Research Abstract

Blowing snow often causes low visibility and snow drift and sometimes leads to a disaster such as a serious traffic accident. However, inexpensive proper instruments for blowing snow observation have not been available. Thus, the characteristics of blowing snow variation are not clarified. The purpose of this study is to develop inexpensive instruments for blowing snow measurements. Acoustic sensors were used to investigate the relationship between out-put from the sensor and mass flux of snow in cold laboratory experiments. The results showed that variance of out-put from the sensor increased with snow mass flux, which implies an efficiency of acoustic sensors for blowing snow observation.
