以2009年14号台风“彩云”为例，基于CloudSat相关云产品统计了台风深对流云中水云和冰云的有效粒子半径、云水含量谱分布的特征。在此基础上探讨了两个云微物理参量的相关性，并对不同发展时期的多个台风进行了该关系的应用检验。研究结果表明，不论是水云还是冰云，若以云水含量为横坐标，以云有效粒子半径为纵坐标，台风深对流云像元散点图的分布存在明显的下边界线，且边界值随着有效粒子半径和云水含量参数值的增大而逐渐提高；零度层以下低层水云的有效粒子半径与液态水含量呈正相关关系，可采用对数关系式进行拟合。经检验，该拟合关系式对其他发展阶段的台风同样适用，证实了该关系的普适性。

Taking the typhoon "Choi-wan" on the 14th of 2009 as an example, based on CloudSat related cloud products, the effective particle radius and cloud water content distribution characteristics of water and ice clouds in the deep convection cloud of the typhoon were calculated. On this basis, the correlation between the two cloud microphysical parameters was discussed, and the application test of this relationship was performed for multiple typhoons in different development periods. The results show that, for both water clouds and ice clouds, if the water content of clouds is taken as the x-coordinate and the effective particle radius of clouds as the y-coordinate, the distribution of scatter map of the typhoon deep convective cloud pixel has an obvious lower boundary. The boundary value gradually increases with the increase of effective particle radius and cloud water content parameters. The effective particle radius of low-level water clouds below the zero layer has a positive correlation with the liquid water content, which can be fitted using a logarithmic relationship. The test shows that the fitting relationship is also applicable to typhoons in other stages of development, confirming the universality of the relationship.
