Three Properly Detected Vortices
Here the MDA distinguishes between 3 closely spaced vortices. At (01:06)
the MDA encountered a problem when the top of one vortex coincided with
the bottom of another; the algorithm combined the two. Now at (01:16) there
are 3 vortices in the data. This time, however, they are nearly identical
in depth, somewhat relieving the vertical association problem. The MDA
identifies two of the vortices as mesocyclones, and discards the third
because it is too weak.
