# Vertical velocity and areas undergoing active breaking
Figure 5: Vertical velocities and areas undergoing active breaking, computed using a simple model.

##W.mat
These files contain the vertical velocities, in a corrdinate system rotated by 20 degrees around Point Sal.

##Breaking.mat
These files contain the nondimensional quantity, U/c − 1>0, where U is the mean surface velocity of the internal 
wave relative to the outside area, and c is the speed of propagation. See the associated paper for more details
This quantity is used to determine areas undergoing active breaking, in a corrdinate system rotated by 20 degrees 
around Point Sal.
