Abstract:
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 dualpolarization Xband 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 zerolag 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.
