Deploying a Top-100 Supercomputer for Large Parallel Workloads: the Niagara Supercomputer
Marcelo Ponce, Ramses van Zon, Scott Northrup +14
Niagara is currently the fastest supercomputer accessible to academics in Canada. It was deployed at the beginning of 2018 and has been serving the research community ever since. T…
Self-organized criticality of turbulence in strongly stratified mixing layers
Hesam Salehipour, W. R. Peltier, C. P. Caulfield
Motivated by the importance of stratified shear flows in geophysical and environmental circumstances, we characterize their energetics, mixing and spectral behavior through a serie…
Abrupt climate transition of icy worlds from snowball to moist or runaway greenhouse
Jun Yang, Feng Ding, Ramses M. Ramirez +3
Ongoing and future space missions aim to identify potentially habitable planets in our Solar System and beyond. Planetary habitability is determined not only by a planet's current…
Deep learning of mixing by two 'atoms' of stratified turbulence
Hesam Salehipour, W. Richard Peltier
Current global ocean models rely on ad-hoc parameterizations of diapycnal mixing, in which the efficiency of mixing is globally assumed to be fixed at , despite increasing ev…
