Study of the Rain Enhancement Operation Using a Small and Medium-sized UAV and Physical Responses
摘要
Abstract
This study analyzes a field experiment of artificial precipitation enhancement using a small and medium-sized UAV,conducted in the Bayinbuluke alpine grassland on July 9,2023.Ground precipitation data,FY-4A satellite observations,and raindrop spectrometer measurements were combined with the WRF mesoscale numerical model and the CA-FCM method to evaluate the operational effectiveness through physical verification,statistical testing,and numerical simulation.The results indicate that precipitation enhancement exhibited a cumulative effect with increased seeding frequency.Physical tests and numerical simulations showed consistent trends:precipitation was observed 60 minutes after the first seeding operation,while the response time for the subsequent three operations was shortened by 50 minutes.The maximum hourly rainfall intensities for the four flights increased progressively,measuring 1.036,1.998,2.165,and 3.502 mm·h-1,respectively.According to the CA-FCM statistical test,the average absolute precipitation enhancement in the total affected area after four seeding operations was 0.782×105 m³,with an average relative enhancement rate of 4.4%.The WRF numerical simulation yielded similar results,showing a precipitation increase of 0.738×105 m³ in the affected area 180 minutes after seeding operation,with an average enhancement rate of 4.3.The consistency among the three methods demonstrates the effectiveness of the UAV-based rain enhancement operation.关键词
