两种海浪模式对一次台风浪过程的模拟分析
Contrast Simulation of Typhoon Waves in the China Sea
摘要
Abstract
In this thesis, the wave field caused by the typhoon “KOMPASU” was simulated by using WW3 (WAVEWATCH-Ⅲ) wave model and SWAN (Simulating WAves Nearshore) wave model, with CCMP (Cross-Calibrated, Multi-Platform) wind field as the driving field. By analyzing the characteristic of typhoon waves and contrasting the simulation ability of the two wave models, a reference for preventing disasters, reducing damages and studying typhoon waves will be provided. Then the simulation results were contrasted. Results show that:1) Both WW3 and SWAN wave model can well simulate the typhoon wave field happened on the East China Sea . The changing of wave directions was accordant with that of winds . The significant wave height (SWH) has good accordance with sea surface wind speed. 2) From correlation coefficient, Bias, RMSE, MAE, the SWH of SWAN and WW3 have high precision. The SWH of SWAN is slightly lower than the observation wave height; the SWH of WW3 is closer to the observation wave height. 3) Typhoon can cause big wave as high as 5m around Ryukyu Islands. After typhoon wave enters the East China Sea, wave height and wind speed increase to some extent. When the typhoon passes through the Korean peninsula along the northwest route, getting a huge influence of peninsula topography, both the wind speed and wave height reduces obviously.关键词
