【摘要】 对大连地区2003年以来多普勒雷达观测到的29个降雹个例雷达体扫资料进行了PUP软件计算,得到每个个例的回波强度、顶高、30 dBz强中心高度、强回波顶高和垂直积分液态水含量的主要雷达参数值,将冰雹(强对流)云分为单体、多单体和强(超级)单体雹云三类,并总结了防雹作业判据指标;对3种类型实例的多普勒雷达PPI和RHI雷达回波强度和速度场进行分析,总结了3种不同类型冰雹云实例的防雹作业概念模型;集成了最新防雹催化理论和研究成果,结合作业实践,研究和设计了大连市防雹作业技术方案,以期为雹云判别和防雹概念模型及作业提供参考依据。更多还原

【Abstract】 29 hail cases of Doppler radar data in Dalian during 2003-2009 are calculated and processed by PUP software,main parameters of several radars including echo intensity,echo top height,30 dBz center height,top height of the strong echo intensity and VIL etc are obtained,hail-clouds are divided into mono-cell hail-cloud,multi-cell hail-cloud and super-cell hail-cloud,and hail-cloud parameter indexes are summarized.By analyzing and researching on Doppler radar PPI and RHI echo intensity and velocity fields to three kinds of hail-cloud typical cases,hail-suppression operation conception models aimed at different kinds of hail-cloud are generalized.The latest hail-suppression catalytic theory study results and operation practice are integrated.Hail-suppression operation technique project of Dalian is researched and designed.Research in hail-cloud judgment,hail-suppression conception models and operation technique methods are the base and premises of scientific decision and operation.更多还原
