A Case Study on Snowfall from Clouds under Subsidence Inversion

[摘要] A case study was made on the snowfall from a cloud layer under subsidence inversion, as the most simple case of snowfall. The observed shapes of snow crystals are shown in Photos. 1-12. Formation of such various snow crystals can be explained from the Ta-S diagram by Nakaya on artificial snow crystals, if the distribution of humidity in the cloud layer is assumed as shown in Fig. 7.
