DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BAS-PO/6/">S
 ubZero: Floe-Resolving Sea Ice Model</a>\nby Georgy Manucharyan (Universit
 y of Washington) as part of BAS Polar Oceans Seminar\n\n\nAbstract\nSea ic
 e is commonly represented in climate models as a continuous fluid with pre
 scribed rheological properties aimed to represent its motion at relatively
  large scales\, O(100km). However\, at relatively small scales\, O(10 km) 
 and less\, sea ice consists of a collection of strongly interacting floes 
 that undergo frequent fractures leading to large-scale motion. Here\, I wi
 ll present a prototype of a new sea ice model (SubZero) that explicitly si
 mulates the lifecycle of individual sea ice floes. Its various capabilitie
 s will be demonstrated and physical parameterizations will be discussed\, 
 including floe fractures\, welding\, creation from the open ocean\, etc. T
 he key advantage of this model is that its evolution equations can\, in pr
 inciple\, be constrained from observations for each individual process par
 ameterization\, and hence it could present a valuable alternative to exist
 ing rheological models\, the parameters of which do not represent explicit
 ly observable quantities.\n
