| 摘 要： | 基于多种卫星测高资料融合海面高数据对黄海、东海、南海和全球海平面异常在1993年至2005年期间的变化趋势进行分析,结果表明:黄海、东海、南海线性趋势分别为5.05mm/a,4.8mm/a,4.27mm/a,均大于全球平均趋势项2.66mm/a,各海域的周期振幅和相位变化也存在较大差异。近海各海域与全球的海平面异常的小波交叉谱和相关谱分析表明,近海各海域与全球海平面异常变化在年际周期上具有较高的谱能,但相位差异较大,短周期相关性不明显。

| Abstract: | sea level anomaly data,spanning from 1993 to 2005,in the China Seas(the Yellow Sea,the East-China Sea and the South-China Sea) and in global area derived from multi-satellite altimetry missions is used to deduce the linear trends.The results shows that the trends of the Yellow Sea,the East-China Sea and the South-China Sea are 5.05mm/a,4.8mm/a,4.27mm/a respectively,these values are larger than that of the global(2.66mm/a).The cross-wavelet spectrum and wavelet coherency analysis of the sea level anomaly in the China Seas and in global area show that the strongest common power exist at annual periods,while the phases are different greatly,the coherency of short periods is unobvious. |
