为研究中纬度卷云的光学散射特性，介绍了冰晶粒子谱的双峰分布模型及中纬度卷云冰水含量的分布模型，并结合冰晶形状分布，建立起一个简单的研究卷云特性的模型，而后计算了在0．5～10μm范围内中纬度卷云的的消光系数、散射系数、吸收系数。计算结果表明：中纬度卷云温度上升时，卷云的光学特性参数随温度变化行为的基本一致；中纬度卷云的冰水含量及冰晶粒子的平均最大尺寸是影响中纬度卷云的光学散射特性的关键因素。

A simple model for mid-latitude cirrus is developed based on bio-model size distribution parameterization for middle latitude cirrus, a model for IWC（ice watcr content） of mid-Iatltude cirrus, and Based on ice crystal types distribution. Absorption coefficient, scattering coefficient and extinction coefficient of mid-latitude cirrus are computed by this model for infrared wavelength from 0. 5 μm to 10 μm. The results indicate that optical properties parameters of mid-latitude have consistent behavior with temperature of cirrus increasing; IWC and mean maximal size of ice particles of mid-latitude cirrus are the two factors that influence on optical properties parameters of cirrus.
