Long-term changes in stratification and convection in the Nordic Seas : An observational perspective
(Doctoral thesis, 2025-01-21)I løpet av de siste tiårene har de Nordiske Hav gjennomgått en endring mot høyere temperatur og lavere tetthet. I Grønlandshavet ble den tyngste vannmassen i de Nordiske Hav dannet gjennom konveksjon som nådde helt til ... -
IEA Wind Task 49: Reference Site Conditions for Floating Wind Arrays
(Journal article; Peer reviewed, 2024)The commercial-scale deployment of floating offshore wind (FOW) projects is expected to take place in a diverse range of sites that may differ significantly from existing fixed-bottom projects. FOW farms are particularly ... -
Assessment of wind-damage relations for Norway using 36 years of daily insurance data
(Journal article; Peer reviewed, 2024)Extreme winds are by far the largest contributor to Norway’s insurance claims related to natural hazards. The predictive skills of four different damage functions are assessed for Norway at the municipality and national ... -
Projections of windstorms damages under changing climate and demography for Norway
(Journal article, 2024)Windstorms cause severe damages and are the dominant natural hazard responsible for insurance payouts in Norway. Using future wind speeds from twenty bias corrected regional climate model simulations from EURO-CORDEX and ... -
StormRisk: Linking Norwegian windstorms and damage, future risk and the feasibility of impact based forecasting
(Doctoral thesis, 2025-01-14)Vindstormer er blant de mest signifikante naturfarene i Norge, og kan påføre skade på infrastruktur og eiendom, inkludert boliger, industribygg og kraftlinjer. Pålitelige risikoanalyser av vindstormer og nøyaktige værmeldinger ... -
Storm-Driven Warm Inflow Toward Ice Shelf Cavities—An Idealized Study of the Southern Weddell Sea Continental Shelf System
(Journal article; Peer reviewed, 2024)Sudden peaks in south-westward wind strength (storms) have been observed to drive pulses of enhanced southward currents on the continental shelf east of the Filchner Trough. However, the link between wind and southward ... -
Funeral directors’ experiences during the COVID-19 pandemic: a mixed method study
(Journal article; Peer reviewed, 2024)To investigate the impact of the COVID-19 pandemic on death rituals among funeral directors (FDs) (N = 134), we administered a questionnaire and conducted three focus group interviews (N = 21). The merged results showed ... -
SAMURAI - Development, Test and Validation of an Airborne Sonic Anemometer
(Doctoral thesis, 2024-12-16)Fremskritt innen forskning på atmosfærens grenselag (ABL) er avhengig av en nøyaktig beskrivelse av turbulens i luften. Den veletablerte metoden for å undersøke turbulens involverer høy-frekvente in-situ observasjoner med ... -
Bias correction of operational storm surge forecasts using Neural Networks
(Journal article; Peer reviewed, 2024)Storm surges can give rise to extreme floods in coastal areas. The Norwegian Meteorological Institute (MET Norway) produces 120 h regional operational storm surge forecasts along the coast of Norway based on the Regional ... -
Mussel reefs promote taxonomic biodiversity and host a unique assemblage of mobile marine fauna in a coastal area of poor ecological status
(Journal article; Peer reviewed, 2024)Coastal ecosystems worldwide face increasing anthropogenic pressures, with implications for the local ecological status and biodiversity. Using a temperate coastal ecosystem in poor ecological condition, this study revealed ... -
Hybrid covariance super-resolution data assimilation
(Journal article; Peer reviewed, 2024)The super-resolution data assimilation (SRDA) enhances a low-resolution (LR) model with a Neural Network (NN) that has learned the differences between high and low-resolution models offline and performs data assimilation ... -
Projecting Wintertime Newly Formed Arctic Sea Ice through Weighting CMIP6 Model Performance and Independence
(Journal article; Peer reviewed, 2024)Precipitous Arctic sea-ice decline and the corresponding increase in Arctic open-water areas in summer months give more space for sea-ice growth in the subsequent cold seasons. Compared to the decline of the entire Arctic ... -
Boosting effect of strong western pole of the Indian Ocean Dipole on the decay of El Niño events
(Journal article; Peer reviewed, 2024)The Indian Ocean Basin (IOB) mode is believed to favor the decay of El Niño via modulating the zonal wind anomalies in the western equatorial Pacific, while the contribution of the Indian Ocean Dipole (IOD) mode to the ... -
Thermodynamic and dynamic contributions to the abrupt increased winter Arctic sea ice growth since 2008
(Journal article; Peer reviewed, 2024)The area of Arctic winter sea ice growth (WSIG) has expanded dramatically since winter 2008. Yet the thermodynamic and dynamic contributions to the abrupt increase in WSIG remain unclear. Here using an ice concentration ... -
Upstream influence of midlatitude jet stream biases in boreal summer
(Journal article; Peer reviewed, 2024)Climate models exhibit biases in the mean state and in variability across different regions of the Earth. For example, atmosphere-only models have a poleward bias in summertime jet streams across the Northern Hemisphere ... -
Post-depositional modification on seasonal-to-interannual timescales alters the deuterium-excess signals in summer snow layers in Greenland
(Journal article; Peer reviewed, 2024)We document the isotopic evolution of near-surface snow at the East Greenland Ice Core Project (EastGRIP) ice core site in northeast Greenland using a time-resolved array of 1 m deep isotope (δ18O, δD) profiles. The snow ... -
An emerging pathway of Atlantic Water to the Barents Sea through the Svalbard Archipelago: Drivers and variability
(Journal article; Peer reviewed, 2024)The Barents Sea, an important component of the Arctic Ocean, is experiencing changes in its ocean currents, stratification, sea ice variability, and marine ecosystems. Inflowing Atlantic Water (AW) is a key driver of these ... -
Linking Future Precipitation Changes to Weather Features in CESM2-LE
(Journal article; Peer reviewed, 2024)Weather features, such as extratropical cyclones, atmospheric rivers (ARs), and fronts, contribute to substantial amounts of precipitation globally and are associated with different precipitation characteristics. However, ... -
Experimental Characterization of Propeller-Induced Flow (PIF) below a Multi-Rotor UAV
(Journal article; Peer reviewed, 2024-02-20)The availability of multi-rotor UAVs with lifting capacities of several kilograms allows for a new paradigm in atmospheric measurement techniques, i.e., the integration of research-grade sonic anemometers for airborne ... -
Advancing annual global mean surface temperature prediction to 2 months lead using physics based strategy
(Journal article; Peer reviewed, 2024)Interannual global mean surface temperature (GMST) forecast provides critical insights into the economic and societal implications of climate variability. The pronounced GMST elevation in 2023–2024 indicates that the Earth ...
