The evolution of scaling laws in the sea ice floe size distribution
The sub-gridscale floe size and thickness distribution (FSTD) is an emerging climate variable, playing a leading-order role in the coupling between sea ice, the ocean, and the atmosphere. The FSTD, however, is difficult to measure given the vast range of horizontal scales of individual floes, leading to the common use of power-law scaling to describe it. The evolution of a coupled mixed-layer-F...
متن کاملSea ice floe size distribution in the marginal ice zone: Theory and numerical experiments
To better describe the state of sea ice in the marginal ice zone (MIZ) with floes of varying thicknesses and sizes, both an ice thickness distribution (ITD) and a floe size distribution (FSD) are needed. In this work, we have developed a FSD theory that is coupled to the ITD theory of Thorndike et al. (1975) in order to explicitly simulate the evolution of FSD and ITD jointly. The FSD theory in...
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 کاملAlbedo evolution of seasonal Arctic sea ice
[1] There is an ongoing shift in the Arctic sea ice cover from multiyear ice to seasonal ice. Here we examine the impact of this shift on sea ice albedo. Our analysis of observations from four years of field experiments indicates that seasonal ice undergoes an albedo evolution with seven phases; cold snow, melting snow, pond formation, pond drainage, pond evolution, open water, and freezeup. On...
متن کاملA Review on Sea Ice Floe Analysis
Sea ice mapping is one of the important applications of remote sensing technology. Remote sensing is safe navigation for ships where ice caps are form and it is essential to understand the climate conditions of the oceans. The main function of ice mapping is to generate the maps of sea ice according to their geographical location. This paper reviews most of the recent research work on Sea ice f...
