Fast Low-to-High Confinement Mode Bifurcation Dynamics in a Tokamak Edge Plasma Gyrokinetic Simulation. [PDF]

open access: yesPhysical Review Letters, 2017
Transport barrier formation and its relation to sheared flows in fluids and plasmas are of fundamental interest in various natural and laboratory observations and of critical importance in achieving an economical energy production in a magnetic fusion ...

Albedo parametrization and reversibility of sea ice decay [PDF]

open access: yesNonlinear Processes in Geophysics, 2012
The Arctic's sea ice cover has been receding rapidly in recent years, and global climate models typically predict a further decline over the next century. It is an open question whether a possible loss of Arctic sea ice is reversible.

Variability of Longshore Surface Current on the Shelf Edge and Continental Slope off the West Coast of Canada

open access: yesRemote Sensing, 2022
The shelf-edge and continental slope current off the west coast of Canada has been monitored at a site off West Vancouver Island since 1985. However, observations at this site may not represent the characteristics of the shelf-edge and slope current off ...

Reversal of ocean gyres near ice shelves in the Amundsen Sea caused by the interaction of sea ice and wind [PDF]

open access: yesThe Cryosphere, 2022
Floating ice shelves buttress the Antarctic Ice Sheet, which is losing mass rapidly mainly due to ocean-driven melting and the associated disruption to glacial dynamics.

SITool (v1.0) – a new evaluation tool for large-scale sea ice simulations: application to CMIP6 OMIP [PDF]

open access: yesGeoscientific Model Development, 2021
The Sea Ice Evaluation Tool (SITool) described in this paper is a performance metrics and diagnostics tool developed to evaluate the skill of Arctic and Antarctic model reconstructions of sea ice concentration, extent, edge location, drift, thickness ...

Zonal direct-hybrid aeroacoustic simulation of trailing edge noise using a high-order discontinuous Galerkin spectral element method

open access: yesActa Acustica, 2022
We present the extension of a discontinuous Galerkin framework to zonal direct-hybrid aeroacoustic simulations. This extension provides the ability to simultaneously perform a zonal large eddy simulation (LES), solving the compressible Navier–Stokes ...

Variations of zero forcing and power domination

open access: yes, 2021
Zero forcing is a propagation process on a graph that turns white vertices into blue vertices. In this process, an initial set of vertices in a graph $G$ are chosen to be blue and all others are colored white, then a color-change rule is iteratively ...

First forcing estimates from the future CMIP6 scenarios of anthropogenic aerosol optical properties and an associated Twomey effect [PDF]

open access: yesGeoscientific Model Development, 2019
We present the first forcing interpretation of the future anthropogenic aerosol scenarios of CMIP6 with the simple plumes parameterisation MACv2-SP. The nine scenarios for 2015 to 2100 are based on anthropogenic aerosol emissions for use in CMIP6 (Riahi ...

Complete Forcing Numbers of Random Multiple Hexagonal Chains

open access: yes, 2021
Let G be a simple connected graph with vertex set V(G) and edge set E(G) that admits a perfect matching M. A forcing set of M is a subset of M contained in no other perfect matchings of G.
