An Analysis on the Characteristics of Wind Distribution in the Coast of Busan Using AWS Data

Abstract

Wind velocity and wind direction are very important in the viewpoint of ship's safety and stability of port structure. The characteristics of wind distribution in the coast of Busan are analyzed for 10 years from 1997 to 2006 using AWS(Automatic Weather System) data. The characteristics of wind distribution of Miryang, is not affected by the land and sea breeze are also examined to understand clearly the characteristics of wind distribution in the coast of Busan. The mean wind velocity in the coast of Busan is stronger than that of Miryang. The mean wind velocitie⁳ at Youngdo and Gadukdo stations of Busan are stronger about 2.0 times than those at IlGwang, Haeundae and Daeyeon stations. The correlation a states show that the variation tendencies of monthly mean wind velocitie in the coast of Busan are very similar. The maximum monthly mean velocitie⁳ in the coast of Busan are recorded in September. This re⁳ult is closely related to the influence of typhoon. The maximum instantaneous wind velocitie⁳ are also strong at Youngdo and Gadukdo stations and the peaks of maximum instantaneous wind velocit are observed mainly from August to September. In the coast of Busan, the SW'ly-NNE'ly wind are prevailing in the winter and the SW'ly and NE'ly wind are predomisnt in the spring. w that the vs of wind direction in the summer and athumn are similar with those in the spring and winter, respectively.
