【摘要】:利用QuickSCAT衛(wèi)星資料的中小尺度數(shù)值分析同化模擬結(jié)果,對(duì)渤海兩個(gè)大小不同的海灣:遼東灣與大連灣2008年季節(jié)代表月的風(fēng)速特征進(jìn)行分析對(duì)比。首先對(duì)QuickSCAT衛(wèi)星資料同化模擬數(shù)據(jù)的可靠性進(jìn)行了驗(yàn)證,與Fnl資料分別同氣象站實(shí)測(cè)值對(duì)比發(fā)現(xiàn)QuickSCAT資料更靠近實(shí)測(cè)值,適合做區(qū)域數(shù)據(jù)研究。對(duì)兩個(gè)海灣區(qū)域風(fēng)速研究發(fā)現(xiàn),面積較大的遼東灣風(fēng)速基本大于大連灣,這種現(xiàn)象在4月與10月表現(xiàn)顯著;而對(duì)兩海灣風(fēng)速日變化對(duì)比結(jié)果顯示,4個(gè)月大致均表現(xiàn)為凌晨二者變化相反,白天下午至夜晚變化趨于相似。從大風(fēng)情況上看,遼東灣出現(xiàn)大風(fēng)的頻率和持續(xù)時(shí)間基本大于大連灣,大連灣的大風(fēng)發(fā)生情況普遍要滯后于遼東灣。
[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.
