It's gonna be about a five inch significant wave height, which if we were to scale it up for this model would be 20 foot waves.
有效波高约为 5 英寸，如果我们将其放大到该模型，则有效波高将达到 20 英尺。

海平面
海平面是海水的平均高度。它是通过与标准平面的高度比较来确定的，然而由于牵涉到一些复杂且困难的测量，使得精确确定海平面成为一个困难的工作。
测量海平面的仪器叫做验潮仪，一般微风所导致的海面的波浪可以通过平均的方法消除掉，潮汐所导致的海平面的升高和跌落也可以通过长时间的观测后取平均值的方法消除掉。海平面的测量总是相对于陆地的测量，因此海平面的变化可以是真正地由于海面的变化导致的，也可以是由于陆地的变化导致的。

Significant wave height 平均海水面
In physical oceanography, the significant wave height (SWH or Hs) is defined traditionally as the mean wave height (trough to crest) of the highest third of the waves (H1/3). Nowadays it is usually defined as four times the standard deviation of the surface elevation – or equivalently as four times the square root of the zeroth-order moment (area) of the wave spectrum. The symbol Hm0 is usually used for that latter definition. The significant wave height may thus refer to Hm0 or H1/3; the difference in magnitude between the two definitions is only a few percent.
