摘要： 为了研究呼伦贝尔市暴雨环流形势特征，防范暴雨引发的洪涝灾害对农业产生的影响，使用1971—2010年呼伦贝尔市16站降水资料和NCEP再分析资料，对发生暴雨过程天气环流背景进行分型。结果表明：呼伦贝尔市暴雨过程主要影响系统大致分为4类：（1）西太平洋副热带高压与西风带系统的相互作用（71个，43.3%）；（2）西太平洋副热带高压与其西侧北上的台风共同与中高纬度环流系统相互作用（35个，21.3%）；（3）台风或热带气旋与西风带系统远距离相互作用（27个，16.5%）；（4）西风带系统的直接作用（31个，18.9%）。

Abstract: In order to study the atmospheric circulation characteristics of rainstorm at 500 hPa in Hunlun Buir and to guard against the impact on agriculture from flood disasters caused by rainstorm, the atmospheric circulation background of the rainstorm cases were classified by utilizing the daily precipitation data of 16 stations and NCEP grid reanalysis data in Hulun Buir City between 1971 and 2010. The result showed that: the rainstorm cases were approximately classified into 4 types: (1) the direct interaction between subtropical high and westerlies zone system (71 cases,43.3%); (2) the long distance interaction between subtropical high and typhoon with westerlies zone system (35 cases,21.3%); (3) the long distance interaction between typhoon or tropical cyclone and westerlies zone system (27 cases,16.5%); (4) the directly action by westerly zone system (31 cases, 18.9%).
