Seasonality of coastal upwelling trends in the Mauritania-Senegalese region under RCP8.5 climate change scenario
(Journal article; Peer reviewed, 2023)The Mauritania-Senegalese upwelling region (MSUR), the southernmost region of the Canary current upwelling system, is well-known for its coastal productivity and the key role it plays in enriching the oligotrophic open ... -
Seasonality of Surface Chlorophyll in the Red Sea
(Master thesis, 2012-10-01)Although the understanding of the oceanography of the Red Sea has been developed over the last few decades, but we still have a little knowledge about the influences of the physical factors on the phytoplankton activity. ... -
Self-nested large-eddy simulations in PALM model system v21.10 for offshore wind prediction under different atmospheric stability conditions
(Journal article; Peer reviewed, 2023)Large-eddy simulation (LES) resolves large-scale turbulence directly and parametrizes small-scale turbulence. Resolving micro-scale turbulence, e.g., in wind turbine wakes, requires both a sufficiently small grid spacing ... -
Sensitivity analysis of the dynamic response of floating wind turbines
(Master thesis, 2018-08-23)Development of offshore wind turbines shows a clear shift from the fixed-bottom turbines to the floating turbines. The reason for such tendency is due to the fact that moving towards the deep ocean will substantially limit ... -
Sensitivity of Air-Sea Heat Exchange in Cold-Air Outbreaks to Model Resolution and Sea-Ice Distribution
(Journal article; Peer reviewed, 2021)Modeling air-sea interactions during cold air outbreaks poses a major challenge because of the vast range of scales and physical processes involved. Using the Polar WRF model, we investigate the sensitivity of downstream ... -
The sensitivity of marine-terminating glaciers to model parameters and geometry
(Master thesis, 2016-06-01)Greenland outlet glaciers are among the largest contributors to global sea level rise. With high velocities and calving rates, they discharge large amounts of glacial ice into the ocean. During the last two decades, the ... -
Sensitivity of remote sensing – derived phytoplankton productivity to mixed layer depth: Lessons from the carbon-based productivity model
(Peer reviewed; Journal article, 2009-10-01)Mixed layer depth (MLD) has long been recognized as having an important influence on underwater light budget and, thus, net primary productivity (NPP) of phytoplankton. The depth- and wavelength-integrated carbon-based ... -
Sensitivity of simulated wintertime Arctic atmosphere to vertical resolution in the ARPEGE/IFS model
(Journal article, 2008)The current state of the art general circulation models, including several of those used by the IPCC, show considerable disagreement in simulating present day high latitude climate. This is of major concern and reduces the ... -
Sensitivity of the dynamic response of a multimegawatt floating wind turbine to the choice of turbulence model
(Journal article; Peer reviewed, 2022)In the design of offshore wind turbines, it is important to make a realistic estimate of the wind load. This is particularly important for floating wind turbines, having natural frequencies in a frequency range where the ... -
Sensitivity of the marine biospheric Si cycle for biogeochemical parameter variations
(Peer reviewed; Journal article, 2003-09-06)A systematic quantitative assessment of the marine silicon cycle is presented, based on a prognostic coupled water column-sediment global biogeochemical ocean general circulation model (HAMOCC). The resulting tracer ... -
The sensitivity of the present day Atlantic meriodinal overturning circulation to freshwater forcing
(Peer reviewed; Journal article, 2003-09-09)Mounting evidence indicates that the Atlantic Meridional Overturning Circulation (AMOC) was strongly reduced during cold climate episodes in the past, possible due to freshwater influx from glacial melting. It is also ... -
Sensor movement correction for direct turbulence measurements in the marine atmospheric boundary layer
(Peer reviewed; Journal article, 2012)Understanding of the turbulent exchange processes between the ocean and the overlying atmosphere is essential for wind shear and turbulence structure of the Marine Atmospheric Boundary Layer (MABL). This is highly relevant ... -
Severe mesoscale weather events over the Nordic Seas: Numerical modelling and sensitivity experiments
(Doctoral thesis, 2011-06-22)The Nordic seas region, due to its unique geographical and climatological conditions, experiences a number of adverse mesoscale weather events that have proven fatal for human activities in the area. Most of these weather ... -
The "shallow-waterness" of the wave climate in European coastal regions
(Peer reviewed; Journal article, 2017-07-20)In contrast to deep water waves, shallow water waves are influenced by bottom topography, which has consequences for the propagation of wave energy as well as for the energy and momentum exchange between the waves and the ... -
Shelf/fjord exchange driven by coastal-trapped waves in the Arctic

A Ship-Based Characterization of Coherent Boundary-Layer Structures Over the Lifecycle of a Marine Cold-Air Outbreak
(Journal article; Peer reviewed, 2022)Convective coherent structures shape the atmospheric boundary layer over the lifecycle of marine cold-air outbreaks (CAOs). Aircraft measurements have been used to characterize such structures in past CAOs. Yet, aircraft ... -
Short-term solar and wind variability in long-term energy system models - A European case study
(Journal article; Peer reviewed, 2020)Integration of variable renewables such as solar and wind has grown at an unprecedented pace in Europe over the past two decades. As the share of solar and wind rises, it becomes increasingly important for long-term energy ... -
Shortwave absorptance in a tropical cloudy atmosphere: Reconciling calculations and observations
(Peer reviewed; Journal article, 2011-10-04)[1] The absorption of shortwave (SW) radiation by clouds is a topic surrounded by contradictory reports and controversy. Some studies have shown large discrepancies between observed SW absorption and absorption predicted ... -
Significant multidecadal variability in German wind energy generation
(Peer reviewed; Journal article, 2019-09-12)Wind energy has seen large deployment and substantial cost reductions over the last decades. Further ambitious upscaling is urgently needed to keep the goals of the Paris Agreement within reach. While the variability in ... -
