摘要
由测高卫星升、降弧段海面高交叉点约束方法,用TOPEX/POSEIDON测高数据计算了黄海、东海、南海海域的海平面变化;分析了三个海区海平面变化的相关性;在频域内讨论了它们之间的相干性;分析了海水面积随纬度带的变化对不同纬度分布的海区海平面变化量的影响。
Based on the constrained method of sea surface height at crossover of the ascending and desconding arcs of altimetry satellite,this paper counts out the sea level change in Huanghai,Donghai and Nanhai with TOPEX/POSEIDON altimeter data and does research on the relativity and the coherence among the three areas.Furthermore,the effect of the water area change in different latitude band upon the sea level change in different latitude is discussed.
