摘要： 将1951—2011年吉林省主汛期降水量排名的前、后6位分别定义为多、少雨年，利用NCEP（2.5°×2.5°）再分析资料计算主汛期平均高度场、温度场、风场及比湿、涡度等物理量场；根据天气学原理和常规天气预报经验，对比分析主汛期典型多雨与少雨天气系统结构形态、分布位置、中心强度等特征。结果表明：500 hPa多雨年568等高线较少雨年平均偏南3个纬度，副热带高压588等高线较少雨年平均偏西7个经度偏北1个纬度；低层辐合高层辐散是多雨年的重要特征；850 hPa和700 hPa平均水汽含量多雨年明显多于少雨年；典型多雨年850 hPa风场贝加尔湖附近为单辐合中心，少雨年为双辐合中心。

Abstract: The precipitation during main flood season was rankedin a manner that the first and last six orders were defined as rainy years and rainless years respectively. Based on the NECP reanalysis data with resolution of 2.5°× 2.5°, a series of physical quantities such as the average height field, temperature field, the wind field, specific humidity and vorticity during flood season were analyzed. The structure and location as well as center intensity of synoptic system during flood season of rainy years and rainless years were compared according to synoptic theory and the conventional forecasting experience. The results indicate that compared with rainless years, the location of 568 isoheight at 500 hPa in rainy years is moved to the south about three latitudes, while high subtropical 588 isoheight is moved to the west about seven longitudes and to the north about one latitude. The lower convergence and upper divergence are the main features in a rainy year. The mean water vapor contents at 850 hPa and 700 hPa are higher in a rainy year than in a rainless year. The wind field near the Lake Baikal is a single convergent center in a typical rainy year at 850 hPa, while it is double convergent centers in a typical rainless year.
