Initially there are two weak mesocyclone detections associated with the cyclonic south flanks of each cell. You can tell this is a strongly sheared environment by downshear stretching of the cells. Velocity indicates elongated mirror image shear zones on each side of each updraft (like the rock in the stream).<\/p>\n<p>These are sneaky because they can be vertically correlated (since the shear with the obstacle flow is deep enough to show up in multiple cuts). I\u2019m impressed that there is a sanity check (neighborhood check?) in which the number of detections is limited. The panels to the right of the figure above show continued 2D shear with perhaps the beginning of a mesoscylone. Even if there was a well defined mesoanticyclone, the algorithm is not configured to catch the negative shear.<\/p>\n<p>-marfafront<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here is a case with splitting cells.
