Abstract

The temporal evolution of the global mean sea level (GMSL) is investigated in the present analysis using the monthly mean values obtained from two sources: a reconstructed dataset and a satellite altimeter dataset. To this end, we use two well-known techniques, detrended fluctuation analysis (DFA) and multifractal DFA (MF-DFA), to study the scaling properties of the time series considered. The main result is that power-law long-range correlations and multifractality apply to both data sets of the global mean sea level. In addition, the analysis revealed nearly identical scaling features for both the 134-year and the last 28-year GMSL-time series, possibly suggesting that the long-range correlations stem more from natural causes. This demonstrates that the relationship between climate change and sea-level anomalies needs more extensive research in the future due to the importance of their indirect processes for ecology and conservation.

全球海平面动态的影响

本分析利用从两个来源（重建数据集和卫星高度计数据集）获得的月平均值，对全球平均海平面（GMSL）的时间演变进行了研究。为此，我们使用了两种著名的技术，即去趋势波动分析（DFA）和多分形 DFA（MF-DFA），研究了所考虑的时间序列的缩放特性。主要结果是，幂律长程相关性和多分形适用于全球平均海平面的两个数据集。此外，分析还发现 134 年和最近 28 年全球平均海平面时间序列的缩放特征几乎相同，这可能表明长程相关性更多地是由自然原因引起的。这表明，气候变化与海平面异常之间的关系需要在未来进行更广泛的研究，因为其间接过程对生态学和保护具有重要意义。
