摘　　要：为了给航海、岛礁海浪发电、防灾减灾等提供海浪信息,促进军地海洋建设,利用CCMP(Cross-Calibrated Multi-Platform)风场驱动第三代海浪模式WAVEWATCH-Ⅲ(WW3),对2013年3月上中旬发生在中国海的一次强冷空气海浪场过程进行数值模拟,结果表明:本次冷空气给东中国海带来明显的大浪过程,其中高于4m的海浪区域基本维持在黄渤海区域以及东海北部,冷空气在移动过程中涌系的传播较为明显;对于低纬海区,冷空气的影响主要是通过台湾海峡和巴士海峡的地形对南海北部浪场产生较大影响,但相较于东中国海区,南海受冷空气大浪影响较弱.In order to provide reference for navigation, wave power generation, disaster prevention and reduction, a big wave process caused by cold air on March 2013 was simulated, based on the WAVEWATCH-Ⅲ （WW3） wave model forced by Cross-Calibrated, Multi-Platform （CCMP） wind data, in hope of improving the army and local marine construction. The results show that, a big wave is generated by this cold air process. The significant wave height greater than 4 m is mainly distributed in the Yellow Sea and the north of the East Sea. During the moving process of cold air, the swell exhibits propagation feature obviously. In the low latitude waters, the cold air generates big wave in the north of the South China Sea under the impact of the topog raphy of Taiwan Strait and Bashi Strait. The cold air has a more significant impact on the East Sea than that on the South China Sea.
