波浪数学模型中谱分割功能的应用
Implementation of spectral partition in wave models
摘要
Abstract
In ocean wave simulation. Significant wave heights of the total spectrum are usually considered as the final results and are compared with observed wind waves during numerical wave model calibration. However, a real spectrum usually includes both the local wind waves and the swells coming from deep sea; therefore, the significant height is not equal to wind wave height in physical meaning. The wave models WAVEWATCH-III and M1KE21-SW are applied to hindcast the ocean wave field of the Northwest Pacific. Meanwhile, the numerical approach of spectral partition can separate swells and wind waves from the total spectrum. Comparisons between calculated wave heights and measurements show that the function of spectral partition can increase the accuracy of simulation and improve the integrity of information of the wave energy status. In addition, WAVEWATCH-III gives a better partition result than MIKE21-SW. Therefore, it is reasonable to apply spectral partition in numerical simulations relating to wind-generated wave that contains swell.关键词
