摘要
研究和讨论了海气相互作用过程中海冰演变的物理过程；大气和海洋对海冰的热力作用以及冰内物理过程；大气和海洋热力学参数对冰厚和密集度等协请参数的影响和上述物理过程的数学处理。计算了冰面与水面能量收支，并分析海体热力增长函数的特征；将热力模式与动力模式连接构成热动力模式。对渤海1989－1990年度海冰进行数值模相。结果表明，考虑热力过程的热动力模式，对类似于1990年2月12－18日海冰融化过程显示出明显的优越性，模拟结果与卫星和海上观测相符合。
This paper deals with the elevation of sea ice, the therma1 effect of atmosphere and ocean on sea ice, the physical processes inside ice, and the influence of atmos-pheric and oceanic factors on sea ice parameters (ice thickness or concentration).Tbe thermal growth rate of sea ice is analysed by calculating the energy flux bud-get over sea and ice. A thermodynamic-dynamic mode1's simulation of the Bohai Sea ice during the winter of 1989-199O showed that for the melting process of sea ice from February l2-l8, 199O, this model with thermal processes has advantages over a mode1 which does not include thermal processes. The simulation results are in good agreement with satellite images and ship observations.
