Potential impact of tropopause sharpness on the structure and strength of the general circulation
(Journal article; Peer reviewed, 2022)The wintertime extratropical general circulation may be viewed as being primarily governed by interactions between Rossby waves and the background flow. These Rossby waves propagate vertically and meridionally away from ... -
Potential Influences of Volcanic Eruptions on Future Global Land Monsoon Precipitation Changes
(Journal article; Peer reviewed, 2021)The global monsoon system is of exceptional socioeconomic importance owing to its impacts on two-thirds of the globe’s population. Major volcanic eruptions strongly influence global land monsoon (GLM) precipitation change. ... -
Pre-bloom dynamics of the Subpolar North Atlantic microbial food web
(Master thesis, 2013-02-18)The aim of this study was to investigate the microbial planktonic food web in the pre- bloom period of the Subpolar North Atlantic Ocean. Through repeated visits to the Icelandic Basin, Norwegian Basin, and on the Shetland ... -
Predictable Variations of the Carbon Sinks and Atmospheric CO2 Growth in a Multi-Model Framework
(Journal article; Peer reviewed, 2021)Inter-annual to decadal variability in the strength of the land and ocean carbon sinks impede accurate predictions of year-to-year atmospheric carbon dioxide (CO2) growth rate. Such information is crucial to verify the ... -
Prediction of Harmful Algae Blooms Impacting Shellfish Farms in Norway
(Doctoral thesis, 2023-11-30)Skadelig algeoppblomstring (HAB) forårsaker alvorlig skade på økosystemet og menneskers helse, samt økonomiske konsekvenser for skalldyr og oppdrettsanlegg. Utviklingen av HABs prediksjonsmodeller har blitt økenende populart ... -
Predictive Analysis of Machine Learning Schemes in Forecasting of Offshore Wind
(Journal article; Peer reviewed, 2020)High variability of wind in the farm areas causes a drastic instability in the energy markets. Therefore, precise forecast of wind speed plays a key role in the optimal prediction of offshore wind power. In this study, we ... -
Predictive Capability of WRF Cycling 3DVAR: LiDAR Assimilation at FINO1
(Journal article; Peer reviewed, 2021)In this study, we assess tentatively the predictive capability of the Weather Research and Forecasting (WRF) model and its Three-Dimensional Variational (3DVAR) system. We study the impact of LiDAR data assimilation on ... -

Preformed Properties for Marine Organic Matter and Carbonate Mineral Cycling Quantification
(Journal article; Peer reviewed, 2021)We estimate preformed ocean phosphate, nitrate, oxygen, silicate, and alkalinity by combining a reconstruction of ventilation pathways in the ocean interior with estimates of submixed layer properties. These new preformed ... -
Preliminary results of the NORCOWE Direct Covariance Flux System for Ship based measurements
(Peer reviewed; Journal article, 2013)To cover the increased demand of renewable energy the development of offshore wind turbines that can be placed in deep water has started. Model results from Sullivan et al. [2] indicate that the ocean has the ability to ... -
Present and future drivers of Arctic sea ice variability
(Doctoral thesis, 2024-03-07)Havisdekket i Arktis har blitt gradvis redusert de siste tiårene. Isdekket varierer likevel betydelig fra år til år, og fra tiår til tiår på grunn av naturlige (interne) variasjoner i klimasystemet. Slike interne variasjoner ... -
Present Temperature, Precipitation, and Rain‐on‐Snow Climate in Svalbard
(Journal article; Peer reviewed, 2020)The Svalbard Archipelago has undergone rapid warming in the recent decades leading to warmer and wetter winter conditions. This study relates the present (2013–2018) 2 m temperature, precipitation, and rain-on-snow (ROS) ... -
Prevailing Surface Wind Direction during Air-Sea Heat Exchange
(Peer reviewed; Journal article, 2019)While the climatological-mean sensible and latent heat fluxes are remarkably well described using climatological-mean fields in the bulk flux formulas, this study shows that a significant fraction of the climatological-mean ... -
Processing of sonic anemometer measurements for offshore wind turbine applications
(Peer reviewed; Journal article, 2019)Quality assured measurements from offshore masts may provide valuable information of the characteristics of the offshore wind field, which is of high relevance for simulations of offshore wind turbines' dynamic response. ... -
Productivity in the Barents Sea - Response to recent climate variability
(Peer reviewed; Journal article, 2014-05-01)The temporal and spatial dynamics of primary and secondary biomass/production in the Barents Sea since the late 1990s are examined using remote sensing data, observations and a coupled physical-biological model. Field ... -
Projected changes in significant wave height toward the end of the 21st century: Northeast Atlantic
(Peer reviewed; Journal article, 2017-04)Wind field ensembles from six CMIP5 models force wave model time slices of the northeast Atlantic over the last three decades of the 20th and the 21st centuries. The future wave climate is investigated by considering the ... -
Projected pH reductions by 2100 might put deep North Atlantic biodiversity at risk
(Peer reviewed; Journal article, 2014-12-11)This study aims to evaluate the potential for impacts of ocean acidification on North Atlantic deep-sea ecosystems in response to IPCC AR5 Representative Concentration Pathways (RCPs). Deep-sea biota is likely highly ... -
Projecting Spring Consecutive Rainfall Events in the Three Gorges Reservoir based on Treble-Nested dynamical downscaling
(Journal article; Peer reviewed, 2024)Spring consecutive rainfall events (CREs) are key triggers of geological hazards in the Three Gorges Reservoir area (TGR), China. However, previous projections of CREs based on the direct outputs of global climate models ... -
Projecting Wintertime Newly Formed Arctic Sea Ice through Weighting CMIP6 Model Performance and Independence
(Journal article; Peer reviewed, 2024)Precipitous Arctic sea-ice decline and the corresponding increase in Arctic open-water areas in summer months give more space for sea-ice growth in the subsequent cold seasons. Compared to the decline of the entire Arctic ... -
