But there are also longitudinal waves, where the oscillations happen in the same direction as the wave is moving.

但是也有纵波，其中振荡发生在与波移动的方向相同的方向上。

The scientist who  captured this timelapse said that here, gravity waves were moving through an inversion, underneath  an elevated region of instability.

捕捉到这个延时摄影的科学家说，在这里，重力波正在一个高不稳定区域下方通过反转移动。

Meanwhile, that red might appear dull and muted if the wave is moving at a lower amplitude, but super bright if the wave has greater amplitude and thus higher intensity.

与此同时，如果波浪以较低的振幅移动，红色可能会显得暗淡无声，但如果波浪具有更大的振幅，因此强度更高，则红色会变得非常明亮。

So we can measure how high the wave is at every given instant and how fast the wave is moving across through the houses washing away the houses and across the street.

所以我们可以测量海浪在每个给定的时刻有多高，以及浪潮穿过房屋、冲走房屋、穿过街道的速度有多快。
