台风浪数值模拟中风场权重系数分析

摘要

The gradient wind field calculated by the model of field pressure was combined with the background wind field as a synthetic wind field to drive SWAN to simulate the East China Sea area.Different weighting coefficients were used to simulate 6 typhoons which occurred in this area.After comparing and analyzing the simulation results,the improvement measures of weight coefficients were proposed.The structure of wind field and the simulation accuracy of wave field were optimized.%文章采用藤田气压模型与背景风场构造的合成风场,驱动SWAN波浪模型,模拟不同权重系数下经过东中国海海域的6个北上行台风,在对比分析模拟结果之后,提出了权重系数的改进措施,有效的优化了风场的构造方式以及波浪场的模拟精度.
