【摘要】 利用 MITgcm 正压模型,计算了洪泽湖在理想定常风应力作用下的湖水流动情况, 计算结果表明：(1)在没有径流的情况下,风应力可看作是水体循环的主要驱动力；(2) 在水平方向上,表层及次表层流向与风向基本一致,第3层的流向则随着时间的不同而变化较大,第4～6层可以看作是上述表层及次表层的回流；(3)在南风持续作用下,在垂向上,南北方向流动很快达到稳定,而东西方向流动则变化很大,在24h 内表层及次表层流均有流向的转交；(4)不同点位达到(准)稳定流动所需的时间不同,在给定定常风场作用下,东部湖区达到(准)流动稳定状态需要约16h,而南部湖区则需要很短的时间．更多还原

【Abstract】 A study of wind-driven current in Hongze Lake is carried out by Model MITgcm and we arrive at some important conclusions.These are:（1） wind stress can be regarded as the driving force of the water circulation flow;（2） the water flow direction of the surface and the subsurface water are as the same as the wind moves,while on the 3^rd layer the direction changed much with time,and that of the fourth and below layers is nearly on the contrary or is almost inversed;（3） Under the wind, meridional water flow will attain stability soon while the zonal circulation varies much that direction of flow on both surface and subsurface layer change into the contrary one during the 24 hours,（4） it takes different time for water flow at different area to attain the stability,that in the east part of Hongze lake it is about 16 hours while in the south part it costs only a few hours.更多还原
