摘要
本文从海冰的光学特性出发,利用平行分层大气传输方程加上特定的边界条件推导出海冰反射率、厚度及波长三者之间的关系。使用实测数据对其参数进行修正,建立了数学模型。用所建数学模型计算的辽东湾海域不同厚度海冰的反射率值与经过大量实验的结果相对照,误差平均值为0.035。因而,这一数学模型对辽东湾海域海冰的理论研究很有实用价值和应用前景。对我国海冰的研究工作起到一定的推动作用。同时利用数字计算机计算加快了计算速度,为海冰数值预报奠定了基础。
In this paper,the relation among reflectance,thickness andwavelength is derived from the optical properties of sea ice and equation oftransfer for plane-parallel scattering atmosphere with the special boundarycondition.Using the really measured data to revise the model parameters,amathematical model was established.Utilizing this model,we can calculatetheoretically the reflectances of the different thickness of sea ice in LiaodongGulf and compared these reflectances with a vast amount of experiment res-ults to verify the calculated ones being reliable.Therefore the mathematicalmodel behaves the practical value and the applied vistas for the theoreticalresearch of sea ice in Liaodong Gulf and will effect forward on the nationalresearch of sea ice.Simultaneously making use of the digital computer tocompile program is accelerating the operation rate and increasing the accur-acy and reliability.It laid a foundation of numerical forecast of sea ice.
