Radar loop of the tornado event. The top left image is base reflectivity (Z) and the top right image is storm-relative velocity (SRV). The bottom two images are correlation coefficient (CC) and spectrum width (SW). Low values of CC, combined with a SRV couplet or on a convergence zone, are a strong indicator of debris being lofted by a tornado. High values of SW can also denote the presence of a circulation.
