Response of Sea Ice to the Arctic Oscillation
Data collected by the International Arctic Buoy Programme from 1979 to 1998 are analyzed to obtain statistics of sea level pressure (SLP) and sea ice motion (SIM). The annual and seasonal mean fields agree with those obtained in previous studies of Arctic climatology. The data show a 3-hPa decrease in decadal mean SLP over the central Arctic Ocean between 1979–88 and 1989–98. This decrease in S...
متن کاملDynamical Link between the Barents–Kara Sea Ice and the Arctic Oscillation
The recent accelerated Arctic sea ice decline has been proposed as a possible forcing factor for midlatitude circulation changes, which can be projected onto the Arctic Oscillation (AO) and/or North Atlantic Oscillation (NAO)mode.However, the timing and physicalmechanisms linkingAO responses to theArctic sea ice forcing are not entirely understood. In this study, the authors suggest a connectio...

متن کاملArctic 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 کاملCombined Effects of the North Atlantic Oscillation and the Arctic Oscillation on Sea Surface Temperature in the Alborán Sea
We explored the possible effects of the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) on interannual sea surface temperature (SST) variations in the Alborán Sea, both separately and combined. The probability of observing mean annual SST values higher than average was related to NAO and AO values of the previous year. The effect of NAO on SST was negative, while that of AO was pos...
