基于Aden和 Kerker的同心散射理论, 将冰 -水混合云看成由众多冰水同心球粒子构成, 对冰 -水混合云的光辐射特性进行了研究。计算了冰 -水混合云的消光、散射、吸收效率因子以及单次散射反照率, 并讨论了冰水所占比例以及粒子尺寸分布对冰 -水混合云散射特性的影响。在此基础上, 采用离散纵标法对辐射传输进行了计算, 得到了冰 -水混合云在红外波段的反射函数和透射函数。

The optical properties of the Ice-water mixed clouds consisting of a large amount of ice-water concentric particles were studied based on the theory of concentric scattering. Computations of the extinction, scattering, absorption efficiency factor and single scattering albedo were performed. It is also discussed that the change of the proportion of ice-water and the influence on the scattering property of ice-water mixed clouds. Furthermore, the discrete ordinate method was applied to study the radiation transfer and the Reflection function, and transmission function of the ice-water mixed cloud was obtained.
