Abstract

Immersion freezing tests of fresh snow collected in Kanazawa, Japan was conducted. The snow samples were melted at 4°C and tested between-5 to-12°C with non-treatment, with heat treatment at 40°C and with heat treatment at 90°C. Detected numbers of ice nuclei in the snow decreased as the temperature of heat treatments increases. Additionally, numbers of ice nuclei with non-treatment and with heat treatment at 40°C were predominant over-9°C. These results suggest that ice nuclei in fresh snow including biological ice nuclei are more sensitive to temperature less than or equal to 40°C.
