Abstract This paper analyzes the macro and micro characteristics of a summer topographic cloud precipitation in the Central Tianshan Mountains region based on observation data such as the C-band next-generation Doppler weather radar, Ka band cloud radar, light rain radar, and ground-based microwave radiometer.The research shows that the precipitation process is influenced by west wind airflow to produce topographic cloud precipitation.The height of the 0 ℃ layer during this precipitation process is around 4 km, and the atmospheric stratification exhibits a dry wet dry layer distribution.The radar reflectivity factor is mainly distributed in the range of 15～30 dBZ, with a cloud thickness of about 6 km.The particles inside the cloud rapidly increase under strong turbulence.At a height of 3.5 km, there is a significant broadening of the raindrop spectrum, with a continuous decrease in the concentration of small particles and a rapid increase in large particles.Based on the height information of the 0 ℃ layer, it can be concluded that particles above 3.5 km are mostly ice phase particles, while particles below 3.5 km are mainly liquid phase particles.Multiple radars with different wavelengths are suitable for measuring particles of different scales, allowing for comprehensive observation of the occurrence and evolution of precipitation clouds as a whole.Research helps to scientifically evaluate the potential of artificial precipitation enhancement and cloud seeding in the Baiyanggou area of the Central Tianshan Mountains from the perspective of macro and micro physical characteristics of terrain clouds.
