| Research Abstract |
Field and wind-tunnel observations were carried out and a blowing snow model to estimate blowing-snow sublimation was developed. Using reanalysis products, the effect of blowing-snow sublimation was investigated on a global scale. The regional characteristics of blowing-snow occurrence, the seasonal and interannual variations of blowing-snow sublimation were clarified, and response of blowing-snow sublimation under conditions of recent climate change was shown.
