Linkages between atmospheric blocking, sea ice export through Fram Strait and the Atlantic Meridional Overturning Circulation
As a key persistent component of the atmospheric dynamics, the North Atlantic blocking activity has been linked to extreme climatic phenomena in the European sector. It has also been linked to Atlantic multidecadal ocean variability, but its potential links to rapid oceanic changes have not been investigated. Using a global ocean-sea ice model forced with atmospheric reanalysis data, here it is...
متن کاملA link between Fram Strait sea ice export and atmospheric planetary wave phase
[1] A link is found between the variability of Fram Strait sea ice export and the phase of zonal wave 1 in SLP for the period 1958– 1997. Previous studies have found that the link between ice export through Fram Strait and the NAO is inconsistent over time scales longer than the last two decades. Inconsistent and low correlations are also found between Fram Strait ice export and the AO index. T...
متن کاملRecent wind driven high sea ice area export in the Fram Strait contributes to Arctic sea ice decline
Arctic sea ice area has been decreasing for the past two decades. Apart from melting, the southward drift through Fram Strait is the main ice loss mechanism. We present high resolution sea ice drift data across 79 N from 2004 to 2010. Ice drift has been derived from radar satellite data and corresponds well with variability in local geostrophic wind. The underlying East Greenland current contri...
متن کاملHolocene cooling culminates in sea ice oscillations in Fram Strait
A reconstruction of Holocene sea ice conditions in the Fram Strait provides insight into the palaeoenvironmental and palaeoceanographic development of this climate sensitive area during the past 8500 years BP. Organic geochemical analyses of sediment cores from eastern and western Fram Strait enable the identification of variations in the ice coverage that can be linked to changes in the oceani...
متن کاملThe role of Fram Strait winter cyclones on sea ice flux and on Spitsbergen air temperatures
[1] The link between high latitude Atlantic winter cyclone activity and both the climate of Spitsbergen and Fram Strait ice export is examined. Cyclones are more frequent over Fram Strait in relatively mild, low ice export, winters and are associated with south-southwesterly flow around anomalous high pressure over Scandinavia. There is an increased tendency for cyclogenesis to occur off the no...
