Main results are as follows. (1) On 2 July 1995, long-lasting line-shaped rain echoes were observed by our RHI and marine radars. These echoes existed over the same ragion from Higashi-Nagasaki to the NE. direction of Isahaya and Konagai area. (2) These echoes consisted of small convective echoes which moved from SW to NE.. The direction of the line agreed with the direction of the movement of individual echoes and with upper wind conditions. (3) The features of these rain echoes and the weather conditions are strongly suggesting the topographical enchancement of rain formation by a deep valley at the Nagasaki Peninsula., 長崎大学教育学部自然科学研究報告. vol.55, p.9-22; 1996}, pages = {9--22}, title = {長崎市東部から諫早市方面に伸びるライン状降雨エコーの解析と地形効果に関する考察}, volume = {55}, year = {1996} }
