This study aims to analyze the effect of the differences in intensity and track of tropical cyclones upon significant wave heights and direction of ocean waves in the southeast Indian Ocean. We used the tropical cyclone data from Japan Aerospace Exploration Agency (JAXA) starting from December 1997 to November 2017. The significant wave height and wave direction data are reanalysis data from Copernicus Marine Environment Monitoring Service (CMEMS), and the mean sea level pressure, surface wind speed, and wind direction data are reanalysis data from European Center for Medium-Range Weather Forecasts (ECMWF) from December 1997 to November 2017. The results show that the significant wave height increases with the increasing intensity of tropical cyclones. Meanwhile, the direction of the waves is influenced by the presence of tropical cyclones when tropical cyclones enter the categories of 3, 4, and 5. Tropical cyclones that move far from land tend to have higher significant wave height and wider affected areas compared to tropical cyclones that move near the mainland following the coastline.
本研究旨在分析热带气旋强度和路径的差异对东南印度洋有效波高和海浪方向的影响。我们使用了日本宇宙航空研究开发机构（JAXA）自 1997 年 12 月至 2017 年 11 月的热带气旋数据。有效波高和波向数据是哥白尼海洋环境监测服务（CMEMS）的再分析数据，平均海平面气压、海面风速和风向数据是欧洲中期天气预报中心（ECMWF）的再分析数据，时间范围为 1997 年 12 月至 2017 年 11 月。结果表明，有效波高随热带气旋强度的增加而增加。同时，当热带气旋进入 3、4 和 5 类时，热带气旋的存在会影响海浪的方向。远离陆地移动的热带气旋与沿大陆海岸线移动的热带气旋相比，其有效波高更高，受影响的区域更广。
