Abstract: A preliminary survey of clear-air echo appearances over the Kanto plain in Japan from July to December 1997 is presented. A distinct contrast was seen between clear-air echoes observed over land and their absence over the ...

Abstract: his paper reports a high-speed volumetric observation of a wet microburst event using X-band phased array weather radar (PAWR) in Japan. On 10 September 2014, PAWR observed the three-dimensional structure of a convection ...

Abstract: On 25 February 1999, on the western side of the central mountain range of Japan, orographic snow clouds had formed under conditions of weak cold advection due to a winter monsoon after a cyclonic storm. The data from Ka-band ...

Abstract: Optical and microphysical properties of the upper clouds at an altitude range of 5?11 km were measured over Tsukuba, Japan, on 29?30 March 2004 using a ground-based Raman lidar and a balloon-borne hydrometeor videosonde ...

Abstract: On 25 February 1999, due to a winter monsoon after a cyclonic storm, orographic snow clouds formed under conditions of weak cold advection on the western side of the central mountain range of Japan. In this study, the ...

Abstract: three-dimensional (3D) winter lightning mapping system employing very high frequency (VHF) broadband signals was developed for continuous remote observation in winter. VHF broadband pulses radiated by leader progression ...

Abstract: Life histories of low-level misocyclones, one of which corresponded to a tornado vortex within a winter storm in the Japan Sea coastal region on 1 December 2007, were observed from close range by X-band Doppler radar of ...
