Abstract
The data used are of air and sea-surface temperatures observed every three hours at the Ocean Weather Stations “ Extra ” (39°N,153°E) and “ Tango ” (29°N,135°E). Average diurnal variations of air and sea-surface temperatures are examined for every month of the year. It is noticed that the diurnal variation of air tempeature at both stations presents a characteristic curve with a swelling in the forenoon. Seasonal changes are examined of characteristic parameters of diurnal variations, e. g. the range, the time of occurrence of extreme values, the time of occurrence of the values equal to the diurnal mean, etc. Diurnal variation of the temperature difference between the air and the sea surface is shown at the end.
