Highest Ocean Waves

最高海浪

According to Ned Mayo (see Ref), the highest reliably measured ocean waves were reported by officers of the Navy oiler USS Ramapo in the North Pacific on February 7, 1933. By triangulation on the ship's superstructure, they measured a wave height of 34 meters (112 feet) peak to trough. The period of the wave was 14.8 seconds and its wavelength was calculated to be 342 meters. Using the wave velocity expression for this wavelength in the deep water limit, the wave speed is calculated to be 23 m/s. Mayo calculates the power of one meter length of such a wavefront to be 17,000 kilowatts!

根据Ned Mayo（见参考文献），1933年2月7日，美国海军油船USS Ramapo的船员报告了目前可靠测量到的最高海浪。他们通过船体上层建筑的三角测量法，测得波高为34米（112英尺）峰谷间。该波的周期为14.8秒，其波长计算为342米。利用深水区极限下该波长的波速表达式，计算出波速为23 m/s。Mayo计算出这种波前中1米长度的波的功率为17,000千瓦！

The crew of the Ramapo measured these waves and lived to tell about it because their relatively short ship(146 m =478 ft) rode these very long wavelength ocean mountains without severe stresses on the craft. Mayo expresses concern about the safety of some modern giant ships (>250 meter length) in such seas.

Ramapo号船员测量了这些波浪，并得以幸存讲述此事，因为他们的船相对较短（146米=478英尺），能够轻松地在这些非常长波长的海洋山峰上航行，而船体并未受到严重应力。Mayo对一些现代大型船只（长度>250米）在这样的海况下的安全性表示担忧。

The USS Ramapo in Mountainous Waves

山脊波中的 USS Ramapo
In February, 1933, the USS Ramapo, a 146 meter (478 ft) Navy oiler found itself in an extraordinary storm on its way from Manila to San Diego. The storm lasted 7 days and stretched from the coast of Asia to New York, producing strong winds over thousands of miles of unobstructed ocean. Driven from behind by winds on the order of 60 knots, the crew had time to carefully observe the nearly sinusoidal mountainous waves. An officer on the deck observed the crest of the wave approaching from behind just over the level of the crow's nest while the stern of the ship was at the trough of the wave. Subsequent scaling yielded the height of 34 meters for the wave.
1933年2月，军舰“拉马波号”（USS Ramapo）在从马尼拉前往圣地亚哥的途中，遭遇了一场异常的风暴。该风暴持续了7天，从亚洲海岸延伸至纽约，产生了数千英里无遮挡海域上的强风。受每小时60海里左右的风从后方推动，船员有时间仔细观察那些近似正弦波的山状波浪。一名军官在甲板上观察到，波浪的峰顶从后方接近，刚好超过电平的海鸥巢高度，而船尾则处于波浪的谷底。后续测量得出波浪的高度为34米。

Velocity of Idealized Ocean Waves

理想化海洋波的速度

The velocity of idealized traveling waves on the ocean is wavelength dependent and for shallow enough depths, it also depends upon the depth of the water. The wave speed is

理想化海洋中传播的行波速度取决于波长，并且在水深足够浅的情况下，还取决于水深。波速是

In deep water, the hyperbolic tangent in the expression approaches 1, so the first term in the square root determines the deep water speed. The limits on the tanh function are

在深水区，表达式中的双曲正切接近1，因此平方根中的第一项决定了深水速度。双曲正切函数的极限为

so the limiting cases for the velocity expression are

因此，速度表达式的极限情况是
For a wavelength of m and a depth of m,
the wave speed is m/s
compared to the deep water limit speed of m/s,
and the shallow water limit speed of m/s

While this wave speed calculation may be a good approximation of the experimental wave speed, it cannot be depended upon as a precise description of the speed. It presumes an ideal fluid, level bottom, idealized waveshape, etc. It is also the speed of a progressive wave with respect to the liquid and therefore does not include any current speed of the water. In technical literature, this speed with respect to the liquid is called the "celerity" of the wave.

尽管这种波速计算可能很好地近似了实验测得的波速，但它不能作为波速的精确描述。该计算假设为理想流体、水平底面、理想化的波形等。它也是相对于液体的波速，因此不包括水的流动速度。在技术文献中，这种相对于液体的波速被称为‘波速’。
