Particle velocity
From Glossary of Meteorology
particle velocity
In ocean wave studies, the instantaneous velocity of a water particle undergoing orbital motion.
It has the scalar value where T is the wave period, H the wave height, z the depth below still-water level, and L the wave length. At the crest, its direction is the same as the direction of progress of the wave; at the trough it is in the opposite direction.
