| 摘要： | Information on the occurrence of blowing snow is useful in enabling drivers to select safer and more appropriate routes. Visibility meters have been used to measure the intensity of blowing snow on roads. However, the area covered by the visibility meters now used is too limited to obtain region-wide information on blowing snow. The paper describes a method of estimating the intensity of blowing snow using wind velocity, snowfall intensity and other parameters that are relatively easily obtained. The visibility estimated using related equations agreed closely with the measured visibility, which indicates that the above visibility estimation method can be applied to region-wide monitoring of blowing snow on roads. |
