Effects of rheology and ice thickness distribution in a dynamic– thermodynamic sea ice model
Realistic treatment of sea ice processes in general circulation models is needed to simulate properly global climate and climate change scenarios. As new sea ice treatments become available, it is necessary to evaluate them in terms of their accuracy and computational time. Here, several dynamic ice...
