| 摘 要： | 本文基于SWAN(Simulating Waves Nearshore)模式研究了2001～2016年石岛海浪有效波高的季节和年际变化特征,评估了不同区域风场对其贡献,并探讨了其与ENSO的关系。结果表明,石岛有效波高受黄海季风系统的影响呈现显著的季节变化:12月份最大, 6月份最小, 1%大波有效波高季节变化不显著。石岛有效波高年际变化信号显著,其与风速年际变化之间的关系存在季节性差异:石岛有效波高和石岛、黄海区域平均风速不同月份的年际异常分别在7、10月份相关性较高,而石岛1%大波有效波高和石岛、黄海区域平均1%大风风速不同月份的年际异常则在8月份左右相关性最高。不同区域风场对石岛有效波高场的影响也呈现了季节性差异:夏季,黄海南部区域风场对石岛海浪的贡献较大,而石岛风场的贡献较小;冬季,石岛风场的贡献较大。ENSO(El Ni?o-Southern Oscillation)事件会对石岛有效波高的年际变化产生一定的影响,但影响比较小。本研究旨在对石岛海浪在季节和年际尺度上的变化特征以及风场等影响因素进行研究,对该海域海浪场进行了详细的认识,对了解该海域海浪有重要意义。

| Abstract: | In this study, we investigate the seasonal and interannual variabilities of significant wave height (SWH) in Shidao (SD) and assess the contribution of wind to SWHs in different areas by using the Simulating Waves Nearshore wave model. The relationship between SWHs and El Niño-Southern Oscillation (ENSO) is further explored. The results are as follows:SWHs in SD are significantly affected by the monsoon system in the Yellow Sea (YS) and show seasonal variations, with SWHs reaching their maxima in December and minima in June. Meanwhile, 1% SWHs are not significant. The relationship between annual anomaly of SWHs and wind speed exhibits seasonal variations. Generally, the relationship is high in July and October, and their maxima appear in August for 1% SWHs and 1% wind speed. In winter, the wind in SD area has a considerable contribution to SWHs in SD. Meanwhile, in summer, the contribution of the wind from the southern part of SD is prominent. Furthermore, ENSO events have a slight influence on the interannual variations of SWHs in SD by affecting the wind in the YS. This research will be a useful reference for further research on SD wave. |
