摘　　要：由数值模拟和实测结果比较得出 ,广西沿岸主要海湾余流场流型及流速变化直接与风力的强度和风力作用的方向有关。在湾口开阔海区 ,风力作用强度加强 ,余流流速较大 ;在湾顶狭窄海区 ,风力作用强度减弱 ,余流流速较小。余流最大流速为 10 cm / s～ 15 cm / s,余流最小流速为 1cm / s～ 2 cm /In terms of the comparison of numerical computation and field observation, it is found that the pattern of residual current fields and current velocity relate directly to strength and direction of wind in the key bays along the coast of Guangxi. At the broad area around mouth of bay, the residual current velocity is getting faster with increase of wind strength; at the narrow area of around the top of bay, the residual current velocity is getting slower when decline of wind strength. The maximum velocity of residual current ranges from 10 cm/s to 15 cm/s, and the minimum velocity of residual current ranges from 1 cm/s to 2 cm/s.
