Progressive vector diagram.
(After Le Blond and Mysak
1978)
vector of the earlier time step. The succession of vectors forms a diagram
that represents the mean (--7Eulerian representation) movement for the time
series and its variations. The picture looks like a trajectory (--7Lagrangian representation), but is a representation of the velocity at one point.
progressive wave (or traveling wave) wave moving relative to the fluid and transporting energy in that direction. Progressive waves are usually considered
plane waves of a sinusoidal shape. They can be expressed mathematically by a
wave-number vector, pointing in the direction of propagation and with a
length equal to the wave number (--7wave characteristics). The counterpart of
progressive waves is standing waves, in which there is no phase propagation.
