Has Arctic Sea Ice Loss Contributed to Increased Surface Melting of the Greenland Ice Sheet?
In recent decades, the Greenland ice sheet has experienced increased surface melt. However, the underlying cause of this increased surface melting and how it relates to cryospheric changes across the Arctic remain unclear. Here it is shown that an important contributing factor is the decreasingArctic sea ice. Reduced summer sea ice favors stronger and more frequent occurrences of blocking-high ...
متن کاملSimulating the Greenland ice sheet under present-day and palaeo constraints including a new discharge parameterization
In this paper, we propose a new sub-grid scale parameterization for the ice discharge into the ocean through outlet glaciers and inspect the role of different observational and palaeo constraints for the choice of an optimal set of model parameters. This parameterization was introduced into the polythermal ice-sheet model SICOPOLIS, which is coupled to the regional climate model of intermediate...
متن کاملMass Balance of the Greenland Ice Sheet at High Elevations.
Comparison of ice discharge from higher elevation areas of the entire Greenland Ice Sheet with total snow accumulation gives estimates of ice thickening rates over the past few decades. On average, the region has been in balance, but with thickening of 21 centimeters per year in the southwest and thinning of 30 centimeters per year in the southeast. The north of the ice sheet shows less variabi...
متن کاملSurface mass-balance changes of the Greenland ice sheet
Mass loss from the Greenland ice sheet over the past decade has caused the impression that the ice sheet has been behaving anomalously to the warming of the 1990s. We have reconstructed the recent (1866–2005) surface mass-balance (SMB) history of the Greenland ice sheet on a 5 5 km grid using a runoff-retention model based on the positive degree-day method. The model is forced with new datasets...
متن کاملHigh resolution (1 km) positive degree-day modelling of Greenland ice sheet surface mass balance, 1870–2012 using reanalysis data
We show results from a positive degree-day (PDD) model of Greenland ice sheet (GrIS) surface mass balance (SMB), 1870–2012, forced with reanalysis data. The model includes an improved daily temperature parameterization as compared with a previous version and is run at 1 km rather than 5 km resolution. The improvements leadoverall tohigher SMBwith the same forcingdata.Wealsocompare ourmodel with...
