一、前言在我国近海,一年四季受气旋影响频繁。尤其是黄海和东海常有温带气旋通过,春季最多,夏季次之(表1)。当气旋通过时,对附近海区的天气影响很大,常使海上出现大浪、大涌(H1/3≥3.0米)。特别是春、秋两季,发展强烈的入海气旋与南下冷空气相配合,常常给海上带来恶劣的天气及灾害性的浪场分布,使得近海的渔业生产、海上航行及各项海工作业面临很大威胁。因此,对气旋浪场的分布进行探讨是十分必要的。本文使用了10年的海浪实况资料,选出了87个气旋过程,将气旋分为三种类型进行分析描述,并根据数理统计原理,建立了气旋浪波高的相关计算式。
First, the preface In our country offshore, cyclones are frequently affected throughout the year. Especially the Yellow Sea and the East China Sea are often temperate cyclones, the spring up, followed by summer (Table 1). When the cyclone passes, it has a great influence on the weather in the nearby sea area, often resulting in large waves at the sea and Tai Chung (H1 / 3 ≥ 3.0 meters). Especially in spring and autumn, the strong inflow of the sea into the sea and the cooperation of the south cold air often bring bad weather and disastrous wave field distribution to the sea, making the offshore fishery production, offshore navigation and marine operations Faced with a great threat. Therefore, it is necessary to explore the distribution of cyclone waves. In this paper, we use 10 years of ocean wave actual data, select 87 cyclone processes, classify cyclones into three types for analysis and description, and establish the related formulas of cyclonic wave height based on mathematical statistics.
