The WRF simulated precipitation data were assimilated to the observation-based PRISM data in order to obtain the accurate hourly snow precipitation data. Combining all the weather variables RS06215 1703F Historical Winter Weather Assessment for Snow Fence Design, the number of blowing snow events is found to be increasing despite the increasing air temperature because of the sufficiently cold winters of WyomiRS06215 1703F Historical Winter Weather Assessment for Snow Fence Design
