Comparative Analysis of Microphysical Characteristics between Wet and Dry Snow in Northeast China Based on Disdrometer Observations

---

ABSTRACT: Northeast China experiences significant snowstorms during winter. However, the microphysics of snowfall in this area remains poorly understood. This study aims to address this gap by comparing the microphysical characteristics and related meteorological conditions of wet and dry snow in Northeast China. The results indicate that the number concentration (NC) of wet snow is approximately twice that of dry snow, contributing to the liquid-equivalent snow rate (SR) being approximately twice as high in wet snow compared to dry snow. The formation and dissipation of wet snow are primarily attributed to the sharp increase and decrease in the NC of small size particles, respectively, while for typical dry snow, they are largely ascribed to the broadening and shrinking of the snow particle spectra along the diameter dimension. Although the intensification of snow processes usually involves both accelerated generation and growth of snow particles, wet snow is characterized by the faster generation of denser but smaller particles, while dry snowfall corresponds to faster growth of sparser but larger particles. The linear-fit line of the m?L (two of the three parameters of the gamma model) relationship for wet snow mirrors that of dry snow, and both plot among the previously established linear fit lines for rainfall, albeit with smaller m and L values. The warmer, more humid, faster rising meteorological environments with higher average cloud top heights (CTHs) during wet snow processes contribute to microphysical differences between wet and dry snow.
