Polarimetric radar variables offer the possibility to improve upon existing statistically based cessation algorithms through the inclusion of physically meaningful trends reflecting interactions between in-cloud electric fields and microphysics. While previous studies have investigated the pairing of temperature/height and reflectivity thresholds, this study is based on decades of polarimetric radar research which has shown that propagation differential phase can be used to determine the presence of distinct phase and ice crystal alignment signatures in the presence of strong electric fields associated with lightning. This study determines the extent these ice-crystal alignment signatures (determined from polarimetric data) can be used to nowcast the cessation of lightning activity within a given thunderstorm. These results are compared to the Volume Averaged height Integrated Radar Reflectivity (VAHIRR) algorithm which was originally developed during the Airborne Field Mill II research project and utilizes horizontal reflectivity as a baseline to determine if the addition of polarimetric radar data shows improvement to the prediction of lightning cessation. A summary of results and a discussion of the feasibility of an operational algorithm will be presented.
