Near-surface snow particle dynamics from particle tracking velocimetry and turbulence measurements during alpine blowing snow storms by N. O. Aksamit, J. W. Pomeroy

“…Measurements from the first outdoor application of particle tracking velocimetry (PTV) of near-surface blowing snow yield new information on mechanisms for blowing snow initiation, entrainment, and rebound, whilst also confirming some findings from wind tunnel observations. Blowing snow particle movement is influenced by complex surface flow dynamics, including saltation development from creep that has not previously been measured for snow. …”
