Abstract

This study examined the effect of new mass-weighted sedimentation velocities of snow and graupel in the WSM6 microphysics scheme, based on the observational evidence. Sensitivity tests were carried out for an idealized storm case and a heavy rainfall event over Korea. The new formula increases (decreases) snow (graupel) at the relatively warm temperatures, leading to improving the distribution of hydrometeors as compared with observed data. Also it was found out that the new velocity for graupel and snow alleviates excessive precipitation problem in the WSM6 scheme.
