Arctic Sea Ice Extent Prediction
Climate change is a pressing and present issue which has come to be at the forefront in the last few decades. As such, understanding climate change is of utmost importance. In addition to environmental impact, these changes will have social and economic ramifications as these changes will affect the way in which we utilize land and sea resources in the future. The minimum annual arctic sea ice ...
متن کاملA Stochastic Dynamical Model of Arctic Sea Ice
The noise forcing underlying the variability in the Arctic ice cover has a wide range of principally unknown origins. For this reason, the analytical and numerical solutions of a stochastic Arctic sea ice model are analyzed with both additive and multiplicative noise over a wide range of external heat fluxes DF0, corresponding to greenhouse gas forcing. The stochastic variability fundamentally ...
متن کاملDecadal to seasonal variability of Arctic sea ice albedo
[1] A controlling factor in the seasonal and climatological evolution of the sea ice cover is its albedo a. Here we analyze Arctic data from the Advanced Very High Resolution Radiometer (AVHRR) Polar Pathfinder and assess the seasonality and variability of broadband albedo from a 23 year daily record. We produce a histogram of daily albedo over ice covered regions in which the principal albedo ...
متن کاملSources of multi-decadal variability in Arctic sea ice extent
The observed dramatic decrease in September sea ice extent (SIE) has been widely discussed in the scientific literature. Though there is qualitative agreement between observations and ensemble members of the Third Coupled Model Intercomparison Project (CMIP3), it is concerning that the observed trend (1979–2010) is not captured by any ensemble member. The potential sources of this discrepancy i...
