中国大陆境内的O1分波应变负荷潮

根据Schwideiski海潮图,本文根据作者提出的积分Green函数方法计算了全球海潮O_1分波在中国大陆产生的应变负荷潮,并绘制了应变负荷潮在中国大陆的分布图。分布图表明,中国大陆全境的O_1分波应变负荷潮受太平洋海潮的控制,在中国南部沿海地区南海海潮的作用非常显著,此处应变负荷潮的振幅可以接近甚至超过固体潮的振幅,即使在大陆西部内陆地区,负荷潮的振幅亦可达固体潮振幅的百分之几。要合理解释应变固体潮的观测结果,正确考虑负荷潮的影响是十分必要的。

The O_1 Strain Load Tides in the China Continent

According to the cotidal charts of Schwiderski,the O1 wave strain load tides in the China continent have been calculated on the basis of the integrated Green's function proposed by the authors and maps of distribution of these load tides have also been constructed. The maps show that the load tides in the whole continent are controlled by the ocean tides in the Pacific Ocean, the influences of the South China Sea in the southern part of China are predominant where the load tide amplitudes can be equal to or even larger than those of strain earth tides, even in the west innercon-tinent of China the load tide amplitudes can reach several percents of earth strain tides. It is necessary to consider correctly the load tides in order to interpret the observed strain tides reasonably.
