Abstract:By using the 12 coastal sea areas representative stations and island station data over Shandong province, and six rescue ship data over Bohai and Huanghai sea, the availabity of gale data from island stations in northern Yantai and southern Weihai was verified in the selected gale processes since November, 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 Bohai 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 Daheishanstation with mean absolute error of 3 m·s-1.
