摘要
对大连地区2003—2008年多普勒雷达观测到的37个冰雹和强雷雨个例雷达体扫资料进行PUP软件计算和处理,得到了每个个例雷达回波强度、回波顶高、30 dBz强回波中心高度、强回波顶高和垂直积分液态水含量几个主要雷达参数值、以及各参数随时间的变化特征,总结了冰雹云识别的雷达技术指标模型;根据大连地区降雹特点,将冰雹云分为强(超级单体)雹云、多单体雹云和单体雹云三类,总结了冰雹云类型判别的雷达指标(即防雹作业决策指标)。
The Doppler radar data of 37 hail and thunderstorm cases in Dalian during 2003—2008 were calculated and processed by PUP softwares,several radar main parameters including echo intensity,echo top height,30 dBz echo center height,top height of strong echo intensity VIL etc.and their temporal variations were obtained.Technique index models of hail-cloud identification were summarized.Based on hail characteristics in Dalian,the hail-clouds were divided into three types：cell,multi-cell and super-cell,and types of hail-cloud radar indexes were summarized（namely hail-suppression decision indexes）.By integrating the latest hail-suppression catalytic techniques and practical experience,the Dalian artificial hail-suppression operation models（operation technique projects）were studied and designed.The research did some basic work on hail-cloud identification,hail-suppression scientific decision and operation,and greatly improved the scientific level and economic benefit on Dalian artificial hail-suppression operation.
