| Research Abstract |
We started to develop a simple blowing snow observation device. A small wind turbine, solar panel and a cold-proof buttery were utilized as a power source. Firstly, its performance was tested in a cold wind tunnel system and it proved adequately fit for practical use. The systems have been set at Yahiko-yama in Niigata, Ishikari and Shintoku in Hokkaido, Japan and at Col du Lac blanc in France. In 2013, eventually, it was installed at S16 near Syowa station in Antarctica, and succeeded to measure the blowing snow for two months. Further, the blowing snow observation system including the SPC (Snow Particle Counter) was set on the tower at the French base to reveal the flux profile, on the icebreaker to understand the production of polar sea salt mechanism in the Weddell Sea by British Antarctic Survey. Lastly, applying the WRF, blowing snow around the Mizuho station was estimated and compared with the observed data in 2000.
