Successful simulation of the lead formation in Arctic sea-ice

Scientists from the Alfred-Wegener-Institute (AWI) and the University of Hamburg have succeeded in realistically simulating the emergence of large channels in the Arctic sea ice in a computer model. Two approaches were decisive for this success: On the one hand, the researchers had increased the spatial resolution of the FESOM AWI sea-ice ocean model. On the other hand, they were able to improve the numerical solution to the equation so that the simulation of the lead formation holds up well when compared to real sea-ice satellite data. This video shows how the model is simulating the formation of leads in the Arctic sea-ice cover the years 2005 to 2014.
