Scale Interactions in Turbulence for Mountain Blowing Snow

in canada •  7 years ago 

By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Current study results on Hydrometeorology have been published. According to news originating from Saskatoon, Canada, by VerticalNews correspondents, research stated, “Blowing snow particle transport responds to wind motions across many length and time scales. This coupling is nonlinear by nature and complicated in atmospheric flows where eddies of many sizes are superimposed.”

Funders for this research include Canada Foundation for Innovation, Natural Sciences and Engineering Research Council of Canada, Changing Cold Regions Network, Canada Research Chairs, Alberta Agriculture and Forestry, Global Institute for Water Security, University of Saskatchewan.

Our news journalists obtained a quote from the research from the University of Saskatchewan, “In mountainous terrain, wind flow descriptions are further complicated by topographically influenced or enhanced flows. To improve the current understanding and modeling of blowing snow transport in complex terrain, statistically significant timing and frequencies of wind-snow coupling were identified in high-frequency observations of surface blowing snow and near-surface turbulence from a mountain field site in the Canadian Rockies. Investigation of the mechanisms influencing near-surface, high-frequency turbulence and snow concentration fluctuations provided strong evidence for amplitude modulation from large-scale motions. The large-scale atmospheric motions modulating near-surface turbulence and snow transport were then compared to specific quadrant analysis structures recently identified as relevant for outdoor blowing snow transport. The results suggest that large atmospheric structures modulate the amplitude of high-frequency turbulence and modify turbulence statistics typically used to model blowing snow.”

According to the news editors, the research concluded: “Additionally, blowing snow was preferentially redistributed under the footprint of these same sweep motions, with both low-and high-frequency coherence increasing in their presence.”
