【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。
[Abstract]:Based on the assimilation simulation results of small and medium scale numerical analysis of QuickSCAT satellite data, the wind speed characteristics of two different gulfs in Bohai Sea, namely Liaodong Bay and Dalian Bay in 2008, are analyzed and compared. Firstly, the reliability of QuickSCAT satellite data assimilation simulation data is verified. Comparing with Fnl data and meteorological station data, it is found that QuickSCAT data is closer to the measured data, which is suitable for regional data research. It is found that the wind speed of the larger Liaodong Bay is larger than that of Dalian Bay, which is obvious in April and October. The results show that the diurnal variation of wind speed in the two bays is opposite to that in the early morning, and the variation from day afternoon to night tends to be similar. The frequency and duration of gale in Liaodong Bay is larger than that in Dalian Bay, and the occurrence of strong wind in Dalian Bay lags behind that in Liaodong Bay.
