What percentage of water molecules are moving more horizontally than
vertically for what percentage of the time? That percentage is
certainly pretty small. Even for those normal steady-state waves, it
appears that the vertical motion at the surface is still greater than
the horizontal motion for at least half of the cycle. *Anywhere except
at the very surface, the vertical motion is obviously greater than the
horizontal motion*. But the subject was a transient tsunami wave where
the horizontal motion is virtually non-existent because of inertia.
Thanks for the example that proves my point.
