Abstract Most viscous‐plastic sea ice models use the elliptical yield curve. This yield curve has a fundamental flaw: it excludes acute angles between deformation features at high resolution. Conceptually, the teardrop (TD) and parabolic lens (PL)

Wind imparts energy via surface stress to sea ice where it leads to internal stress and motion. The ocean also exerts a drag that slows down ice motion, but the internal stress dissipates part of the energy in convergent and shear motion (ridging). T

Deformation in sea ice takes the shape of narrow lines of high deformation, called the Linear Kinematic Features or LKFs. The distribution of intersection angles between LKFs indicates that the yield curve of sea ice is closer to the shape of a Mohr-

In Arctic sea ice, the intersection angles between Linear Kinematic Features (LKFs) are linked to the internal mechanical properties. Sea ice rheological models struggle to reproduce the intersection angles between LKFs in Arctic sea ice. We aim to o

Recent high-resolution pan-Arctic sea ice simulations show fracture patterns (linear kinematic features or LKFs) that are typical of granular materials but with wider fracture angles than those observed in high-resolution satellite images. Motivated

EPIC3vEGU21: Gather Online, Online, 2021-04-19-2021-04-30Alternative viscous-plastic rheologies for the representation of fracture lines in high-resolution sea ice models
Fracture lines dominate the dynamics of sea ice. They affect the ice mass balance and the heat transfer between the atmosphere and the ocean. Therefore, climate modeling and sea ice prediction require an accurate fracture representation. Most sea ice
