基于卫星测高资料研究全球海平面变化趋势

摘要

利用全球平均海平面的高程数据,研究基于反距离权重内插方法来处理Jason测高数据资料得出全球平均海面的数学模型,并将所得结果与利用WHU2013 MSS模型得出的结果进行了对比.此外,还通过计算全球海平面的变化值,分析了全球海平面变化的季节性特征、长期性趋势以及年际变化与厄尔尼诺事件的相关性.%To calculate and study global sea level height in processing altimetry data through the Jason-1 satellite,inverse distance weighted interpolation method is researched,and the results is compared with the WHU2013 MSS model.Then the global mean sea level is determined and used to analysis global sea level long-period trend,seasonal change and the correlation with El Nino.
