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 icing and meteorological variables: Full scale experiment and testing of models
(Doctoral thesis, 2005-04-15) -
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 ... -
Atmospheric signature of the Agulhas current
(Journal article; Peer reviewed, 2018)Western boundary currents play an important role in the climate system by transporting heat poleward and releasing it to the atmosphere. While their influence on extratropical storms and oceanic rainfall is becoming ... -
Atmospheric-driven state transfer of shore-fast ice in the northeastern Kara Sea
(Journal article, 2005-09-21)Frequencies of observed occurrences of shore-fast ice in the northeastern Kara Sea for each month during 1953–1990 reveal a multimodality of shore-fast ice extent in late winter and spring. The fast ice extent exhibits ... -
Attribution of multi-annual to decadal changes in the climate system: The Large Ensemble Single Forcing Model Intercomparison Project (LESFMIP)
(Journal article; Peer reviewed, 2022)Multi-annual to decadal changes in climate are accompanied by changes in extreme events that cause major impacts on society and severe challenges for adaptation. Early warnings of such changes are now potentially possible ... -
Automated Measurements of Whitecaps on the Ocean Surface from a Buoy-Mounted Camera
(Peer reviewed; Journal article, 2016-12)We quantify the percentage of sea surface covered by whitecaps from images taken by a non-stationary camera mounted on a moored buoy using an Adaptive Thresholding Segmentation (ATS) method and an Iterative Between Class ... -
Autonomous Ocean Turbulence Measurements Using Shear Probes on a Moored Instrument
(Peer reviewed; Journal article, 2014-02)An internally recording, autonomous instrument has been tested for measurements of ocean turbulence from a mooring line. Measurements were made at a single level in the water column, but for an extended period of time, at ... -
Avansert styringssystem for optimalisering av energilagring i distribusjonsnett
(Master thesis, 2019-01-17)I distribusjonsnettet har det lenge blitt opererert med tradisjonell nettutbygging for handtering av kapasitetsproblem eller spenningsproblem. Med stor vekst i tal el-bilar, meir energikrevjande apparat, samt befolkningsvekst ... -
Avvik mellom estimert og faktisk energiproduksjon for småkraftverk
(Master thesis, 2016-06-01)I denne oppgaven har jeg sett på årsakene til avviket mellom estimert og faktisk energiproduksjon for tre av kraftverkene som Småkraft AS sammen med grunneier har hatt i drift i 8-9 år. Kraftverkene jeg har sett på er Ytre ... -
Barents Sea ice cover reflects Atlantic inflow
(Working paper, 2011)The recent Arctic winter sea-ice retreat is most pronounced in the Barents Sea. Using available observations of the Atlantic inflow to the Barents Sea and results from a regional ice-ocean model we assess the role of ... -
Baroclinic Instability in the West Spitsbergen Current
(Peer reviewed; Journal article, 2011-07-15)Baroclinic instability in the West Spitsbergen Current is investigated, based on data from an array of current meter moorings along 78.83oN, across the deeper (1000-2400 m) section of the continental slope west of Svalbard. ... -
Barotropic instability in the West Spitsbergen Current
(Peer reviewed; Journal article, 2010-07-24)Barotropic instability in the shoreward branch of the West Spitsbergen Current is investigated on the basis of data from an array of current meter moorings along 78.83°N, across the upper continental slope and shelf break ... -
