摘要：
Based on the observational data and numerical simulations, the impacts of typhoon "Yagi" and "Rumbia" at Chaohu Basin were analyzed in this paper. When "Yagi" and "Rumbia" passing, they produced a large wind speed and wind wave at the surface of Lake Chaohu, inducing the greatest impact at the east part of the lake and then followed by the middle and west part of the lake. The maximum significant wave heights were 0.68, 0.67 and 0.48 m, and the maximum average wave period were 2.25, 2.33 and 1.95 s, produced by the transiting of Typhoon "Yagi" in east, mid-, and west part of Lake Chaohu, respectively. While the maximum significant wave heights could reach 1.50, 1.47 and 1.18 m, and the maximum average wave periods could reach 2.99, 3.04 and 2.74 s when typhoon "Rumbia" passed through Lake Chaohu Basin. The mid-area between the east and middle of the lake was mostly influenced by typhoon, and the impact on the east part was the most significant, followed by the middle and the west parts of the lake. Due to the large water depth and long wind fetch, the lake middle zones are often the areas with the largest wave intensity. © 2020 by Journal of Lake Sciences.
