Five misocyclones occurring along a narrow cold frontal rainband (NCFR) were detected by single, X-band Doppler radar at Yokosuka, Japan on April 20, 2006. Each of the misocyclones, which formed in succession in the core and gap regions of the meandering NCFR over a period of 30 minutes, had a short lifetime. Three of the five misocyclones generated near the surface and reached altitudes of up to 4km ASL. The diameters of the lower-level misocyclones increased with altitude and vorticity in the order of 10^<-2>s^<-1> was observed near the surface. Two of the five misocyclones had similar diameters and vorticity, and at more than 6km ASL. One of the observed misocyclones was related to the tornado in Fujisawa and as a non-supercell type tornado within the NCFR. This tornado-related misocyclone had the largest vorticity (5×10^<-2>s^<-1>) near the surface (300m ASL) and was characterized as having the reduced diameter below the cloud base, which is considered typical of a tornado.
