摘　　要：为验证大型无人机在高原地区进行人工影响天气作业和飞行观测的可行性,也为研究高原地区的云降水特征和人工增雪作业效果,2022年四川省人工影响天气办公室联合中航(成都)无人机系统股份有限公司在青藏高原东侧(川西高原)开展多个架次人工增雪试验,并利用卫星资料和常规气象观测资料对2022年2月11-12日在青藏高原东侧开展的2架次人工增雪试验进行分析。结果表明:2022年2月青藏高原东侧人工增雪试验目标云的云底温度低于-10℃,云底粒子半径较大,云底粒子有效半径为31μm,云顶粒子有效半径为15~20μm。无降水云和降水云的云顶均发生冰晶化,在云顶存在冰晶粒子递减带,无降水云的冰晶化高度低于降水云,无降水云的冰化高度为-22℃,降水云的冰化高度为-29℃。In 2022,Weather Modification Office of Sichuan Province and AVIC(Chengdu)UAS Co.,Ltd.carried out several flights of artificial snow enhancement experiments on the eastern side of the Tibet Plateau,which has verified the feasibility of large-scale UAVs for artificial weather modification operation and flight observation on the Tibet Plateau,and has also provided a new effective way to study the characteristics of cloud precipitation and the effect of artificial snow enhancement on the Tibet Plateau.In this paper,two artificial snow enhancement experimental flights carried out on the eastern side of the Tibet Plateau on February 11-12,2022 were analyzed.Based on satellite data and routine meteorological observation data,the experimental flights were analyzed.The results show as following:On the eastern side of the Tibetan Plateau in February 2022,the temperature of the cloud bottom of the target clouds of the artificial snow enhancement experiment is lower than-10 C.The radius of cloud bottom particles is large,the effective radius of cloud bottom particles is 31μm,and the effective radius of cloud top particles are 15-20μm.Ice crystallization has occurred in the cloud tops of both non-precipitating and precipitating clouds.In the tops there are decreasing bands of ice crystal particles.The height of ice crystallization in non-precipitating clouds is lower than in precipitating clouds.The icing altitude is-22℃for non-precipitating clouds and-29℃for precipitating clouds.
