0920号超强台风Lupit海浪数值模拟试验

The Wave Numeric Simulation of 0920 Super Typhoon Lupit

摘要: 基于WAVEWATCH III v3.14海浪数值模式，建立混合双向嵌套网格，分别采用CCMP和GDAS海面10m风场资料，模拟2009年10月西北太平洋第20号超强台风Lupit的海浪场有效波高，对比分析不同风场资料对台风海浪模拟的影响，并根据浮标观测数据分析模拟的效果。结果表明，WAVEWATCH III模式能够较好的模拟台风海浪场分布形势，模式对风场资料具有较强的敏感性，基于融合了多种观测资料的CCMP高分辨风场资料所模拟的结果更为准确。

Abstract: Based on 10 meters up ground wind data of CCMP and GDAS, the significant wave height distribu-tion of 0920 Super Typhoon Lupit on Northwest Pacific was simulated by the wave numerical model WAVEWATCH III v3.14. Otherwise, the influence from different wind data and the effect evaluation of wave simulation was studied. The result shows that, firstly, WAVEWATCH III model simulates typhoon wave well, but with a strong sensitivity to the wind data. Secondly, due to the integration of a variety observations and a higher spatial resolution, CCMP wind data lead to much more accurate wave simulation results.
