downward gravitational settling and upward turbulent diffusion leads to the suspension of blowing snow. In severe blizzards, snow particles transported by turbulent eddies can be found up to several hundred meters above the surface ( King and Turner 1997 ). The model used to simulate these processes is based on the PIEKTUK blowing snow model, developed for the Arctic tundra ( Déry and Taylor 1996 ; Déry et al. 1998 ). For completeness, a brief history of PIEKTUK is given here. PIEKTUK depicts the

are often of Arctic origin (PW; Straneo et al. 2012 ). In Upernavik fjord, the deep waters are believed to originate from the south ( Vermassen et al. 2019 ) and enter the area through a deep cross-shelf trough ( Fig. 2 ) and we therefore identify these waters as AW. This deep fjord water flows unmodified from the shelf at sill depth. The lighter, upper layer on the shelf is defined as PW. In this study we are particularly interested in the PW layer that has the same density as the GMW, and
