Implementation of a brittle sea-ice rheology in an Eulerian, finite-difference, C-grid modeling framework: Impact on the simulated deformation of sea-ice in the Arctic by Laurent Brodeau et al., published in Geoscientific Model Development.

In this new preprint, Laurent Brodeau, Pierre Rampal et al. describe how they achieved the numerical implementation of the Brittle Bingham-Maxwell sea-ice rheology (BBM) into SI3, the sea-ice component of NEMO

Fig.7 (from Brodeau and Rampal):PDFs of the (a) shear, (b) divergence, (c) convergence, and (d) total deformation rates at the 10 km spatial and 3-day temporal scale, for RGPS data and their synthetic counterparts constructed using the simulated sea-ice velocities of SI3-BBM an SI3-aEVP. The light gray lines are for reference and correspond to a power-law with an exponent of -3. Below each panel, the departure between the logarithm of the simulated and observed distributions is shown for each bin.
