Here’s a quick, classic example of where meteorological situational awareness plays a large role in storm interrogation while using the NTDA/NMDA algorithms. A first look at Base Reflectivity shows higher probabilities of NTDA/NMDA at a position of the supercell well detached from where you would commonly expect strong, deep rotation (notice the BWER also in the top left, cool!).
Sure enough, looking at SRM confirms messy and anomalous values of SRM likely associated with the back end of a boundary or front. Another example of anomalous values from both algorithms and how situational awareness can avoid miss identifying aspects of a supercell.
