A method and device for inverting a phase change process of water vapors in cloud based on a ground-based microwave radiometer are provided. The method includes obtaining the actually measured data ofa vertical detection target area of the ground-based microwave radiometer and checking data consistency; using the actually measured data and a cloud threshold to identify a mixed phase state cloud region and to calculate an air pressure profile; using the actually measured data in combination with the calculated air pressure profile, calculating each water vapor pressure profile in the cloud; and inverting the phase change process of water vapors in cloud by using a water vapor phase change model. The method solves a problem that it is difficult for a conventional dual-polarization radar toaccurately recognize a particle phase state due to a low signal-to-noise ratio and a satellite can only recognize the phase states of the water cloud and the ice cloud on to top of the cloud, and canobtain the phase change process with time and space of water vapors in the mixed phase cloud of the target region, reflects the dynamic trends of the balance between the solid, liquid, and gaseous states of water vapors in the cloud, is particularly applicable to predicting and forecasting rainfall phase states, analyzing the evolution characteristics of cloud microphysics, and determining artificial precipitation (hail prevention) cloud seeding positions and selecting right time for the job.
