The size-distribution of falling snow flake was observed by employing the condenser paper coated with the powder of water blue pigment. It appears, on an average, that the number of small snow flake is greater than the large one. The distribution curves of the mass are flat or sharp. With a large amount of falling snow, equivalent water drops of snow flakes are 0.5 mm to 0.75 mm in diameter.
