Abstract: This paper studies perturbation in the precipitation microstructure. The main work here includes three aspects. First, raindrops velocity distribution under wind perturbation is shown. Then, simulation results of doppler-polarimetric spectrum with different intensity of turbulence are demonstrated. Furthermore, the relationship between the simulated doppler-polarimetric parameters and turbulence intensity is analyzed. The simulating results exhibited in this paper will give a help to understand turbulized meteorological objects.
