Towards a more saline North Atlantic and a fresher Arctic under global warming
(Peer reviewed; Journal article, 2006-11-14)Most atmosphere-ocean general circulation models (GCMs) forced with increasing greenhouse gas concentrations predict enhanced atmospheric moisture transports to the high northern latitudes. Together with melting of Arctic ... -
Towards end-to-end (E2E) modelling in a consistent NPZD-F modelling framework (ECOSMO E2E_v1.0): Application to the North Sea and Baltic Sea
(Peer reviewed; Journal article, 2019-05-06)Coupled physical–biological models usually resolve only parts of the trophic food chain; hence, they run the risk of neglecting relevant ecosystem processes. Additionally, this imposes a closure term problem at the respective ... -
Towards quantifying the increasing role of oceanic heat in sea ice loss in the new Arctic
(Peer reviewed; Journal article, 2015)The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together with acknowledged impacts on other components of the Earth system, has led to the term “the new Arctic.” Global coupled climate ... -
Towards Retrieving Reliable Ocean Surface Currents in the Coastal Zone From the Sentinel-1 Doppler Shift Observations
(Journal article; Peer reviewed, 2022)Recent developments on calibration and partitioning of the signal between the wave and current contributions significantly improve the accuracy of geophysical retrievals from Sentinel-1 Synthetic Aperture Radar-based Doppler ... -
Tracer-derived transit time of the waters in the eastern Nordic Seas
(Peer reviewed; Journal article, 2005-08-25)The spatial-temporal distribution of the anthropogenic radionuclide 137Cs originating from nuclear bomb testing and the Sellafield reprocessing plant in the Irish Sea is simulated using a global version of the Miami Isopycnic ... -
Tracing Lower Cretaceous organic-rich units across the SW Barents Shelf
(Journal article; Peer reviewed, 2022)On the Barents Shelf, the northernmost and least explored hydrocarbon province of the Norwegian Continental Shelf, Upper Jurassic organic-rich shales have traditionally been given most attention as these represent the most ... -
Tracing the Imprint of River Runoff Variability on Arctic Water Mass Transformation
(Peer reviewed; Journal article, 2019-01-14)The Arctic Ocean receives a net freshwater input from land and from the atmosphere. This flux of freshwater, along with net surface heat loss, acts to transform the water mass properties of inflowing Atlantic and Pacific ... -
Tracking Summer Extra-Tropical Storms: A Climatological Overview and Variability in the Northern Hemisphere
(Master thesis, 2006-05-04) -
Training a supermodel with noisy and sparse observations: A case study with CPT and the synch rule on SPEEDO-v.1
(Journal article; Peer reviewed, 2022)As an alternative to using the standard multi-model ensemble (MME) approach to combine the output of different models to improve prediction skill, models can also be combined dynamically to form a so-called supermodel. The ... -
Training of supermodels - in the context of weather and climate forecasting
(Doctoral thesis, 2021-02-08)Given a set of imperfect weather or climate models, predictions can be improved by combining the models dynamically into a so called `supermodel'. The models are optimally combined to compensate their individual errors. ... -
Transient response of the Atlantic Meridional Overturning Circulation to enhanced freshwater input to the Nordic Seas–Arctic Ocean in the Bergen Climate Model
(Tellus A;56(4), Journal article, 2004-07-09)The transient response of the climate system to anomalously large freshwater input to the high latitude seas is examined using the newly developed Bergen Climate Model. A 150-yr twin-experiment has been carried out, ... -
Transientstabilitet-implementering ved BESS for offshore mikronett i øymodus
(Master thesis, 2022-06-01)Konvensjonelle mikronett har tradisjonelt sikret spenning- og frekvensstabilitet med spinning-reserve fra roterende maskiner ved forstyrrelser i nettet. En økende andel av ikke-roterende energiproduksjon påvirker kraftsystemers ... -
Transitioning remote Arctic settlements to renewable energy systems – A modelling study of Longyearbyen, Svalbard
(Journal article; Peer reviewed, 2020)As transitioning away from fossil fuels to renewable energy sources comes on the agenda for a range of energy systems, energy modelling tools can provide useful insights. If large parts of the energy system turns out to ... -
Transport of inorganic carbon through, within, and below the ocean surface
(Doctoral thesis, 2011-03-11)Human emissions of CO2 through the burning of fossil fuel, cement production, and land use change have increased the atmospheric CO2 concentration by 39 % since 1750. Without the large uptake of anthropogenic CO2 by the ... -
Transport Upscaling in Porous Media
(Master thesis, 2014-06-02)Numerical models are important for modeling what happens in porous media. In this thesis we will simulate the heat transport in geothermal reservoirs. Because these reservoirs are usually quite large, we will make a model ... -
Trapped tidal currents generate freely propagating internal waves at the Arctic continental slope
(Journal article; Peer reviewed, 2023)Energetic tidal currents in the Arctic play an important role in local mixing processes, but they are primarily confined to the shelves and continental slopes due to topographic trapping north of their critical latitude. ... -
Trends and drivers in global surface ocean pH over the past 3 decades
(Peer reviewed; Journal article, 2015-03-02)We report global long-term trends in surface ocean pH using a new pH data set computed by combining fCO2 observations from the Surface Ocean CO2 Atlas (SOCAT) version 2 with surface alkalinity estimates based on temperature ... -
Trends and internal variability in Brazilian hydropower catchments
(Master thesis, 2023-06-01)Hydropower is a major energy source in Brazil, and long-term hydropower production planning is crucial both for maintaining energy and water security in the country. The amount of water that is available to electricity ... -
Trends in extreme precipitation and the influence by meteorological parameters following the RCP8.5 scenario over 2 catchments in India
(Master thesis, 2015-06-02)The Historical1 simulation (1960-2000) and the RCP8.5 scenario (2060-2100) from the NorESM are used to investigate trends in extreme precipitation, as well as the impact from vertical velocity, specific humidity, divergence ... -
