月平均海面以年周期振动为主，其次是半年周期。
The seasonal sea level change is of annual period and the second oscillation is of semi-annual period.
对多年的月平均海面温度进行调和分析，从而确定了一年和半年周期温度变化的振幅和相位。
The monthly mean sea surface temperature for many years are subjected to a harmonic analysis so as to determine the amplitude and phase of the annual and semi-annual temperature variations.
