摘要
用Micaps实时资料、CPAS卫星反演分析资料、NCEP再分析资料、ECMWF再分析资料,多普勒雷达PUP产品资料,对2015年12月1日夜间至2日凌晨沈阳地区罕见冬季降雨过程,进行了天气学分析、及大气微物理人工增雨作业条件分析,并结合沈阳地区人工增雨作业指标,得出本次降雨过程在厄尔尼诺正在发生的背景下,为常见的高空槽转东北冷涡型,水汽、动力等微物理作业条件也适合于开展人工增雨作业,并给出了相应的作业指导参数,为沈阳地区今后在冬季降雨天气过程中开展人工增雨作业积累了宝贵经验。
In this paper,synoptic analysis and analysis of atmospheric microphysical rainfall enhancement conditions were conducted for the rare winter rainfall process occurring in the Shenyang region from the night of December 1 to the early morning of December 2,2015,using the Micaps real-time data,CPAS satellite inversion analysis data,NCEP reanalysis data,ECMWF reanalysis and Doppler radar PUP product data. It was concluded from the analysis,with the rainfall enhancement operation indices in this region being taken into account,that the rainfall weather process at this round was suitable for rainfall enhancement operation. In addition,corresponding operation instruction parameters were achieved,which provided references tofuture rainfall enhancement operations under winter rainfall weather conditions in Shenyang region.
