摘  要:
利用2009—2015年广西11—12月地面、高空气象观测资料及飞机人工增雨作业宏观记录进行统计分析,对增雨作业天气系统进行分型,并分析相应作业云系,建立增雨作业天气概念模型,利用模型分析一次增雨作业个例。结果表明,广西11—12月增雨作业天气系统主要有5类,包括冷空气型、高空槽型、华南静止锋型、低层南风急流型、台风型;其中冷空气型是最典型的降水天气形势。作业云系以层状云为主,有少量层积混合云,主要包括层积云、层云、积云、高层云,基本为暖云结构。层状云中下部可开展飞机作业或利用地面烟炉进行暖云催化作业,层积混合云中积状云部分可开展地面火箭作业。

摘  要:
Using the surface meteorological observation data,sounding data and the operation information of aircraft artificial precipitation enhancement in November and December from 2009 to 2015 in Guangxi,we classified these precipitation weather systems,took an analysis of relative cloud systems,and developed conceptual synoptic models of precipitation enhancement operation based on which an aircraft artificial enhancement process was studied. The results indicated that these precipitation weather systems could be summarized into five types of cold air,upper trough,stationary front of southern China,southerly stream,typhoon. Among these patterns,the cold air pattern was the most typical precipitation weather situation. The relative cloud systems( including Sc,St,Cu,As) gave priority to the stratiform warm cloud,while including less stratocumulus mix cloud. The middle and lower part of stratiform cloud was suitable for aircraft and surface furnace artificial precipitation enhancement. The cumulative cloud be used to carry out ground rocket operations.
