海氷の数値予測とその応用

低温科学

Key characteristics of sea ice such as growth, decay, movement, and deformation interact in a complex way to influence polar climate. Accordingly, thermodynamic and dynamic models have been developed separately. Sea ice has been modeled as a continum medium, as well as the atmosphere and ocean have, because of the ease of treatment given this assumption; however, in some experiments sea ice is regarded as a collection of ice floes and thereby modeled using Lagrangian methods and a number of particles. Here, we introduce an outline of sea-ice modeling and consider an application of such modeling to the Sea of Okhotsk, which has a seasonal sea ice extent and is the most familiar ocean in terms of this type of research.
