The Ya'an area has a typical "windward slope" and "trumpet" topography， the observation and study of cloud-precipitation in the Ya'an area has always been one of the hot issues of mountain meteorology in China.In this paper， using the observation data of Ka-band millimeter-wave cloud radar， K-band micro-rain radar and DSG4 laser raindrop spectrometer during the autumn rainy season in Ya'an area in 2023， the two types of cloud-precipitation in Ya'an during the autumn rainy period are studied and compared.The results show that （1） the frequency of warm cloud-precipitation （WCP） is higher than that of cold cloud-precipitation （CCP） during the autumn rainy period in Ya'an， but the intensity of precipitation is generally weaker and the cumulative rainfall is less.（2） In terms of vertical structure and macroscopic features， there are obvious differences between WCP and CCP： the radar echo reflectivity factor Z high-frequency region of CCP has a wider distribution and stronger echo， and the magnitude of the slope of Z high-frequency region at different heights reflects the difference between the ice-phase particles' growth mechanism and rate and that of WCP's liquid cloud raindrops' touch-and-go growth rate； CCP's linear depolarization ratio， LDR， increases abruptly near the zero-degree layer due to the melting of ice-phase particles.The mean Doppler velocity Vm has a smaller value in the high-frequency region and the velocity spectral width W has a larger value in the high-frequency region， suggesting a larger mean droplet scale and a wider concentration distribution.In terms of macroscopic parameters， the cloud base and cloud top of the CCP are significantly higher， the cloud layer is thicker， and the distribution of values is more dispersed.（3） In terms of microscopic characteristics， the raindrop spectra of the two types of cloud-precipitation are different with altitude： the concentration of small raindrops in the CCP increases and then decreases with decreasing altitude due to the melting of ice-phase particles and raindrops merging， whereas that in the WCP fluctuates due to the effects of evaporation， merging， water vapor transport， and updraft lifting altitude.The medium- and large-sized raindrop concentrations of both types of cloud-precipitation increase with decreasing altitude on the whole.In terms of the differences in raindrop concentrations at different heights， above 455 m， the concentration of raindrops of all grain sizes in WCP is almost lower than that in CCP； below 455 m， the concentration of small and large raindrops in WCP is higher than that in CCP， and the concentration of medium raindrops is lower.（4） Comparison of the raindrop spectra under different precipitation intensities showed that when the precipitation is weak， the WCP had lower concentrations of raindrops of all particle sizes than the CCP， but when the precipitation reached a certain intensity （rainfall intensity R ≥5 mm·h-1）， the WCP produced more small raindrops and a small number of larger raindrops.The few extreme values of Z， LDR， Vm and W of WCP are larger than those of CCP at altitudes below 3 km due to the synergistic effect of low-altitude rapids and topographic uplift in the region， which makes the small WCP raindrops repeatedly touch and form medium-to-large raindrops in the re-uplift airflow.
