All right, maybe that’s a bit over-dramatic, but at least I got you still reading. I’ve discussed elsewhere<\/a> the sensitivity we’ve seen with low level AzShear and Rotation Tracks when it comes to surface features such as outflow boundaries or artifacts such ground clutter. Here we see sensitivity to what’s going on above – i.e., velocity data with a high reflectivity mesocyclone aloft being smeared downward with sidelobe contamination. To illustrate…<\/p>\n\n\n\n

So, it’s fairly evident that velocity is being contaminated down low. Unfortunately, this also affects the AzShear calculations…<\/p>\n

Just something else to be aware of…<\/p>\n
