摘　　要：利用测站雨量、加密区域自动站雨量、高空探测、卫星云图等资料,分析诱发顺昌"6.18"特大滑坡、崩塌、泥石流、地面塌陷等地质灾害的气象成因。结果表明,除地质地貌自然原因和人为因素外,与罕见连续特强降水天气过程的前期气候背景有关的是高空槽区稳定、中低层切变维持、高低空急流存在、中尺度系统强烈发展、充沛水汽输送辐合等气象条件导致特大暴雨引发地质灾害。Using informations such as the station rainfall, AWS rainfall of enciphered area, aerological ascent and satellite cloud picture, analyse meteorological contributing factors for the geological hazard which induced Shunchang ＂ 6.18＂ especially big geological disaster＇s landslide, avalanche, mud-rock flow, fall of ground meteorological origins and so on. The result indicated that besides geologicy of natural factors and human factors, what with rare continuously extra-heavy precipitation synoptic process preliminary climate background related was the upper-level trough area stable, the underlying bed shear maintenance, high low altitude jet stream meteorological conditions and so on existence, mesoscale system intense development, abundant water-vapor transfer convergence causes the especially big rainstorm to initiate the geological disaster.
