Atlantic Water Circulation and Properties Northwest of Svalbard During Anomalous Southerly Winds
(Journal article; Peer reviewed, 2022)Atlantic Water (AW), the main source of heat and salt for the Arctic Ocean, undergoes large transformations (cooling and freshening) north of Svalbard as it flows near the surface above the Yermak Plateau (YP). In September ... -
The Atlantic Water flow along the Vøring Plateau: Detecting frontal structures in oceanic station time series
(Journal article, 2007-01-13)The topographic steering of the baroclinic western branch of the Norwegian Atlantic Current (NwAC) determines the extent of Atlantic Water and location of the Arctic Front in the Nordic Seas. In this paper the geographical ... -
Atlantic Water in the Arctic Ocean - Mechanisms and Impacts
(Doctoral thesis, 2021-08-19)The Arctic Ocean plays a fundamental role in regulating Earth’s climate, and a changing Arctic will affect climate, weather, and life everywhere on the planet. Understanding the fundamental dynamics and mechanisms driving ... -
Atlantic water inflow into the Arctic Ocean: studies of pathways, transport and mixing processes using observations from ships and autonomous underwater vehicles
(Doctoral thesis, 2024-01-23)Nordishavet spiller en viktig rolle i det globale klimasystemet. Produksjon av kaldt vann med høy tetthet, samt frysing av sjøis i Arktis, bidrar til å drive den Atlantiske meridionale omveltningssirkulasjonen og kan påvirke ... -
Atlantic Water Inflow Through the Yermak Pass Branch: Evolution Since 2007
(Journal article; Peer reviewed, 2022)Thirty-four months (2017–2020) of mooring data were recently obtained at 80.6°N, 7.26°E in the main branch of Atlantic Water inflow to the Arctic, the Yermak Pass Branch. The Yermak Pass Branch was sampled at that same ... -
Atlantic Water Pathways Along the North-Western Svalbard Shelf Mapped Using Vessel-Mounted Current Profilers
(Peer reviewed; Journal article, 2019-03)A large amount of warm Atlantic water (AW) enters the Arctic as a boundary current through Fram Strait (West Spitsbergen Current [WSC]) and is the major oceanic heat source to the Arctic Ocean. Along the north‐western ... -
Atlantic water properties, transport and heat loss from mooring observations north of Svalbard
(Journal article; Peer reviewed, 2022)The Atlantic Water inflow to the Arctic Ocean is transformed and modified in the area north of Svalbard, which influences the Arctic Ocean heat and salt budget. Year-round observations are relatively sparse in this region ... -
Atlantic water transformation along its poleward pathway across the Nordic Seas
(Peer reviewed; Journal article, 2018-08-23)The warm and salty Atlantic Water is substantially modified along its poleward transit across the Nordic Seas, where it reaches deeper isopycnals. In particular, the Lofoten Basin, exposed to intense air‐sea interactions, ... -
An Atlantic-driven rapid circulation change in the North Pacific Ocean during the late 1990s
(Peer reviewed; Journal article, 2019-10-08)Interbasin interactions have been increasingly emphasized in recent years due to their roles in shaping climate trends and the global warming hiatus in the northern hemisphere. The profound influence from the North Atlantic ... -
Atlantic-Origin Overflow Water in the East Greenland Current
(Peer reviewed; Journal article, 2019)Dense water masses transported southward along the east coast of Greenland in the East Greenland Current (EGC) form the largest contribution to the Denmark Strait Overflow. When exiting Denmark Strait these dense water ... -
Atmosphere-Snow Exchange Explains Surface Snow Isotope Variability
(Journal article; Peer reviewed, 2022)The climate signal imprinted in the snow isotopic composition allows to infer past climate variability from ice core stable water isotope records. The concurrent evolution of vapor and surface snow isotopic composition ... -
Atmospheric boundary layers in storms: advanced theory and modelling applications
(Peer reviewed; Journal article, 2005-03-29)Turbulent planetary boundary layers (PBLs) control the exchange processes between the atmosphere and the ocean/land. The key problems of PBL physics are to determine the PBL height, the momentum, energy and matter fluxes ... -
Atmospheric Circulation Response to Short-Term Arctic Warming in an Idealized Model
(Journal article; Peer reviewed, 2020)Recent Arctic sea ice loss in fall has been posited to drive midlatitude circulation changes into winter and even spring. Past work has shown that sea ice loss can indeed trigger a weakening of the stratospheric polar ... -
Atmospheric Climatologies Over Isfjorden, Svalbard
(Journal article; Peer reviewed, 2023)The Isfjorden region at the west coast of Spitsbergen is the most easily accessible area in the Svalbard Archipelago, making it a perfect outdoor laboratory for Arctic research. Due to its location in the high Arctic ... -
Atmospheric Contributions to the Reversal of Surface Temperature Anomalies Between Early and Late Winter Over Eurasia
(Journal article; Peer reviewed, 2022)Observations have shown subseasonal reversal of temperature anomalies between early and late winter over Eurasia, which is distinct from the seasonal mean condition. Based on the reanalysis data, the 1800-year control ... -
Atmospheric Drivers of Wind Turbine Blade Leading Edge Erosion: Review and Recommendations for Future Research
(Journal article; Peer reviewed, 2022)Leading edge erosion (LEE) of wind turbine blades causes decreased aerodynamic performance leading to lower power production and revenue and increased operations and maintenance costs. LEE is caused primarily by materials ... -

Atmospheric response to removal of Southern Hemisphere sea ice - a model study
(Master thesis, 2010-06-01)The atmospheric response to the removal of Southern Hemisphere sea ice is studied using the ICTP AGCM (SPEEDY) model with an uncoupled ocean. The results show large increases in surface heat flux from the ocean to the ... -
Atmospheric response to zonally averaged sea surface temperatures in the North Atlantic - a model study
(Master thesis, 2008-05-29)A less dynamically active ocean will most likely lead to a more zonal sea surface temperature (SST) distribution. In order to identify if, and how such an effect affects the atmospheric variability, idealized experiments ... -
