Causes of the large warm bias in the Angola–Benguela Frontal Zone in the Norwegian Earth System Model
(Journal article; Peer reviewed, 2018)We have investigated the causes of the sea surface temperature (SST) bias in the Angola–Benguela Frontal Zone (ABFZ) of the southeastern Atlantic Ocean simulated by the Norwegian Earth System Model (NorESM). Similar to ... -
Certain aspects of high latitude climate variability

Challenges in seismic hazard assessment: Analyses of ground motion modelling and seismotectonic sources
(Doctoral thesis, 2006-06-21)Seismic hazard assessment has an important societal impact in describing levels of ground motions to be expected in a given region in the future. Challenges in seismic hazard assessment are closely associated with the fact ... -
Changes in atmospheric variability in a glacial climate and the impacts on proxy data: a model intercomparison
(Peer reviewed; Journal article, 2009-09-11)Using four different climate models, we investigate sea level pressure variability in the extratropical North Atlantic in the preindustrial climate (1750 AD) and at the Last Glacial Maximum (LGM, 21 kyrs before present) ... -
Changes in the properties and distribution of the intermediate and deep waters in the Fram Strait
(Peer reviewed; Journal article, 2012-04)The Fram Strait is the only deep connection between the Arctic Ocean and the Nordic Seas (Greenland, Iceland, and Norwegian Seas), with a sill depth of approximately 2600 m. Consequently, observations from this area reflect ... -
Characterisation of Single Wind Turbine Wakes with Static and Scanning WINTWEX-W LiDAR Data
(Peer reviewed; Journal article, 2015)With further development of LiDAR technology wake measurements by use of LiDAR became of common interest in the wind energy community. To study new measurement strategies of scanning and nacelle LiDARs, in combination with ... -
Characterising the local and intense water cycle during a cold air outbreak in the Nordic Seas
(Journal article; Peer reviewed, 2018)Air masses in marine cold air outbreaks (CAOs) at high latitudes undergo a remarkable diabatic transformation because of the uptake of heat and moisture from the ocean surface, and the formation of precipitation. In this ... -
Characteristics and Transformation of Pacific Winter Water on the Chukchi Sea Shelf in Late Spring
(Peer reviewed; Journal article, 2019)Data from a late spring survey of the northeast Chukchi Sea are used to investigate various aspects of newly ventilated winter water (NVWW). More than 96% of the water sampled on the shelf was NVWW, the saltiest (densest) ... -
Characteristics of Cold-Air Outbreak Events and Associated Polar Mesoscale Cyclogenesis over the North Atlantic Region
(Journal article; Peer reviewed, 2021)Equatorward excursions of cold polar air masses into ice-free regions, so-called Cold Air Outbreaks (CAO), are frequently accompanied by the development of severe mesoscale weather features. Focusing on two key regions, ... -
Characteristics of cyclones following different pathways in the Gulf Stream region
(Journal article; Peer reviewed, 2021)The Northwest Atlantic is a region of strong temperature gradients and hence is a favourable location for wintertime cyclone intensification co-located with the storm track. The temperature gradient is associated with both ... -
Characterization of Terrain-Induced Turbulence by Large-Eddy Simulation for Air Safety Considerations in Airport Siting
(Journal article; Peer reviewed, 2022)Topography-induced turbulence poses a potential hazard for aviation safety, in particular during the final approach and landing. In this context, it is essential to assure that the impact of topography-induced turbulence ... -
Characterization of the atmospheric environment during extreme precipitation events associated with atmospheric rivers in Norway - Seasonal and regional aspects
(Journal article; Peer reviewed, 2021)Extreme precipitation events in Norway in all seasons are often linked to atmospheric rivers (AR). We show that during the period 1979–2018 78.5% of the daily extreme precipitation events in Southwestern Norway are linked ... -
Characterization of the coastal marine atmospheric boundary layer (MABL) for wind energy applications
(Master thesis, 2013-06-03)The main problem for the characterization of marine atmospheric boundary layer is the lack of available offshore measurements in relevant altitude range up to 200 m. Remote sensing meteorological instruments such as LIDARs ... -
Characterization of the SUMO Turbulence Measurement System for Wind Turbine Wake Assessment
(Peer reviewed; Journal article, 2014)The remotely piloted aircraft system (RPAS) SUMO (Small Unmanned Meteorological Observer) has been equipped with a miniaturized 5-hole probe sensor system for measurement of the 3-dimensional flow vector with a temporal ... -
Characterization of turbulence in wind turbine wakes under different stability conditions from static Doppler LiDAR measurements
(Peer reviewed; Journal article, 2017-03-05)Wake characteristics are of great importance for wind park performance and turbine loads. While wind tunnel experiments provided a solid base for the basic understanding of the structure and dynamics of wind turbine wakes, ... -
Characterization of Wind-Sea- and Swell-Induced Wave Energy along the Norwegian Coast
(Journal article; Peer reviewed, 2020)The necessity to reduce CO2 emissions in combination with the rising energy demand worldwide makes the extensive use of renewable energy sources increasingly important. To that end, countries with long coastlines, such as ... -
Characterizing Atlantic interhemispheric teleconnection established by South American monsoon in austral summer
