全球Schwiderski海潮模型M_2分波在中国大陆产生的应变负荷潮

DISTRIBUTIONS OF THE STRAIN LOAD TIDES IN CHINA CONTINENT CAUSED BY THE OCEANIC TIDE M_2 OF GLOBAL SCHWIDERSKI MODEL

本文利用计算应变负荷潮的积分Green函数方法,计算了全球Schwiderski海潮模型M_2分波在中国大陆产生的应变负荷潮.根据负荷潮的分布特点,中国大陆大致可以分成以东经100°为界的东、西两个区域.在东区,负荷潮主要受太平洋海潮的控制;在西部内陆地区,除太平洋海潮外,它们还明显地受印度洋海潮的影响.根据本文计算结果绘制的M_2分波应变负荷潮在中国大陆的地理分布图,为如何正确考虑M_2分波负荷潮对应变固体潮观测结果的影响提供了重要的参考资料.

The strain load tides in China continent caused by the oceanic Ma tide of global Schwi-derski model have been calculated in this paper by the method of integrated Green's function for the calculation of the strain load tides. According to the characteristic features of their amplitudes and phase lags, the strain load tides in China continent can be divided into east and west two zones approximately along the longitude line λ= 100°. In the east zone, the strain load tides are mainly controlled by the tides in the Pacific Ocean, in the west zone, except the Pacific Ocean, they are strongly influenced by the tides in the Indian Ocean. The calculated results and the charts of the geographycal distributions of M2 strain load tides based on these results provide an important reference data for considering the influence of the load tides on the observed strain tides.
