风对北部湾入海径流扩散影响的研究
Wind Effects on Spread of Runoffs in Beibu Bay
摘要
Abstract
By using the FVCOM numerical model and the latest runoff data of the Red River in the Beibu Gulf,diffusion characteristics of the runoffs were simulated in the summer of 1988 and 1989,since there were apparent difference in wind distribution in summer in these two years.Furthermore,the current circulation of Beibu Gulf in winter was simulated with the mean wind field in winter and the runoffs.The conclusions are as follows:(1)In August 1988, the strong southwest wind formed a strong northern coastal current in the west bank of the Beibu Gulf,and a cyclonic circulation near the Weizhou Island in the east.Accordingly,there were a weak anti-cyclonic circulation in the north of the Beibu Gulf and a larger cyclonic circu-lation in the middle.(2)In August 1989,the southwesterly wind was weaker than in August 1988,and the surface runoffs of the Red River went mainly to the south along the west bank of the Beibu Gulf.The residual current from the Qiongzhou Strait formed a large cyclonic circula-tion in the northern area of the Beibu Gulf.At the same time,there was a strong cyclonic circu-lation in the southern area of the Beibu Gulf.(3) In the winter,the Beibu Gulf reveals mainly cyclonic circulation driven by strong northerly wind in winter.An anti-cyclonic circulation ap-pears only in the northwest waters of Beibu Gulf.关键词
