Based on ERAinterim reanalysis data from 2009 to 2018, the spatial and temporal distribution characteristics of cloud liquid water content and cloud ice water content in Qinghai were analyzed. The results show that both cloud liquid water content and cloud ice water content increased from northwest to southeast. Cloud water resources were concentrated in the southern part of Yushu, southeastern part of Guoluo and Qilian mountain areas, where they were highest in summer and autumn and could reach 60～70 g·m-2. Cloud liquid water content and cloud ice water content increased firstly and then decreased with increasing altitude. Cloud liquid water content was concentrated at a height of 4 to 6 km, and cloud ice water content was concentrated at a height of 7 to 8 km. The altitude with the maximum cloud ice water content was higher than that with the maximum cloud liquid water content. In summer and autumn, the amplitudes of vertical variation of cloud liquid water content and cloud ice water content were biggest in Qinghai southern plateau, while they were smallest in Qaidam Basin. Cloud liquid water content and cloud ice water content in most parts of Qinghai increased from 2009 to 2018 and the increasing trend in autumn was most obvious. Cloud liquid water content and cloud ice water content was highest in September and lowest in January. The differences in monthly variations of cloud liquid water content and cloud ice water content in Qaidam Basin were smallest. The difference in monthly variations of cloud liquid water content in eastern agricultural region was biggest, while the difference in monthly variations of cloud ice water content in Qinghai southern plateau was biggest.
