| Title: | Study of the formation of precipitation by the aggregation of snow particles and the accretion of cloud droplets on snowflakes. |
| Publication: | Papers in Meteorology and Geophysics, 22, 2, 69-142 |
| Abstract: | Taking stereographical photographs of falling snow particles with a stroboflash, the author has investigated statistically the motion of snow particles in a population in order to determine the collision rate of snow particles, and then proceeded to the study of the formation of snowflakes based on the collision rate thus obtained. |
