Laboratory Studies of Internal Solitary Waves Propagating and Breaking over Submarine Canyons

Journal of Marine Science and Engineering, 2023
This paper carried out laboratory experiments to study evolution of internal solitary waves (ISWs) over submarine canyons with a combination of PIV (particle image velocimetry) and PLIF (planar laser-induced fluorescence) techniques.

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Interaction between coherent structures and surface temperature and its effect on ground heat flux in an unstably stratified boundary layer [PDF]

, 2013
Surface layer plumes, thermals, downdrafts and roll vortices are the most prominent coherent structures in an unstably stratified boundary layer. They contribute most of the temperature and vertical velocity variance, and their time scales increase with ...

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...
