Abstract: The Tianshan Mountains are an important source of water in Xinjiang, China. The analysis of vertical and horizontal distribution of cloud properties in macro and micro level can provide great significance to carry out artificial precipitation enhancement scientifically and efficiently. The cloud height, cloud thickness, ice particle equivalent radius/diameters(IER,IED), the water particle equivalent radius(LER), ice water content (IWC), liquid water content(LWC), ice water path(IWP) and liquid water path(LWP) for 3 heavy rainfalls processes in the Tianshan Mountains were analyzed by using CloudSat and Aqua satellite data(IER, IED). The results showed as follows:(1) The cloud of heavy rainfalls in the Tianshan Mountains area was in the range of 0.9-9.4 km, the cloud bottom was relative lower and the cloud was relative thicker in the eastern and western parts while the cloud bottom was relative higher and the cloud was relative thinner in the central area. Precipitation ratios for the central area, eastern and western parts were 5%, 5% and 15.6%, respectively.(2) The IER, LER, IWC and LWC for the cloud of heavy rainfalls were 0-60 μm, 0-5 μm, 0-50 mg·m^-3 and 0-50 mg·m^-3, respectively. In vertical direction, low vales of these micro physical properties of clouds were in a dominant position from lower layer to upper layer and unimodal distribution was observed in western part and the central area while peaks were appeared in the bottom and upper part of clouds for western and central area. At same time, bimodal distribution was observed for eastern part and the maximum value appeared in the bottom and upper of clouds.(3) IED of clouds of heavy rainfalls was smaller in the southern and western part while it was bigger in central area and eastern part. LER was larger in the central area while it was smaller in eastern, western and southern parts. IWP changed from larger to smaller according to the central area, eastern part, western part and southern part. The LWP value in central area was slightly bigger than that in the western and eastern part and it got the minimum value in the southern part.
