摘　　要：利用山东省划分的沿海12个海区代表站和部分海岛站资料,6艘渤海和黄海救助船资料,验证了2010年11月以来冬春季海区大风过程(≥6级)中,烟台北部沿海和威海南部沿海站大风资料的可用性,并对渤海湾、渤海中部海区、黄海北部海区和山东沿海大风进行了对比分析,得到以下结论:(1)渤海湾海区,滨州北部和东营北部沿海站均比海面风速偏小。(2)渤海中部海区,当天气系统为低槽冷锋时,东营东部、潍坊北部、烟台北部和烟台西部沿海站均比海面风速偏小。(3)黄海北部海区,在统计时段内,成山头站非常接近海面风速,其次是长岛县大黑山比海面风速小3 m·s-1左右。By using the 12 coastal sea areas representative stations and island station data over Shan- dong province, and six rescue ship data over Bohai and Huanghai sea, the availabity of gale data from is- land stations in northern Yantai and southern Weihai was verified in the selected gale processes since No- vember,2010, moreover, the gale processes in Bohai Bay, central Bohai, northern Huanghai and coastal Shandong were comparatively analyzed. Results show that （ 1 ） the mean absolute errors about gale in Bo- hal Bay, northern Binzhou and northern Dongying are both less than that over sea surface. （2） In the middle Bohai sea areas, when the weather system is low pressure-cold front, the wind speed of eastern Dongying, northern Weifang, northern Yantai and western Yantai are all less than that over sea surface. （3） The wind speed of Chengshantou station is very close to sea surface speed, and the second is Daheis- hanstation with mean absolute error of 3 m·s-1.
