Based on the availability of hemispheric gridded data sets from observations, analysis and
global climate models, objective cyclone identification methods were developed and applied …

Marine ecosystems are undergoing rapid change at local and global scales. To understand
these changes, including the relative roles of natural variability and anthropogenic effects …

We examine the basinwide trends in sea ice circulation and drift speed and highlight the
changes between 1982 and 2009 in connection to regional winds, multiyear sea ice …

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 …

Changes apparent in the arctic climate system in recent years require evaluation in a
century-scale perspective in order to assess the Arctic's response to increasing …

The North Atlantic Oscillation is the dominant mode of atmospheric variability in the North
Atlantic Sector. Basin scale changes in the atmospheric forcing significantly affect the …

The pattern of recent surface warming observed in the Arctic exhibits both polar amplification
and a strong relation with trends in the Arctic Oscillation mode of atmospheric circulation …

Sea ice plays a crucial role in the Earth's energy and water budget and has a substantial
impact on local and remote atmospheric and oceanic circulations. Predictions of Arctic sea …

A new long-term data record of Fram Strait sea ice area export from 1935 to 2014 is
developed using a combination of satellite radar images and station observations of surface …

A new, well-verified, multiproxy reconstruction of the winter North Atlantic Oscillation (NAO)
index is described that can be used to examine the variability of the NAO prior to twentieth …
