在在中国的边缘的海上的表面风中的长期的可变性与一个主导模式的单个价值分解方法被检验。interannual 和 interdecadal 模式被发现季节地并且空间地依赖,与重新分析并且产出高度一致的结果的卫星遥感数据。学习表明在华东海上的夏天季风风经历了在 1960 年代末变弱的 interdecadal 并且在 2005 开始了坚持的恢复。学习也显示出自从 1960 年代的由超过 2 m/s 的在南部的华南海的冬季季风的渐渐的变弱,与来自在波罗洲的沿海的气候车站的证实。这现象没在以前的季风研究被报导。
Long term variability in the surface winds over the marginal seas of China is examined with a dominant-mode singular value decomposition method. Both interannual and interdecadal patterns are found to be seasonally and spatially dependent, with reanalyses and satellite remote sensing data yielding highly consistent results. The study reveals that summer monsoon winds over the East China Sea experienced an interdecadal weakening in the late 1960s and began a persistent recovery in 2005. The study also shows gradual weakening of the winter monsoon in the southern South China Sea by more than 2 m/s since the 1960s, with corroboration from coastal climate stations in Borneo. This phenomenon has not been reported in previous monsoon studies.
