摘要
本研究利用2003-2022年江苏省的海浪灾害数据对灾害形势进行分析,并采用第三代海浪模型SWAN对江苏海域海浪特征进行模拟,收集江苏沿海苏北浅滩和盐城外浮标实测海浪数据对模型结果进行比对验证.对江苏海域海浪灾害特征的研究和分析结果表明:整个江苏沿海基本以东北和东南向浪为主,大浪占比较大出现在8-9月,江苏沿海海域多年一遇有效波高沿着岸线呈南北向带状分布,由北向南的梯度逐渐增大,致灾方面,台风浪对海洋经济的影响较大,而气旋浪和冷空气浪对人员伤亡的危险性更大.
Abstract
In this paper,the wave disaster data of Jiangsu province from 2003 to 2022 is used to analyze the disaster situation,and the third generation wave model SWAN is used to simulate the wave characteristics in the sea area of Jiangsu province,the model was validated by collecting observed buoys wave data from the Subei Shoal and off the Yancheng coast of Jiangsu province.The results show that the northeast and southeast waves are the main waves along the coast of Jiangsu province,and the large waves occur from August to September,The effective wave height in the coastal area of Jiangsu province is distributed along the coastline in a north-south direction,and the gradient from north to south also increases gradually.In disaster-causing aspect,typhoon waves have a greater impact on the marine economy,while cyclone waves and cold air waves have a greater risk of casualties.
