Space and Time Scaling of Sea Ice Deformation: Estimating Sub-Grid Scale Variability

为发展新的北极海冰变形的空间和时间尺度分析提供了基金。这些分析预计将有助于更好地了解海冰的性质，估计全球气候模式中冰变形的亚格子尺度变异性及其对冰生产的影响，并为比较不同的形变测量提供基础。海冰变形被认为是控制海冰厚度在各种时空尺度上分布的重要过程。厚度分布反过来又会影响海冰质量平衡。比例分析试图在统计上关联在不同比例下测量的量。拟议的工作建立在国际和平研究所以前的工作基础上。这将使他能够利用广泛的卫星数据集建立按地区和季节划分的海冰变形比例关系。成功开发比例定律将提供有用的诊断，以测试全球气候模式中正在开发的海冰模块。对海冰厚度分布的更好的理解将有助于在海冰模式中准确地将这一特征参数化。

Stern0612023Funds are provided to develop new spatial and temporal scaling analyses of Arctic sea ice deformation. These analyses are anticipated to result in improved understanding of sea ice properties, estimation of sub-grid scale variability of ice deformation in global climate models and its impact on ice production, and provision of a basis for comparing disparate measurements of deformation. Sea ice deformation is recognized as an important process controlling the ice thickness distribution across a wide range of space and time scales. The thickness distribution, in turn, influences the sea ice mass balance. Scaling analysis attempts to statistically relate quantities measured at different scales. The proposed effort builds on previous work by the PI. It will allow him to establish scaling relationships for sea ice deformation by region and season, using extensive satellite-derived data sets.Successful development of scaling laws will provide useful diagnostics against which to test developing sea ice modules in global climate models. Improved understanding of the distribution of sea ice thickness will contribute to the accurate parameterization of this characteristic in sea ice models.
