Abstract

<p> X-band dual-polarization (multi-parameter) radars were used to observe a supercell storm that generated an F3 tornado in Ibaraki Prefecture, Japan on 6 May 2012. The observed data collected for this storm clearly exhibited the typical polarimetric features of a supercell storm, such as the <i>Z</i><sub>DR</sub> (differential reflectivity) arc, <i>Z</i><sub>DR</sub> column, and the <i>K</i><sub>DP</sub> (specific differential phase) column, as well as their time evolution. The <i>Z</i><sub>DR</sub> arc emerged at 10 to 15 min before the tornadogenesis. The <i>Z</i><sub>DR</sub> column appeared approximately 1 h before the formation of the <i>Z</i><sub>DR</sub> arc and was intermittent until tornadogenesis. As the <i>Z</i><sub>DR</sub> arc appeared, the column became tall and stable and lasted until the dissipation of the tornado. These <i>Z</i><sub>DR</sub> signatures of the supercell storm persisted for approximately half an hour.</p>
