摘　　要：雷达资料的网格化及拼图在气象业务中有重要的意义。给出了雷达资料网格化及其拼图的原理和流程,在此基础上利用商丘、徐州、盐城雷达站资料对2009年6月3～4日发生在该地区的超级单体风暴的雷达资料进行网格化处理和3种方法拼图试验。结果表明,最大值法能够较好地反映单体的实际特征;作为一种新的雷达拼图应用形式,进行出了雷达回波的时间序列拼图,分析显示,时间序列拼图能够较好地表征超级单体风暴的发生、发展、移动路径,有助于研究中小尺度系统的结构、演变。Radar data gridding and cinrad mosaic has significance in meteorological service.Based on the principle,process of radar data gridding and cinrad mosaic,and by using data from Shangqiu,Xuzhou,Yancheng radar stations,the gridding treatment and cinrad mosaic test with three methods were carried out on radar data of super-cell storm from Jun.3 to 4 2009.The results showed that the maximum value method could better reflect the actual characteristics of monomer.As a new application of cinrad mosaic,a time series of radar echoe was obtained.The analysis indicated that time serials mosaic could better present characterization of super-cell storm occurrence,development and move path,which will be benefit for study on structure and evolution of small-scale system.
