One is orography, which is the wavelike movement caused by  the flow of air over mountainous terrain.

一是地形，即山区上空气流引起的波浪状运动。

And as I start through the opening, I feel the pressure around me, propelling me in violent wavelike motions toward the mouth of the cave.

而且，我开始走向洞口时，感觉到来自四周的压力，就像汹涌的波涛，不断把我推向洞穴的开口。

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。
