摘要：	Blowing snow frequently causes serious troubles such as traffic accidents in snowy areas. Many countermeasures against blowing snow have been constructed in Japan. This paper suggests developing a method to study temporal and areal variation of blowing snow with an automatic multiple sensor system to cover areas where blowing snow is frequently experienced. The paper presents a prototype of acoustic blowing snow sensor that was tested in cold wind tunnel experiments to explore the possibility of developing such a sensor. The results showed that spectral densities of some characteristic frequencies of acoustic signals were correlated with snow drift transport rate. This relationship can be applied to estimate snow drift transport rate from acoustic signals.
