Tornadoes often occur in Guangdong Province in China, which have brought heavy casualties and property losses in recent years. To detect and warn tornadoes, a dualpolarization Xband Doppler radar CINRAD/XD has been built in Foshan. In the afternoon of 4 October 2015, a significant tornado occurred near Foshan, at the tip of the hook echo of a mini supercell. High differential reflectivity 〖WTBX〗Z〖WTBZ〗HH, low 〖WTBX〗Z〖WTBZ〗DR, and low zerolag correlation coefficient have been detected associated with the tornado at low levels. Analysis shows that it is the tornadic debris signatures caused by lofted tornadic debris.
