Abstract

Stroboscopic photographs of falling snowflakes were analysed to tind relationship between the fall velocity and the shape of their component crystals. The fall velocity depends remarkably upon the dominant shape of component crystals, the size or the mass of snowtlakes, and the surface air temperature. Not all of the empirical formulas of fall velocity are expressed with the exponents of diameters of snowflakes melt. The coefficients of nearly all types of snowflakes have decreasing tendency with inceasing Reynolds numbers.
