The Sea Ice extent data product is based on gridded fields of sea ice concentration data derived from passive microwave radiometers and is commonly used for monitoring and analyzing changes in Arctic sea ice extent over time81. The dataset used to analyze the thinning of ice cover in the ...
Inter-annual to multi-decadal Arctic sea ice extent trends in a warming world. Geophys. Res. Let. https://doi.org/10.1029/2011GL048008 (2011). Mueller, B., Gillett, N., Monahan, A. & Zwiers, F. Attribution of Arctic sea ice decline from 1953 to 2012 to influences from natural, ...
While many models have been used to study the predictability of climate variables, their performance in predicting sea ice was not well assessed. This study examines the predictability of the Arctic sea ice extent from ensemble prediction systems. The analysis is focused on verification of ...
被引量: 0发表: 2023年 When Will Arctic Sea Ice Disappear? Projections of Area, Extent, Thickness, and Volume Rapidly diminishing Arctic summer sea ice is a strong signal of the pace of global climate change. We provide point, interval, and density forecasts for four measures of Arctic sea ...
[1] How well can the extent of arctic sea ice be predicted for lead periods of up to one year? The forecast ability of a linear empirical model is explored. It uses as predictors historical information about the ocean and ice obtained from an ice–ocean model retrospective analysis. The mo...
Wintertime Arctic sea ice extent has been declining since the late twentieth century, particularly over the Atlantic sector that encompasses the Barents-Kara Seas and Baffin Bay. This sea ice decline is attributable to various Arctic environmental changes, such as enhanced downward infrared (IR) radia...
The LANDSAT-1 satellite imagery at a scale of 1: 1000000 has proven ideal for mapping the regional extent of this former snow-cover and this is illustraled by two frames from north-central Baffin Island. Interpretation problems can arise from a number of sources, such as: light early summer...
July Arctic sea ice area has been stable for 17 years. Nothing is melting anymore. Hat-tip: Snowfan here. Image: DMI Arctic Plots Sea Ice Extent The National Snow And Ice Data center (NSIDC) analysis of August 4, 2024 shows that the Arctic sea ice extent in July 2024 has been stable...
Self-Organizing maps (SOMs) have been used to explore potential connections between atmospheric circulation over the Arctic (in the form of sea level pressure patterns and teleconnection indices) and sea ice loss. Extended periods of abrupt loss (rapid ice loss events, or RILEs) have been studied...
The snow cover extent between May and June has decreased by 21% over the 1971–2019 period1; this is a percent loss rate greater than the loss of sea ice in September. Both rainfall and snow dynamics are among the key factors driving soil moisture availability that, at the same time, ...
