Interactive comment on “TPVTrack v1.0: A watershed segmentation and overlap correspondence method for tracking tropopause polar vortices” by Nicholas Szapiro and Steven Cavallo

In "TPVTrack v1.0: A watershed segmentation and overlap correspondence method for tracking tropopause polar vortices, " Szapiro and Cavallo present a new software framework for detecting and tracking tropopause polar vortices (TPVs). They qualitatively describe TPVs as persistent areas of high potential vorticity (positive and negative) occurring along the tropopause that are associated with the broader polar vortex. They describe two other TPV tracking methods and give overview of the various considerations involved in robustly detecting and tracking features like TPVs.
