Call for Registration: Multi-scale
Modeling of Sea Ice Characteristics and Behavior; Isaac Newton Institute f
or Mathematical Sciences
11-15 September 2017, Cambridge, United Kingd
om
This workshop will address sea ice pr ocesses across a wide range of lengths and time scales, with an emphasis on understanding emergent and scale-invariant phenomena. Mathematical methods that account for the smaller scale processes and enable computation and an alysis of these processes' effect on larger scales relevant for coarse-grai ned climate models will be a focus of the workshop and linkage of scales is a central theme of this workshop.
Registration deadline: Sun day, 11 June 2017.
Workshop Theme:
Realistic models of Earth's climate system are essential to making projections about what we may experience as our climate changes. Polar sea ice forms a critic al system component which must be accurately accounted for in global climat e models. It forms the thin boundary layer coupling the polar oceans and at mosphere and has seen rather dramatic changes over the past two or three de cades. An important feature of sea ice is that it displays rich structure a nd behavior on scales ranging over 10 orders of magnitude, length scales fr om microns to hundreds of kilometers, and time scales from milliseconds to decades. This broad range of scales for sea ice structure and properties is relevant to biological, chemical, industrial, weather, and climate-related processes. It also leads to sea ice structure at certain scales being simi lar to other materials such as porous human bone and polycrystalline metals , which can be used to bring new techniques to studying sea ice.
The complex behavior of sea ice over such a large range of scales presents a fu ndamental challenge to modeling these systems. For example, many key proces ses, whose relevant length scales may be centimeters or meters to kilometer s, impact climate and must be incorporated into largescale numerical climat e models with grid sizes often on the order of tens of kilometers. Moreover , some sea ice properties exhibit scale invariance or predictable scale dep endence while others appear to be wholly emergent, a consequence of interac ting processes within and applied to the ice cover.
Potential wor kshop topics include:
- Large-scale numerical models of the evol
ution of polar sea ice;

redictability, and climate projections;
