The Effect of Sea Surface Temperature Fronts on Atmospheric Frontogenesis
(Journal article; Peer reviewed, 2021)It is thought that the sensible heat fluxes associated with sea surface temperature (SST) fronts can affect the genesis and evolution of atmospheric fronts. An analytic model is developed and used to explore this idea. The ... -
Effect of substrate type and pellet age on the resuspension of Atlantic salmon faecal material
(Journal article; Peer reviewed, 2020)The influence of substrate type and particle age on the remobilization of settled Atlantic salmon Salmo salar faecal material was studied through a set of controlled experiments in horizontal flow flumes, simulating different ... -
The effect of vertical mixing on the horizontal drift of oil spills
(Peer reviewed; Journal article, 2018)Vertical and horizontal transport mechanisms for marine oil spills are investigated using numerical model simulations. To realistically resolve the 3-D development of a spill on the ocean surface and in the water column, ... -
The effect of wind speed products and wind speed-gas exchange relationships on interannual variability of the air-sea CO2 gas transfer velocity
(Journal article, 2005)The lack of a firm relationship between wind speed (U10) and gas transfer velocity (k) is considered to be one of the factors that hinders accurate quantification of interannual variations of ocean–atmosphere CO2 fluxes. ... -
Effects of altitude and aerosol on UV radiation
(Journal article; Peer reviewed, 2006-01-10)Measurements of erythemally weighted UV radiation during about 600 days at different sites in Bolivia and Germany ranging from 550 to 5240 m above sea level have been used to derive the altitude effect AE under cloud-free ... -
Effects of diapycnal and isopycnal mixing on the ventilation of CFCs in the North Atlantic in an isopycnic coordinate OGCM
(Peer reviewed; Journal article, 2003)Simulated distributions of the chlorofluorocarbons CFC-11 and CFC-12 are used to examine the ventilation of the North Atlantic Ocean in a global version of the Miami Isopycnic Coordinate Ocean Model (MICOM). Three simulations ... -
Effects of Eulerian current, Stokes drift and wind while simulating surface drifter trajectories in the Baltic Sea
(Journal article; Peer reviewed, 2023)The simulation of Lagrangian drift is an important task in applications such as dispersion of pollutants, larvae and search and rescue activities. In this study, the Eulerian current, Stokes drift and wind effect on the ... -
Effects of negative shear on loads for a 15 MW offshore wind turbine during low-level jet events
(Journal article; Peer reviewed, 2023)Wind turbines are more often interacting with the negative shear region of a low-level jet due to increasing turbine sizes. However, the effects of negative shear on wind turbines are not sufficiently studied, particularly ... -
Effects of sea-ice and biogeochemical processes and storms on under-ice water fCO2 during the winter-spring transition in the high Arctic Ocean: Implications for sea-air CO2 fluxes
(Peer reviewed; Journal article, 2017-07)We performed measurements of carbon dioxide fugacity (fCO2) in the surface water under Arctic sea ice from January to June 2015 during the Norwegian young sea ICE (N-ICE2015) expedition. Over this period, the ship drifted ... -
Effects of simulated natural variability on Arctic temperature
(Journal article, 2005-09-23)A five-member ensemble with a coupled atmospheresea ice-ocean model is used to examine the effects of natural variability on climate projections for the Arctic. The individual ensemble members are initialized from a 300 ... -
Effects of solar irradiance forcing on the ocean circulation and sea-ice in the North Atlantic in an isopycnic coordinate ocean general circulation model
(Peer reviewed; Journal article, 2004)The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ... -
Effects of solar irradiance forcing on the ocean circulation and sea-ice in the North Atlantic in an isopycnic coordinate ocean general circulation model
(Tellus;56A(2), Journal article, 2004-03)The sensitivity of the ocean circulation to changes in solar irradiance is examined using an isopycnic coordinate, global ocean general circulation model (OGCM) coupled to a thermodynamic/dynamic sea-ice model. In the ... -
The effects of spatial and temporal variations in spawning on offspring survival in Northeast Arctic cod
(Journal article; Peer reviewed, 2024)Climate change and harvesting result in temporal and spatial changes and variability in spawning, and thus in offspring ambient drift conditions. As a result, variable survival of offspring and thereby in recruitment are ... -
Effects of wave-induced processes in a coupled wave-ocean model on particle transport simulations
(Journal article; Peer reviewed, 2021)This study investigates the effects of wind–wave processes in a coupled wave–ocean circulation model on Lagrangian transport simulations. Drifters deployed in the southern North Sea from May to June 2015 are used. The ... -

An efficient training scheme for supermodels
(Peer reviewed; Journal article, 2017-06-28)Weather and climate models have improved steadily over time as witnessed by objective skill scores, although significant model errors remain. Given these imperfect models, predictions might be improved by combining them ... -
Ein enkel orografisk nedbørsmodell for Vestlandet
(Master thesis, 2011)I denne oppgåva er det undersøkt om ein enkel orografisk nedbørsmodell vil kunne gje gode estimat for nedbøren på Vestlandet. Ein del av oppgåva har vore å finne ut om ein slik modell er eit eigna verktøy til å forklare ... -
Ekstremverdianalyse av nedbør og oppdatering av intensitet - varighet - frekvenskurver i Bergen Kommune
(Master thesis, 2016-06-14)Bergen er en by på vestkysten av Norge kjent for høyre årlige nedbørsmengder og mange regndager.På grunn av dette har en i Bergen en lang historie i håndtering av store nedbørsmengder. Dette har en lykkes godt med så langt, ... -
The El Niño effect on Ethiopian summer rainfall
(Journal article; Peer reviewed, 2017)While El Niño is known to cause failure of Kiremt (boreal summer) rainfall in Ethiopia, the mechanisms are not fully understood. Here we use the ECHAM5 Atmospheric General Circulation Model to investigate the physical link ...
