摘要:

文章利用珠江口长达1年的实测海浪资料, 对珠江口海浪基本要素、大浪过程以及与热带气旋活动的关系进行统计分析, 选取强台风“韦森特”过程进行研究。结果表明: 珠江口波浪以0~2级波高为主, 出现频率达76%, 3级波高次之, 出现频率为22%; 平均波高的月变化幅度较大, 大浪多出现在夏、冬季, 与热带气旋活动和冷空气过程密切相关; 常浪向为SE向, 出现频率为29%, 强浪向为SSE向, 一般由热带气旋引起; 涌浪在秋、冬季出现频率较低; 在春、夏两季出现频率稍高。强台风“韦森特”期间, 最大浪高达3.93m, 台风浪经历了涌浪—混合浪—风浪—混合浪的过程, 波型变化与一般台风浪波型的演变规律较为一致。

Abstract:

Based on the one year wave data collected continually at the station of the Pearl River Estuary, statistical analysis of wave characteristics was conducted. The results show that the frequency of the wave height that was below 0.5 m was 76%. The month-to-month variation was quite notable. The bigger waves occurred mainly in summer and winter, which were closely related to tropical cyclones and cold air. The direction of higher frequency waves was SE, and the frequency reached 29%. The direction of strong wave was SSE, which was generally caused by tropical cyclones. During Typhoon Vicente, the wave height increased rapidly, with the maximum wave height reaching 3.93 m. The pattern of typhoon wave was in accordance with the general evolution of typhoon wave type.
