基于夏威夷海平面研究中心提供的南极6个验潮站多年逐时潮位数据,本文首先利用迭代调和分析对初步观测数据进行补缺,并在此基础上计算月平均海平面,最后利用功率谱分析、最大熵谱分析、奇异谱分析等方法确定海平面的相对变化速率和振动周期。研究表明,南极海平面相对上升速率与全球其他区域基本一致(3mm/a-7mm/a),但是在个别测站(例如:Esperanza)的上升速度非常明显,达到厘米级。 Based on the multi-year hourly tidal level data of six tide gauge stations in Antarctica provided by the Hawaii Sea Level Research Center, this paper firstly compensates for the initial observation data by iterative harmonic analysis and then calculates the monthly average sea level. Based on the power spectrum analysis, Maximum entropy spectrum analysis, singular spectrum analysis and other methods to determine the relative rate of change of sea level and vibration period. Studies have shown that the relative rate of rise of Antarctic sea level is basically the same as that of the rest of the world (3mm / a-7mm / a), but the rate of ascent at individual stations (eg Esperanza) is very high at the centimeter level.
