由于海冰热力过程太复杂，难于精确计算冰面和水面热量收支方程中的每一项，并且净热量收支比每项小得多，因此难以确定海冰热力一动力模式中的净热通量。本文根据渤海的水文气象观测，详细分析了太阳短波辐射、长波辐射、云量、感热和潜热等对海冰热力增长函数的贡献，给出了一种海冰热力过程的参数化方案。并选取２个典型的个例进行了对比研究。模拟结果表明，该参数化方案能较好地模拟渤海海冰的热力过程。
Because of the complexity of sea-ice thermodynamic processes, it is difficult to accurately calculate each of the thermal and water budget equations for ice and surface, and the net heat balance is much smaller than each, making it difficult to determine the net heat in the sea-ice thermodynamic-dynamic model Flux. Based on the hydrological and meteorological observations in the Bohai Sea, this paper analyzes in detail the contributions of shortwave radiation, longwave radiation, cloudiness, sensible heat and latent heat to the thermodynamic growth of sea ice and gives a parametric scheme for the thermodynamic process of sea ice. Two typical cases were selected and compared. The simulation results show that this parameterization scheme can simulate the thermal process of sea ice in the Bohai Sea well.
