-          <p class="mb-0"></p>My collaborators and I have impleted an Antartic version of neXtSIM which has been validated and its results will be published soon. We compare two versions of neXtSIM in this study using a modified Viscous-Elastic-Plastic (mEVP - used in climate models) and a Brittle Bigham-Maxwell rheology (science of material deformation). In the video below, one can see that in the mEVP run sea ice moves slowly and fails at representing mesoscale drift features. The BBM run is able to reproce cyclonic features in sea ice drift forced by the passage of cyclones (example: Weddell sea on the 10th of Aug 2016). This happens because the BBM run reproduces ice fractures more realistically (previous video) which makes the ice more free to move.</p>
