摘　　要：基于多普勒天气雷达、区域气象观测站、常规观测和NCEP再分析数据等,利用三维雷达拼图技术对2018年第18号台风“温比亚”造成的山东暴雨中尺度特征进行分析。研究表明:台风“温比亚”造成的山东暴雨,不同阶段雨强特征有较大差异,长时间强降雨是造成灾害性暴雨的主要因素;此次台风暴雨雨团具有很强的移动特征,是否形成“列车效应”是造成灾害性暴雨的重要因素;雷达三维拼图数据可以清晰识别和分析暴雨过程中尺度雨团的移动、合并和发展规律,这些对准确监测预报暴雨的发生至关重要。In this paper,the mesoscale characteristics of rainstorms in Shandong caused by Typhoon RUMBIA in 2018 are analyzed by using 3-D radar mosaic technology based on data of Doppler weather radar,regional automatic meteorological station,conventional observation,and NCEP reanalysis.The results show that the rainstorms in Shandong caused by Typhoon RUMBIA have great differences in the characteristics of rain intensity at different stages,and the sustained heavy rainfall is a main factor causing the disastrous rainstorms;the rainstorm clusters of this typhoon have strong moving characteristics and the formation of train effect is an important factor causing the disastrous rainstorms;the 3-D radar mosaic data can clearly identify and analyze the movement,merging,and development of mesoscale rain clusters during rainstorms,which is very important for accurate monitoring and forecasting of rainstorms.
