中文摘要: 使用液态二氧化碳(LC)对过冷层状云进行催化后,通过飞机粒子测量系统,GPS定位以及地面测雨雷达和地面雨强研究了催化前后云微物理参数的变化,揭示了部分因催化后产生的物理效应,特别是雷达RHI上2 5dBz回波在负温区出现较对称的凸起尖峰,可能是小冰晶的凝华增长释放潜热而引起的动力抬升所致。得出了催化有效的结论。
中文关键词: 液态二氧化碳，播云，凝华增长
Abstract:After catalyzing undercooling clouds with liquid carbon dioxide (LC), the change of microphysical parameters is analyzed by airplane particle measuring system, GPS orientation and ground radar. The results indicated that the phenomena, especially the heaving symmetrical peaks in negative temperature range observed in the 25dBz echo of radar RHI, was caused by the dynamical lifting of the coagulating growth of small ice with the latent heat releasing.
