利用辽东湾JZ2 0 2海域冰期气象、水文和海冰的实测资料和海冰数值模拟结果 ,对海冰漂移过程中风和流的拖曳力、海冰内力、科氏力和海面倾斜力要素的基本特征进行了分析 ;采用海冰热力—动力模式对 1999年 2月 3日 6 :5 0至 2月 5日 6 :5 0间辽东湾海冰进行了 48h数值模拟 ,对并JZ2 0 2海域的海冰动力要素进行了对比分析。发现海冰内力、风和流的拖曳力为同一量级 ,海面倾斜力和科氏力明显较小 ,其均值的比例关系依次为 14.7∶18.8∶32 .6∶1.5∶1.0 ;海冰各动力要素相互影响 ,共同决定了海冰的漂移速度和运动轨迹
Based on the data of meteorological, hydrological and sea ice and the numerical simulation of sea ice during the ice age of JZ2 0 2 in Liaodong Bay, the basic elements of the drag force, the internal force of sea ice, the Coriolis force and the sea surface tilt force during the drift of sea ice The sea ice ice thermal-dynamic model was used to simulate the sea ice in Liaodong Bay from 6: 50 to 6: 500 on February 3, 1999, and 48 hours in JZ2 0 2 Sea ice power factor were compared. It is found that the drag forces of sea ice, wind and stream are of the same order of magnitude, and the slope force and Coriolis force on the sea surface are obviously smaller. Their average ratios are 14.7: 18.8: 32.6: 1.5: 1.0 respectively. Elements of mutual influence, together determine the drift speed of ice and motion trajectory
