应用雷达回波检验人工增雨效果的个例分析 总被引:1,自引:0,他引:1
利用713-C型雷达对1次飞机增雨过程进行了跟踪探测,发现有利于人工催化的云区(20dBz),经过人工催化作业后回波增强到30dBz并产生增雨。也有一部分云区(小于20dBz)虽然也进行了人工催化,但无明显增雨效果。 相似文献

16 aircraft missions were conducted for the measurement of atmospheric aerosols in separatedays of late spring and early summer of 1996 and 1997.The paper deals with detailed analysis ofthe variation in vertical/horizontal distributions of the concentration of the particles and their sizedistribution at 0—5 km above ground,and with the relations to temperature and relative humiditydocumented in general.Evidence suggests that the concentrations show different distributionfeatures in vertical above and below the cap of the mixed layer:the particle size distribution issubject to a range of forming mechanisms,displaying a multi-modal pattern:the horizontalconcentration experiences remarkable variation:temperature and relative humidity stratificationshave conspicuous influence on the concentration and size distribution of aerosols. 相似文献
