| 摘 要： | 为了验证第三代海浪模式WAVEWATCH Ⅲ V5.16中不同海冰损耗源项在秋季波弗特海对海冰存在下海浪的模拟能力，建立自波弗特海至马更些河河口的两级嵌套海浪模型，对2014年8月1日至9月31日该海域北极风暴作用下的暴风浪有效波高进行模拟研究，并利用浮标实测数据对模拟结果进行对比分析。结果表明，在应用于大范围海域、缺乏海冰有效剪切模量、黏性系数等属性参数的前提下，离海冰较近、海浪能量受海冰控制作用较为明显的区域，各海冰源项中IC1源项表现最好，能够表现出更加符合波弗特海海域特定的冰情、冰况的能量耗散特征。

| Abstract: | To evaluate the wave simulation capacity of the sea ice dissipation source terms in the third-generation wave model WAVEWATCH III V5.16, a nested wave model covering the area from Beaufort Sea to Mackenzie River Estuary is established to simulate the storm waves under the effect of Arctic storms from August 1st to September 31st, 2014. Simulated significant wave heights are calibrated using the measurements from SWIFT buoy. Results show that in the absence of ice data (i.e., with default model settings), in the areas near the ice edge, where wave energy is strongly controlled by sea ice, the performance of IC1 ice source item is the best, of which the results are more in line with the specific ice conditions in the Beaufort Sea. |
