The Arctic Ocean's Beaufort Gyre is a dominant feature of the Arctic system, a prominent
indicator of climate change, and possibly a control factor for high-latitude climate. The state …

Atmospheric humidity, clouds, precipitation, and evapotranspiration are essential
components of the Arctic climate system. During recent decades, specific humidity and …

Key observational indicators of climate change in the Arctic, most spanning a 47 year period
(1971–2017) demonstrate fundamental changes among nine key elements of the Arctic …

Atmospheric reanalyses were validated against tethersonde sounding data on air
temperature, air humidity and wind speed, collected during the drifting ice station Tara in the …

Annual minima in Arctic sea-ice extent and volume have been decreasing rapidly since the
late 1970s, with substantial interannual variability. Summers with a particularly strong …

The atmospheric water cycle of the Arctic is evaluated via seven global reanalyses and in
radiosonde observations covering the 1979–2013 period. In the regional moisture budget …

The polar regions have been undergoing amplified warming in recent years. In particular,
Greenland has experienced anomalously warm summers with intense melt rates. We …

In this study, ERA5 reanalysis is used to quantify cyclone‐induced moisture transport into
the Arctic on a seasonal basis (1998–2018). Moist airstreams are spatially identified and …

Arctic trends of integrated water vapor were analyzed based on four reanalyses and
radiosonde data over 1979–2016. Averaged over the region north of 70° N, the Arctic …

We carried out upper air measurements with radiosondes during the summer over the Arctic
Ocean from an icebreaker moving poleward from an ice-free region, through the ice edge …
