Based on the raindrop size distribution (RSD) data observed with PARSIVEL disdrometers deployed at different altitudes on Mt. Huang from June to July 2011, several microphysical parameters and the Gamma function fitting to raindrop spectra as well as the falling velocity of raindrops at different altitudes for different rain types (stratiform and convective) were compared and analyzed. Results show that convective precipitation had higher rainwater content, more intense rainfall rate, larger raindrops and higher raindrop concentrations compared with the stratiform precipitation at the same height; for both convective and stratiform precipitation, the diameter of raindrops on the mountainside was larger than that in the mountaintop and mountain bottom, which is possibly related to the difference in observation positions relative to the cloud bases. With increasing rain rate, the mass-weighted mean diameter (D_m) of raindrops increased and the standard deviation of generalized intercept parameter (log₁₀N_w) decreased. The RSDs from all sampling positions were in good agreement with the gamma distribution. The evolution of raindrop spectrum was then investigated using three fitting parameters. It was found that compared with RSDs for convective precipitation, the RSDs for stratiform precipitation showed smaller variation between different altitudes, which suggests that its evolution was more stable. Finally, the raindrop falling velocity and its influential factors were studied.
