了解长期的海浪气候变化对评估气候变化对海岸和海洋物理和工程的影响是很重要的。在气候变化的背景下，波动相关型可以代表波动气候变率。本研究的目的是确定如何大规模的波高的空间分布变化每月的基础上，以及它们是如何影响各种遥相关模式使用再分析数据集。北太平洋和北大西洋东部的波高气候对遥相关型的响应比相应的西部更为敏感。通过经验正交函数分析，得到了冬季月平均波高变化的主要空间分布型。北太平洋和北大西洋的三种主要模式是相似的。值得注意的是，三个主导型之一，带状型，表现出很强的联系，在每个海洋的遥相关型。T...
AbstractUnderstanding long-term, ocean wave climate variability is important to assess climate change impacts on coastal and ocean physics and engineering. Teleconnection patterns can represent wave climate variability in the context of climate change. The objective of this study is to identify how large-scale spatial distributions of wave heights vary on a monthly basis and how they are influenced by various teleconnection patterns using reanalysis datasets. The wave height climate responses to teleconnection patterns in the eastern part of the North Pacific and North Atlantic are more sensible than in the corresponding western parts. The dominant spatial patterns of monthly averaged wave height variability in winter were obtained by empirical orthogonal function analysis. The three dominant patterns in the North Pacific and North Atlantic are similar. It is remarkable that one of the three dominant patterns, a band-shaped pattern, exhibits a strong relation to the teleconnection pattern in each ocean. T...
