Improving the spatial distribution of modeled Arctic sea ice thickness
[1] The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the same deficiencies found in previous studies, namely ice that is too thick in the Beaufort Sea and too thin near the North Pole. We find th...
متن کاملSea ice thickness and recent Arctic warming
The climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus has been set on the role of sea ice thickness, although it strongly determines surface heat fluxes. Here ensembles of simulations using the EC-Earth atmospheric model (Integrated Forecast System) are performed and analyzed to quantify the atmospheric impacts of Arctic sea...
متن کاملArctic Ocean Ice Thickness: Modes of Variability and the Best Locations from Which to Monitor Them*
Model simulations of Arctic sea ice and ocean systems are used to determine the major spatial and temporal modes of variability in the ice thickness. A coupled ice–ocean model is forced with daily NCEP– NCAR reanalysis surface air pressure and surface air temperature fields for the period 1951–2003 with the analysis of the results performed for the 51-yr period 1953–2003. Ice concentration data...
متن کاملAssessment of Spatial and Temporal Variability of Extreme Precipitation Indices (North and West of Iran)
The frequency of precipitation extreme event can cause flood or change the drought period. Accurate understanding of these changes is necessary to take action to reduce these effects. In this research, temporal and spatial changes of 14 precipitation indices for eight synoptic stations in the North and West of the country were investigated. For this purpose, after reconstructing the daily preci...
متن کاملRecent Variability in Sea Ice Cover, Age, and Thickness in the Pacifi c Arctic Region
J.M. Grebmeier and W. Maslowski (eds.), The Pacifi c Arctic Region: Ecosystem Status and Trends in a Rapidly Changing Environment, DOI 10.1007/978-94-017-8863-2_3, © Springer Science+Business Media Dordrecht 2014 Abstract Over the past several decades, there has been a fundamental shift in sea ice cover, age, and thickness across the Pacifi c Arctic Region (PAR). Satellite data reveal that tren...
