A mechanical energy budget for the North Sea
(Journal article, 2004-06-29)A three-dimensional baroclinic numerical model is used to quantify the components of the mechanical energy budget for a semi-enclosed sea, the North Sea. As anticipated, tidal energy is the largest supplier of mechanical ... -
Mechanisms affecting the transport of early stages of Norwegian Coastal Cod - a fjord study
(Master thesis, 2008-05-30)The fjord system of Sørfolda and Nordfolda situated in northern Norway is used in a model study. Particularly to explore the mechanisms causing separation and mixing of eggs from Arcto-Norwegian Cod (ANC) and Norwegian ... -
Mechanisms and pathways of ocean heat anomalies in the Arctic-Atlantic region
(Doctoral thesis, 2020-12-10)Along the Atlantic water pathway, from the Gulf Stream in the south to the Arctic Ocean in the north, variability in ocean heat content is pronounced on interannual to decadal time scales. Ocean heat anomalies in this ... -
Mechanisms for decadal scale variability in a simulated Atlantic Meridional Overturning Circulation
(Peer reviewed; Journal article, 2011-06-25)Variability in the Atlantic Meridional Overturning Circulation (AMOC) has been analysed using a 600-year pre-industrial control simulation with the Bergen Climate Model. The typical AMOC variability has amplitudes of 1 ... -
Mechanisms of decadal North Atlantic climate variability and implications for the recent cold anomaly
(Journal article; Peer reviewed, 2021)Decadal sea surface temperature (SST) fluctuations in the North Atlantic Ocean influence climate over adjacent land areas and are a major source of skill in climate predictions. However, the mechanisms underlying decadal ... -
Mechanisms of Ocean Heat Anomalies in the Norwegian Sea
(Peer reviewed; Journal article, 2019-04)Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales. These ocean heat anomalies are known to influence Arctic sea ice extent, marine ecosystems, and continental ... -
Mechanisms of offshore solid and liquid freshwater flux from the East Greenland Current
(Journal article; Peer reviewed, 2024)The mechanisms that control the export of freshwater from the East Greenland Current, in both liquid and solid form, are explored using an idealized numerical model and scaling theory. A regional, coupled ocean–sea ice ... -
Mechanisms of regional winter sea-ice variability in a warming arctic
(Journal article; Peer reviewed, 2021)The Arctic winter sea ice cover is in retreat overlaid by large internal variability. Changes to sea ice are driven by exchange of heat, momentum, and freshwater within and between the ocean and the atmosphere. Using a ... -
The mechanisms that determine the response of the Northern Hemisphere’s stationary waves to North American Ice Sheets
(Peer reviewed; Journal article, 2019-07-01)Stationary waves describe the persistent meanders in the west–east flow of the extratropical atmosphere. Here, changes in stationary waves caused by ice sheets over North America are examined and the underlying mechanisms ... -
Mechanisms underlying recent Arctic atlantification
(Journal article; Peer reviewed, 2020-06-20)Recent warming and reduced sea ice concentrations in the Atlantic sector of the Arctic Ocean are the main signatures of ongoing Arctic “Atlantification.” The mechanisms driving the warming trends are nevertheless still ... -
Melting of Northern Greenland during the last interglaciation
(Peer reviewed; Journal article, 2012-11-05)Using simulated climate data from the comprehensive coupled climate model IPSL CM4, we simulate the Greenland ice sheet (GrIS) during the Eemian interglaciation with the three-dimensional ice sheet model SICOPOLIS. The ... -
Meridional and vertical variations of the water vapour isotopic composition in the marine boundary layer over the Atlantic and Southern Ocean
(Journal article; Peer reviewed, 2020)Stable water isotopologues (SWIs) are useful tracers of moist diabatic processes in the atmospheric water cycle. They provide a framework to analyse moist processes on a range of timescales from large-scale moisture transport ... -
Meridional Ocean Carbon Transport
(Journal article; Peer reviewed, 2020)The ocean's ability to take up and store CO2 is a key factor for understanding past and future climate variability. However, qualitative and quantitative understanding of surface-to-interior pathways, and how the ocean ... -
Mesoscale Eddies Are Oases for Higher Trophic Marine Life
(Peer reviewed; Journal article, 2012-01-17)Mesoscale eddies stimulate biological production in the ocean, but knowledge of energy transfers to higher trophic levels within eddies remains fragmented and not quantified. Increasing the knowledge base is constrained ... -
The mesoscale eddy field in the Lofoten Basin from high-resolution Lagrangian simulations
(Journal article; Peer reviewed, 2021)Warm Atlantic-origin waters are modified in the Lofoten Basin in the Nordic Seas on their way toward the Arctic. An energetic eddy field redistributes these waters in the basin. Retained for extended periods, the warm ... -
Mesoscale Simulation of Open Cellular Convection: Roles of Model Resolutions and Physics Parameterizations
(Journal article; Peer reviewed, 2022)The Open Cellular Convection (OCC) associated with cold air outbreaks is a common phenomenon over the North Sea where a large number of wind parks are presented. Thus, reliable numerical simulations of OCC events have great ... -
Mesoscale variability study of the Agulhas Current from satellite radar altimetry and a high resolution model
(Master thesis, 2006-06)Towards understanding the dynamics and eddy evolving processes in the greater Agulhas Current system, a Hybrid Coordinate Ocean Model (HYCOM) system has been set up to simulation the ocean circulation around Southern Africa ... -
Meteorological conditions and cloud effects on surface radiation balance near Helheim glacier and Jakobshavn isbræ (Greenland)using ground-based observations.
(Journal article; Peer reviewed, 2021)The surface radiation budget is an essential component of the total energy exchange between the atmosphere and the Earth’s surface. Measurements of radiative fluxes near/on ice surfaces are sparse in the polar regions, ... -
Meteorological observations in tall masts for the mapping of atmospheric flow in Norwegian fjords
