摘　　要：根据2005年大连金州气象站的常规风向风速资料对金州地区的海陆风特征进行了分析,并应用MM5v3模式模拟了海陆风发生时的风场变化,计算了海风和陆风延伸到内陆和海面的距离。结果表明:大连金州地区海陆风的发生主要受太阳辐射强度和海陆温差的影响,在春夏季晴朗天气条件下海陆风发生的频率较高、平均风速较大,而海陆风的延伸距离主要受风速影响。Based on the windward and wind speed data of routine weather stations in 2005, the characteristics of the sea-land breeze were analyzed in Jinzhou area of Dalian. The changes of the wind field were simulated by MM5v3 model when a sea-land breeze took place. And the distances of the sea breeze and the land breeze extend- ing to the land and the sea were calculated, respectively. The results indicated that the occurrence of the sea-land breeze was mainly influenced by the sun radiant intensity and the temperature difference between sea and land. Under the clearness weather conditions in spring and summer, the frequency of sea-land breeze was high, and the average wind speed was very large. While the extended distance of the sea-land breeze was mainly influenced by the wind speed.
