The transformation of the rain and snow phase is the focus and difficulty of the winter precipitation forecast service in Zhejiang Province. This paper uses the NCEP reanalysis grid data, the data from automatic weather stations in Zhejiang province, and the two wind profile radar observation data to conduct a comparative analysis of meteorological elements for the different precipitation phases of different regions induced by a severe cold wave in Jan. 2016. The results showed that: high altitude strong cold advection, middle and low level strong warm and humid air flow provided good dynamic and vapor conditions for the rain and snow process; a comparative analysis found that under the influence of the cold waves of the same intensity, sleet or snow occurred on the coast of North Zhejiang requires a lower temperature of the lower atmosphere than those occurred in the inland of North Zhejiang. According to the Φ_{850-1 000}, Φ_{925-1 000} and T_{2 m} index differences under different precipitation phases, this paper builds the rain and snow evaluation indexes for the coast area and inland area respectively. The test showed that the statistical index is of good reference value for the forecast of rain and snow phases in North Zhejiang. The average changes of vertical velocity of the boundary layer below 500 m from the wind profile radar data can help determine the phase change of ground rain and snow and the strength of ground snowfall.
