The PIC method is introduced into the sea ice model to efficiently reduce the numeric diffusion inherent in conventional models.

They also look very similar to the simulations coming out of Piomas (Pan-Arctic Ice-Ocean Modelling and Assimilation System), an influential computer model that has been used to estimate Arctic sea-ice volume and which has been the basis for several predictions about when summer sea ice might disappear completely.

But how we do it is take the bench-top physics class model, where you mix nitrogen and ice cream in a bowl and stir it up with a spoon.

Unfortunately for snow enthusiasts, the model found that the fragile needle-like ice crystals connecting the two layers can be broken easily and separated by the weight of new snow or a skier.
