15: MIZMAS: Modeling the Evolution of Ice Thickness and Floe Size Distributions in the Marginal Ice Zone of the Chukchi and Beaufort Seas
نویسندگان
چکیده
Our long-term goal is to develop a robust, high-resolution coupled sea ice–ocean modeling and assimilation system that is capable of accurately predicting sea ice conditions in the marginal ice zone (MIZ) of the Chukchi and Beaufort seas (CBS) on seasonal time scales. Our primary interest is the ability to realistically simulate the evolution of the multicategory ice thickness and floe size distributions (ITD, FSD) jointly in the CBS MIZ. Particularly, we would like to improve model physics to represent changes in FSD due to ice advection, thermodynamic growth or decay, lateral melting, ridging and rafting, and wave-induced fragmentation through theoretical development and numerical implementation.

Wind and wave influences on sea ice floe size and leads in the Beaufort and Chukchi Seas during the summerfall transition 2014
Sea ice floe size distribution and lead properties in the Beaufort and Chukchi Seas are studied in the summer-fall transition 2014 to examine the impact on the sea ice cover from storms and surface waves. Floe size distributions are analyzed from MEDEA, Landsat8, and RADARSAT-2 imagery, with a resolution span of 1–100 m. Landsat8 imagery is also used to identify the orientation and spacing of l...
متن کاملAtmospheric Profiles, Clouds and the Evolution of Sea Ice Cover in the Beaufort and Chukchi Seas
This is a collaborative research project with the University of Washington (Axel Schweiger, PI). Its purpose is to examine the role of sea-ice and cloud interactions in the retreat of the seasonal ice zone (SIZ). As sea ice retreats further, changes in lower atmospheric temperature, humidity, winds, and clouds are likely to result from changed sea ice concentrations and ocean temperatures. Thes...

متن کاملA prognostic model of the sea-ice floe size and thickness distribution
Sea ice exhibits considerable seasonal and longerterm variations in extent, concentration, thickness, and age, and is characterized by a complex and continuously changing distribution of floe sizes and thicknesses, particularly in the marginal ice zone (MIZ). Models of sea ice used in current climate models keep track of its concentration and of the distribution of ice thicknesses, but do not a...
متن کاملStorm Surges in the Beaufort and Chukchi Seas
Specific problems of storm surge modeling in the polar seas are analyzed. The vertically integrated equations of motion and continuity are applied to the prediction of the storm surge wave in both the ice-free and ice-covered seas. The interactions of atmosphere, ice, and water are expressed by the normal and tangential stresses. A numerical grid is set over the Chukchi and Beaufort seas, and t...
