摘　　要：根据2007年7～8月地基双通道微波辐射计、激光粒子探测仪和翻斗式自动雨量计的同步观测资料,采用对比分析和统计分析方法,建立了降水观测时段汽态水含量与液态水含量、汽态水含量与雨强、液态水含量与雨强的相关分析方程,且方程均通过了显著性检验;同时,验证了翻斗式雨量计每分钟观测数值与激光粒子探测仪反演的每分钟降水量有较好的一致性。提出了整层大气汽态水含量大于69mm和降水强度大于1mm·h-1时或液态水含量大于0.6mm和降水强度大于1mm·h-1时,云系具有人工增雨潜力,可用于指导人工增雨作业或降水天气预警。Correlation analysis equations about water vapor content and liquid water content,water vapor content and rainfall intensity,liquid water content and rainfall intensity were established according to the ground dual-channel microwave radiometer,laser particle detector and automatic tripper-hopper rain gauge dump synchronous observation data during July-August in 2007.The equations were based on the comparative analysis and statistical analysis methods and were significantly correlative.It was verified that automatic tripper-hopper rain gauge dump per minute observation values were consistent with per minute precipitation got by laser particle detector.The conclusion was that the cloud would have the potential of artificial rainfall when water vapor content in the atmospheric layer was higher than 69mm and precipitation intensity was greater than 1mm.h-1,or the liquid water content was bigger than 0.6mm and precipitation intensity was greater than 1mm.h-1,and it cloud be used in determining artificial rainfall or precipitation weather warning.
