RADAR-ECHO STRUCTURE OF A QUASI-STEADY HEAVY RAIN STORM
(Received 27 June, 1987 and in revised form 9 December, 1987)
Abstract
An isolated cumulonimbus cloud that produced 183 mm of heavy rainfall at Kasugai City was observed by the use of an X-band RHI radar. It lasted for 5 hours and showed no movement for 3 hours. It had quasi-steady structure, but showed pulsative behavior every 20 min. In general, this storm behaved similar to the way supercell storms behave in continental countries. Its unique characteristics of a remarkably low echo top (less than 8 km) and a weak gust front are attributable to the humid environment of Japan.
