| 摘要: |
| 为了解杭州湾北部波浪特性,利用杭州湾北部一年实测波浪资料,统计分析该地区的波参数变化特征,运用回归分析获得波参数之间的相关关系,并用谱参数及波谱形态分析了实测波浪频谱的变化特性。结果表明,与杭州湾南部海域波浪特性明显不同之处是热带气旋对本观测水域波浪的影响强度大于冬季季风的影响强度,较大波浪主要由热带气旋引起,并且路径相似的热带气旋在杭州湾南、北部测点引起的最大波浪其参数较为接近。研究水域常浪向分布在东东北至东南向,强浪向主要分布在东东北方向。研究成果可为河口海湾相关工程的设计建造和沿海防灾减灾提供重要参考。 |

| Abstract: |
| To understand the wave characteristics of northern Hangzhou Bay, We analyzed statistically the variation characteristics of measured wave parameters in the northern Hangzhou Bay, East China Sea based one-year observation data, from which correlations among wave parameters were obtained by regression, and the variation characteristics of measured wave spectrum were analyzed with spectral parameters and spectral morphology. Results show that the effect of tropical cyclones on the observed waves is stronger than that of winter monsoon, which is obviously different from that of the southern Hangzhou Bay. Large waves are mainly caused by tropical cyclones, and the parameters of the maximum waves induced by tropical cyclones of similar path in the southern and northern wave stations of Hangzhou Bay are similar. The direction of dominant wave of the study area is from ENE to SE, while the strong wave direction is ENE. This study provided an important reference for design and engineering of marine constructions, and for coastal disaster prevention and mitigation. |
