Abstract :
Ku-band broadband radar is a short-range (15 or 20 km) high-resolution (range and temporal resolution of several meters and 1 min per volume scan with 30 elevations) weather radar to resolve fine structures of precipitation from the near surface (several tens of meters), and a networked observation with several Ku-BBRs covers the troposphere accurately and efficiently. In this paper, two latest observation results of the Ku-BBR and the Ku-BBR network are described. One is an observation of a small-scale tornado in Shonai airport by single radar, in which a fine structure of the small tornado is resolved in 4-D. The other is preliminary results of a networked observation with three Ku-BBRs in north Osaka area, in which fine structures of precipitation are resolved simultaneously and multi-directionally.
