根据EOS/MODIS多通道遥感数据,针对2006年6月30日20:00~2006年7月1日20:00安徽省北部出现的一次强降水,定性地分析了产生暴雨的强对流云团的特征,揭示了强对流降水云团的云系特征和结构特征,并用地面雨量观测资料开展验证分析。研究结果表明利用MODIS资料对安徽省暴雨的监测是行之有效的方法之一,MODIS云图的云反照率、云顶亮温、两通道反照率差值、云的相态、红外亮温比值、温湿度场的结构与云的降水强度有一致的对应关系,MODIS遥感资料对强对流云团的云特征具有很好的指示作用。
Based on EOS/MODIS multi-channel remote sensing data, the characteristics of a strong convective cloud were analysed qualitatively according to a heavy rainfall in the northern of Anhui province from 30, June to 1, July in 2006. The characteristics of the cloud system and structure of the strong convective cloud were shown. And the strong convective cloud was verified by the ground precipitation observation data. The results show that it is one of the effective methods to survey heavy rainfall based on MODIS data in Anhui province. The rainfall intensity accords with the cloud reflectivity, cloud top TBB, two channel reflectivity difference, cloud phase, infrared temperature ratio, temperature and humidity structure of the MODIS data. The characteristics of the strong convective cloud are indicated effectively based on the MODIS remote sensing data.
