According to the authors, asperitas clouds are  defined by their rough, somewhat wavelike cloud base, that lacks the smooth undulating shape of  the (possibly related) undulatus cloud type.

根据作者的说法，阿斯佩里塔斯云是由其粗糙的、有点波状的云底来定义的，它缺乏（可能相关的）波状云类型的光滑起伏形状。

These aren't smooth and wavelike, like the undulatus cloud type we just looked at, but have  a formation that is chaotic, like the stormy ocean we talked about earlier.

这些云并不像我们刚刚看到的波状云那样光滑且呈波浪状，而是具有混乱的形态，就像我们之前讨论过的波涛汹涌的海洋。
