WebWe develop and demonstrate a model for the evolution of the joint sea-ice floe size and thickness distribution that depends on atmospheric and oceanic forcing fields. The model accounts for effects due to multiple processes that are active in the MIZ and seasonal ice zones: freezing and melting along the lateral side and base of floes ... WebApr 9, 2024 · At the same time, stronger and sometimes opposing regional fluctuations in sea-ice extent and seasonality are occurring; in the Ross Sea, sea-ice extent and seasonal sea-ice duration have increased by 4.5–5% per decade and ~2.4 days per year, respectively, whereas both have decreased by 5–6% per decade and ~3.1 days per year, respectively ...
WebJul 30, 2012 · At the same time, the size distribution of sea ice floes does not exhibit the random (Poissonian-like) statistics and follows the power law typical for scaling (fractal) structures [ 1, 2 ]. The conventional mechanics cannot explain this phenomenon. WebJul 26, 2024 · The size distribution of sea ice floes, commonly known as floe size distribution (FSD), characterizes the sub-grid-scale composition of the sea ice field. The FSD is a probability distribution f ( x ), where f ( x) dx is the fraction of a domain composed of ice with a floe size x, a measure of the lateral extent of the floes, between x and x + dx.
