中文摘要:
      利用广东省阳江地区2010年7—8月WMO组织的国际高性能探空系统对比试验数据,对Vaisala RS92型探空仪和国产长峰探空仪的测云性能进行对比分析,并利用同步观测的Vaisala云高计和毫米波雷达数据进行了分析和验证。结果表明:两种探空仪判别的云层垂直结构都能较好地反映阳江的实际的云层情况。对于低云,两种探空仪的探测结果比较接近;对于不密实的云层,两种探空仪都会误判为多层云。长峰探空仪容易漏判云层,两种探空仪对于高云的判别效果均不理想。RS92探空仪探测的高云的云底和云顶的平均高度要高于长峰探空仪的探测结果。
英文摘要:
      Based on the intercomparison test data from high-quality radiosonde systems orgnized by WMO in Yangjiang, Guangdong from 12 July to 3 August 2010,the performance of Vaisala RS92 and Changfeng radiosonde on clouds vertical structure is analyzed, whose results are validated by ground-based remote sensing instruments(laser ceilometers and cloud radar) simultaneously. The measured results of these two instruments could reveal the actual cloud condition in Yangjiang, especially for the low-level clouds, while for the low-density cloud, both of these two kinds of radiosondes judged it for multi strstus; it is easy for Changfeng to miss cloud layer. The effect is not perfect for these two radiosondes in judging the high clouds. The results of the base and top height of high cloud by RS92 are averagely higher than those by Changfeng.
