Recent Hadley circulation strengthening: a trend or multidecadal variability?
(Journal article; Peer reviewed, 2022)This study explores the possible drivers of the recent Hadley circulation strengthening in the modern reanalyses. Predominantly, two recent generations of reanalyses provided by the European Centre for Medium-Range Weather ... -
Recent Intensified Influence of the Winter North Pacific Sea Surface Temperature on the Mei-Yu Withdrawal Date
(Journal article; Peer reviewed, 2021)The mei-yu withdrawal date (MWD) is a crucial indicator of flood/drought conditions over East Asia. It is characterized by a strong interannual variability, but its underlying mechanism remains unknown. We investigated the ... -
The Role of Atlantic Heat Transport in Future Arctic Winter Sea Ice Loss
(Peer reviewed; Journal article, 2019-05-14)During recent decades Arctic sea ice variability and retreat during winter have largely been a result of variable ocean heat transport (OHT). Here we use the Community Earth System Model (CESM) large ensemble simulation ... -
Role of Atmosphere-ocean-ice Interaction in the Linkage between December Bering Sea Ice and Subsequent February Surface Air Temperature Over North America
(Journal article; Peer reviewed, 2023)This study revealed that the interannual variations of December Bering Sea ice and subsequent February surface air temperature (SAT) over North America are significantly correlated during 2000/01-2020/21, which is not the ... -
Spatial Patterns, Mechanisms, and Predictability of Barents Sea Ice Change
(Journal article; Peer reviewed, 2022)Recent Arctic winter sea ice loss has been most pronounced in the Barents Sea. Here we explore the spatial structure of Barents Sea ice change as observed over the last 40 years. The dominant mode of winter sea ice ... -
Strengthened linkage between November/December North Atlantic Oscillation and subsequent January european precipitation after the late 1980s
(Journal article; Peer reviewed, 2020)This work investigates the nonsynchronous relationship between the North Atlantic Oscillation (NAO) and winter European precipitation. The results indicate that the linkage between early-winter (November and December) NAO ... -
Structure and Forcing of Observed Exchanges across the Greenland–Scotland Ridge
(Peer reviewed; Journal article, 2018)The Atlantic meridional overturning circulation and associated poleward heat transport are balanced by northern heat loss to the atmosphere and corresponding water-mass transformation. The circulation of northward-flowing ... -
Understanding of European Cold Extremes, Sudden Stratospheric Warming, and Siberian Snow Accumulation in the Winter of 2017/18
(Peer reviewed; Journal article, 2020)It is unclear whether the Eurasian snow plays a role in the tropospheric driving of sudden stratospheric warming (SSW). The major SSW event of February 2018 is analyzed using reanalysis datasets. Characterized by predominant ... -
Variable Nordic Seas Inflow Linked to Shifts in North Atlantic Circulation
(Journal article; Peer reviewed, 2021)The inflow across the Iceland-Scotland Ridge determines the amount of heat supplied to the Nordic Seas from the subpolar North Atlantic (SPNA). Consequently, variable inflow properties and volume transport at the ridge ... -
Wave Extremes in the Northeast Atlantic
(Peer reviewed; Journal article, 2012-03)The objective of this study is to compute 100-yr return value estimates of significant wave height using a new hindcast developed by the Norwegian Meteorological Institute. This regional hindcast covers the northeast ... -
Weakening of Cold Halocline Layer Exposes Sea Ice to Oceanic Heat in the Eastern Arctic Ocean
(Journal article; Peer reviewed, 2020)A 15-yr duration record of mooring observations from the eastern (>70°E) Eurasian Basin (EB) of the Arctic Ocean is used to show and quantify the recently increased oceanic heat flux from intermediate-depth (~150–900 m) ...
