OCEAN TEMPEKATUEES

Assuming this upward flow to be the only cause of the temperature 

 reduction, the theory developed on pages 372-374 will now be applied 

 to the series of temperature observations made off the Coronado Island 

 about twenty miles from San Diego (McEwen, 1916, pp. 267, 268 and 

 pi. 26). It follows from Ekman's theory (p. 401) that the vertical 

 velocity off the California coast is proportional to the component of 

 the wind velocity parallel to the coast, and decreases in magnitude as 

 the distance from the coast increases. For this reason the velocity 

 estimated from the temperature data mentioned above will be less 

 than that nearer the coast.
