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。

Abstract:

This paper deals with the elevation of sea ice, the thermal effect of atmosphere and ocean on sea ice, the physical processes inside ice, and the influence of atmospheric and oceanic factors on sea ice parameters (ice thickness or concentration). The thermal growth rate of sea ice is analysed by calculating the energy flux budget over sea and ice. A thermodynamic-dynamic model’s simulation of the Bohai Sea ice during the winter of 1989 - 1990 showed that for the melting process of sea ice from February 12 - 18, 1990, this model with thermal processes has advantages over a model which does not include thermal processes. The simulation results are in good agreement with satellite images and ship observations.

Key words: Sea ice, Thermal processes, Numerical simulation, Thermodynamic-dynamic model
