摘　　要：利用QuickSCAT卫星资料的中小尺度数值分析同化模拟结果,对渤海两个大小不同的海湾:辽东湾与大连湾2008年季节代表月的风速特征进行分析对比。首先对QuickSCAT卫星资料同化模拟数据的可靠性进行了验证,与Fnl资料分别同气象站实测值对比发现QuickSCAT资料更靠近实测值,适合做区域数据研究。对两个海湾区域风速研究发现,面积较大的辽东湾风速基本大于大连湾,这种现象在4月与10月表现显著;而对两海湾风速日变化对比结果显示,4个月大致均表现为凌晨二者变化相反,白天下午至夜晚变化趋于相似。从大风情况上看,辽东湾出现大风的频率和持续时间基本大于大连湾,大连湾的大风发生情况普遍要滞后于辽东湾。By using the numerical assimilation simulation results analyzed by QuikSCAT satellite data with middle and small scale,the wind speed features of two bays: Liaodong Bay and Dalian Bay in season-representing typical months of 2008 were comprehensively analyzed.Firstly,the reliability of assimilation simulation of QuikSCAT satellite data was verified,which found that QuikSCAT data are closer to the measured values and is more suitable for regional data research.Research on wind speed of two bays found that the wind speed of Liaodong Bay is basically larger than that of Dalian Bay because of the former's greater area,especially in April and October.The comparison of daily variation of wind speed of two bays show that an opposite change trend exists in the morning,but from afternoon to night the trend becomes similar.Moreover,the gale in Liaodong Bay is frequent and longer and earlier than that inDalian Bay.
