WebTheoretical relations between visibility and snowfall liquid equivalent rate (Rasmussen et al. 1999) show that visibility is inversely proportional to snowfall rate. At a rate of 1 mm/hr rate, the visibility is 1 km. Thus, the equation relating the visibility to rate can be understood as: Rate (mm/hr) = 1/(Visibility(km)) WebThe snow water equivalent is the product of snow depth and snow density. New snow …
