant differences among these temperatures.
