潮解气溶胶的冻结是波浪云中冰粒子最可能的形成机制。类似的微物理过程也被假定为飞机尾迹的形成。在类似环境条件下形成的尾迹云和波状云中进行了气溶胶和云粒子的测量。使用MASP粒子探针的一些独特功能，即直接检测前向和后向散射光，以及测量粒子间距以确定与微物理过程相关的小尺度云结构，比较了这两种云的微物理和光学特性。数据表明，两种云的光学性质相似，但云粒子的数量浓度、液态水含量和空间组织存在显著差异。
The freezing of deliquesced aerosols is the most likely formation mechanism of ice particles in wave clouds. A similar microphysical process has been postulated for the formation of aircraft contrails. Aerosol and cloud particle measurements have been made in contrail and wave clouds that formed under similar environmental conditions. Microphysical and optical properties are compared for these two types of clouds using a number of unique capabilities of the MASP particle probe, i.e., direct detection of forward and backscattered light, and the measurement of particle spacing to determine small scale cloud structures relevant to microphysical processes. The data indicate similarities in optical properties, but significant differences in the number concentrations, liquid water contents and the spatial organization of the cloud particles in the two types of clouds.
