Snow Studies. Part II: Average Relationship between Mass of Snowflakes and Their Terminal Fall Velocity

  title={Snow Studies. Part II: Average Relationship between Mass of Snowflakes and Their Terminal Fall Velocity},
  author={Wanda Szyrmer and Isztar Zawadzki},
  journal={Journal of the Atmospheric Sciences},
Abstract This study uses a dataset of low-density snow aggregates measurements collected by a ground-based optical disdrometer that provides particle size and terminal fall speed for each size interval from which the velocity–size and area ratio–size relationships can be derived. From these relationships and relations between the Best and Reynolds numbers proposed in the literature, the mass power-law coefficients are obtained. Then, an approximate average relation between the coefficients in…
