AB: In Japan, heavy rainfalls originate from "stationary front" or "typhoon". In particular, typhoon plays an important role in the enhancement of stationary front and, subsequently, the occurrence of heavy rainfalls due to the supply of ample moisture. Therefore, paying attention to the movement and location of typhoon No.0613 in 2006, this study investigates the features of heavy rainfalls that occurred in northern Kyushu located in the west of Japan. In this event, 20mm/hr or more rainfalls were recorded in all AMeDAS observation points and, consequently, more than ten persons were died and missing due to the landslide disaster. Three peaks of rainfalls were closely related to the location of the typhoon. The first and second peaks were 94mm/hr (0600 to 0700JST) and 91mm/hr (0900 to 1000JST), respectively. These peaks were caused by the enhancement of the stationary front by southern wind (containing ample water vapor) that originates from the typhoon No.0613, which was 2,000km or more, far away from northern Kyushu. On the other hand, the third peak, 72mm/hr (1500 to 1600 JST), was caused by the direct effect of typhoon No.0613, which landed at 1800JST around Sasebo in northern Kyushu. It is necessary to note "disastrous local heavy rainfalls occur, even if a typhoon is 2000km or more, far away from heavy rainfall area, under the influence of the stationary front."
