| 摘 要： | 建立了一个包含潮流作用的准定常海冰动力学模式，利用实测风资料和计算的潮流场对辽东湾中部的冰块漂移过程进行数值模拟，模拟的冰块漂移过程和实况基本一致。表明模式具有反映冰漂移过程动力特征的能力。通过对各动力因子的数值试验，说明引入潮流作用的必要性，并分析了各动力因子在冰漂移过程中的作用。

| Abstract: | on the basis of the natural geographic condition of the Bohai Sea a dynamicsea ice model is developed that differs from previous dynamic sea ice models in themomentum balance forces that determine the drift process of sea ice. In the modelthe water stress is considered to be the tidal current force, and tidal current changesperiodically in both the speed and the direction. The simulated movement of sea icefloe in the Bohai Sea are agreed with observational data. lt has been shown that themodel can reconstruct the essential characteristics of sea ice floes movement in theBohai Sea.Sensitivity tests carried out to gain understanding of the effects of various forceson sea ice movement showed that the effect of each force on sea ice movement isdifferent. The wind force is one of the driving forces of sea ice movement, so thewind force is very important in the long distance drift of sea ice. Though tidal curr-ent is periodic, its effect on the sea ice movement cannot be neglected, specially fordetermining the speed and direction of sea ice floe at all times in the Bohai Sea.The effect of the internal ice stress and Coriolis force on sea ice movement are lessthan that of the wind and tidal current. The internal ice stress decreases the speedof sea ice floe movement. The Coriolis force changes the direction of sea ice mov-em ent. |
