內容簡介：
Contrary to the popular proverb that a million things are happening in the ocean, in reality, very few things occur in the oceans. In the oceans ( same in the atmosphere, which is also a fluid ), in the basic form, only three types of pure wave motion is possible. For longitudinal waves, which are also referred to as sound waves, acoustic waves and compressional- rarefaction waves, as the wave propagates in a horizontal direction, the particles move back and forth in the same horizontal direction. The second type are vertically transverse waves, in which, as the wave propagates in a horizontal direction, the particles move up and down in the direction of gravity. The third type of wave motion is the horizontally transverse wave, or the Rossby wave ( named after C.G. Rossby, who first discovered them ).
