摘要:

利用2010—2019年欧洲中期天气预报中心大气和海洋全球再分析数据提供的风场和海浪场数据, 对大连近海客运航线海域的海表面10m风速、混合浪有效波高、平均周期进行统计, 分析各海浪要素的多年平均、季节、月际变化及涌浪指数。结果表明: 大连近海的混合浪有效波高受海表风场影响显著; 各海浪要素存在明显的季节变化特征, 混合浪有效波高及海表面10m风速均为冬季最大、夏季最小, 而混合浪平均周期的最大、最小值均出现在夏季; 大连近海各海域春夏季的混合浪以涌浪为主; 受冷空气影响, 冬季各海域及秋季的渤海北部, 混合浪以风浪为主。大连近海风浪受海表风场扰动明显, 涌浪则主要受地形作用影响。

关键词: 再分析数据, 有效波高, 风浪, 涌浪指数

Abstract:

Based on the wind and wave field data provided by the Global Atmospheric and oceanic reanalysis data of the European Center for Medium-Range Weather Prediction (ECMWF) from 2010 to 2019, the 10 m wind speed, effective wave height of mixed waves and average period of the sea area of Dalian offshore passenger transport routes were statistically analyzed.The multi-year average, seasonal, and inter-monthly variations of each wave element and surge index were analyzed.The results show that the effective wave height of the mixed waves is significantly affected by the surface wind field.The wave elements have obvious seasonal variation characteristics.The effective wave height of the mixed waves and the 10 m wind speed on the sea surface are the maximum in winter and the minimum in summer, while the maximum and minimum of the average period of the mixed waves are in summer.The mixed waves in spring and summer are mainly swell waves.Under the influence of cold air, the mixed waves are mainly wind waves in the sea areas in winter and the northern Bohai Sea in autumn.The offshore wind waves in Dalian are affected by the surface wind field, while the surge waves are mainly affected by the topography.

Key words: Reanalysis data, Effective wave height, Wind wave, Swell index
