Two Mesocyclones Detected as One
The image below contains reflectivity at Swp 1 and then 5, and SRV data
at selected sweeps. The SRV data increases in height from top to
bottom and left to right. The point is to illustrate the existence of two
independent circulations which the current version of the MDA was unable
to separate. The blue, 2D shear segments are all labeled #14, meaning they
comprise one 3D mesocyclone. The higher elevation segments, beginning at
sweep 8, are the beginnings of a new mesocyclone aloft. However, the algorithm
associates this new mesocyclone with the one lieing below sweep 8. This
is both due to the proximity of the two circulations, and the fact that
the low elevation mesocyclone is not evident at sweep 8. With only one
2D candidate to choose from, the algorithm "thinks" it is the continuation
of the other mesocyclone.
