摘要 在1988年春季（淡水径流量低的时期）和1989年夏季（淡水径流量高的时期），对Knight Inlet整个水柱（包括基台的上入口和下入口）进行了为期一个月的流速、温度和盐度观测。使用 S4 海流计在 2、4、6、9 和 12 m 的深度进行测量，使用剖面海流计在 200 m 左右的深度进行测量，使用 Aanderaa 海流计在 200 m 以上的深度进行测量。风速计部署在入口沿线的两个位置。入口的横向集成二维数值模型采用 Mellor 和 Yamada 2.5 级湍流闭合方案，并考虑了风、潮汐和淡水径流的综合影响，已用于对入口处的速度和密度场进行 30 天的模拟。模型中的垂直坐标经过转换，即使潮汐范围很大，也可以在表面附近获得非常精细的垂直分辨率...
Abstract During spring 1988 (a period of low freshwater runoff) and summer 1989 (a period of high freshwater runoff), month-long observations of velocity, temperature, and salinity were made throughout the water column in Knight Inlet, both up-inlet and down-inlet of the sill. Measurements were made at depths of 2, 4, 6, 9, and 12 m using S4 current meters, at depths down to about 200 m using profiling current meters, and at depths deeper than 200 m using Aanderaa current meters. Anemometers were deployed at two locations along the inlet. A laterally integrated, two-dimensional numerical model of the inlet that uses the Mellor and Yamada level 2.5 turbulence closure scheme and that accounts for the combined influence of the winds, tides, and freshwater runoff has been used to produce 30-day simulations of the velocity and density field in the inlet. The vertical coordinate is transformed in the model so that very fine vertical resolution can be attained near the surface even though the tidal range is larg...
