中文摘要: 采用大型无人机开展人工增雨作业具有较好的应用前景。利用2020年10月27日大型无人机试验资料，分析了无人机作业性能及人工增雨微物理参量变化特征。结果表明：无人机操控灵活，具备较好的防除冰和抗侧风能力，作业、探测时长达5 h以上，可在大范围开展人工增雨及探测工作。催化作业后水平探测的云粒子微物理量呈现出浓度和直径增加的特征，低层粒子浓度明显高于高层；催化前后云微物理特征的变化与选取的云体位置及时间有很大关系。在催化作业结束后20～30 min 内，地面降水现象仪中雨滴数浓度先减小后增大，而粒子有效直径持续增加；受催化影响,云粒子谱呈现大云粒子增加、降水粒子谱拓宽的特征。

Abstract:With the data of daily outpatient visits of allergic rhinitis, air pollution and meteorological data in the three cities of Lanzhou (2014-2016), Tianshui (2016-2018) and Zhangye (2016-2018), this study analyzes the relationship between relative humidity (RH), absolute humidity (AH) and the daily outpatient visits of allergic rhinitis. In the three cities, the peak period of daily outpatient visits for allergic rhinitis is from August to September. The decrease in RH could lead to significant increase in outpatient visits for allergic rhinitis in the three cities. With the each 1% decrease of RH, the outpatients visit for allergic rhinitis in Lanzhou, Tianshui and Zhangye could increase by 1.36%, 2.30% and 1.50%, respectively, while the outpatients visit for allergic rhinities in the three cities have the increase of 14.92%, 16.00% and 13.98% accordingly for each 1 g·m-3 decrease in AH. Our study suggests that the onset of allergic rhinitis is negatively associated with atmospheric environmental humidity, and the dry and low humidity environment is an important risk factor for allergic rhinitis in arid area. Compared with RH, AH could better reflect the effect of environmental humidity on allergic rhinitis
