11 Current sea ice models use numerical schemes based on a splitting in time 12 between the momentum and continuity equations. Because the ice strength 13 is explicit when solving the momentum equation, this can create unrealis14 tic ice stress gradients when using a large time step. As a consequence, 15 noise develops in the numerical solution and these models can even become 16 numerically unstable at high resolution. To resolve this issue, we have imple17 mented an iterated IMplicit-EXplicit… CONTINUE READING
