摘要

采用现场测量方法分析浙江近岸海域在极端天气条件下的大浪特征,比较分析台风浪和寒潮大浪的差异,对台风浪和寒潮大浪过程的波参数进行统计分析、回归分析,结合风资料探讨波参数与谱变化特性,1年内共观测到5次台风浪过程和1次寒潮大浪过程。研究表明：涌浪作用较大时,波高和风速几乎无相关性;当风浪作用达到一定程度时,波高和风速呈同步变化趋势;研究海域的台风浪为区域内风浪和外海涌浪组成的混合浪,单峰谱、双峰谱和多峰谱为其波浪谱型,双峰谱最多;寒潮大浪过程为典型的风浪过程,其谱型为单峰谱。

Abstract

The wave characteristics under extreme weather conditions in the nearshore waters of Sanmen Bay in Zhejiang Province are presented based on field observation, and the differences between typhoon wave and cold wave are investigated. The observed wave parameters during typhoon and cold snap are analyzed by statistical analysis and regression analysis, and the variations of wave parameters and wave spectra during large wave processes are discussed. 5 typhoon wave processes and 1 cold wave process are observed during the whole year. The results show that when the low frequency swells are in a dominant position, the wave height has little correlation with the wind speed. However, when the high frequency wind seas are relatively large, the wave height and wind speed change synchronously. The sea waves during typhoons are mixed waves consisting of swells and wind seas. The wave spectra are mainly double-peaked, and there are also single-peaked spectra and multi-peaked spectra. The large waves during the cold snap are wind seas, and the wave spectra are mainly single-peaked.
