Initial Observation found during Test Case

Today’s archived training case starts us off with an already fairly active (and wet) broken line of storms dragging through Georgia.  As I’m getting acclimated with looking at Az Shear and TORP, I found an interesting drop out of data. While using KJGX radar, TORP was tracking a mesocyclone for a few frames before dropping out as said mesocyclone continued to approach the radar site. The mesocyclone did not seem to lose intensity or be cycling, so I was confused by TORP’s sudden disinterest.

I was then reminded that other radars may be reporting “closer” TORP objects. So I flicked on the ability to see TORP objects from multiple radars and low and behold, several objects were still tracking the meso.

Az Shear couplet with TORP objects from other radars, not KJGX where the Az Shear data is from.

The probabilities of these TORP objects were rather high with values of 64%, 68%, and 80%. I’m still a little confused on why one of these is read as closer than the actual closest radar of KJGX, but it did give me an idea. It would be neat to allow a sort of threshold limit to TORP objects from other radars to pop in when at a high enough probability so you have less but more potent objects on screen.
