【摘要】：利用福建沿海几个主要验潮站数据与法国空间局(CNES)AVISO多卫星融合资料分析了福建近海及其周边海域海平面的时、空变化特征及主要模态,并简要分析福建近海海平面变化趋势.得到如下结论:近54a(1960~2013年)福建沿海相对海平面上升约2 mm/a,福建沿海海平面变化存在显著的季节变化和2~3a及6~8a的年际变化特征,这与ENSO和长周期天文分潮的变化周期较为吻合;对比同期卫星高度计资料和潮位站资料(1993~2012年)发现,卫星高度计与潮位站分析结果基本一致;卫星高度计和潮位站分析结果表明,福建沿海区域海平面近20a平均线性变化趋势约为4 mm/a.
[Abstract]:The temporal and spatial variation characteristics and main modes of sea level in the coastal waters of Fujian are analyzed by using the data of several main tidal stations along the coast of Fujian and the AVISO multi-satellite data of CNESN. The trend of sea level change in Fujian coastal waters is briefly analyzed. The following conclusions are obtained: the relative sea level rise in the coastal area of Fujian is about 2 mm/a during the past 54 years from 1960 to 2013. There are significant seasonal variations and interannual variations of 2 ~ 3 and 6 ~ 8 years in the coastal sea level in Fujian Province, which are in good agreement with the ENSO and long-period astronomical tide variation periods. Comparing with the data of satellite altimeter and tidal station during the same period (1993-#date0#), it is found that the results of satellite altimeter are basically consistent with those of tidal station. The results of satellite altimeter and tidal station analysis show that the average linear variation trend of sea level in the coastal area of Fujian is about 4 mm / a in recent 20 years.
