摘　　要：运用常规气象资料、逐时数字红外卫星云图及雷达回波资料，分析了１９９８年６月１８～１９日福建省闽北地区大暴雨过程的中尺度云团发生、发展等演变特征及湿斜压锋区和低空西南急流对中尺度对流云团发生发展的作用，揭示了大暴雨形成和发生的一些特点。By means of the conventional meteorological data,digitized infrared satellite imagery andthe radar echoes, the developing characteristics of the mesoscale convective cloud clusterswhich caused the cloudburst over the northern Fujian in 18 - 19 June 1998 were analysed,andthe effect of the wet-baroclinic front zone and the southwest jet flow in low altitude on themesoscale convective cloud clusters were discussed. Some features of cloudburst during thedeveloping were given.
