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 ... -
Electron Density Depletion Region Observed in the Polar Cap Ionosphere
(Journal article; Peer reviewed, 2021)This paper presents and discusses electron density depletion regions observed with the incoherent scatter EISCAT Svalbard Radar (ESR) located at 75.43°N geomagnetic latitude. The data include several decades of measurements, ... -
The Emergence of the North Icelandic Jet and Its Evolution from Northeast Iceland to Denmark Strait
(Peer reviewed; Journal article, 2019)The North Icelandic Jet (NIJ) is an important source of dense water to the overflow plume passing through Denmark Strait. The properties, structure, and transport of the NIJ are investigated for the first time along its ... -
En eksperimentell oppgave på legeringer av silisium og jern
(Master thesis, 2023-06-06)Silisium og legeringer med silisium er viktige materialer innen forskjellige industrier og brukes blant annet som tilsetningsstoff. I flere typer industri brukes slike legerin- ger i form av pulver, både for enklere transport ... -
En hydrografisk undersøkelse i Grønlandshavet i april 1980
(Master thesis, 1983)I april 1980 blei det foretatt et tokt med M/S ‘Polarsirkel’ til de sentrale delene av Grønlandshavet, hvor i alt 89 CTD-stasjoner blei tatt. De hydrografiske dataene fra dette toktet har i denne hovedfagsoppgaven blitt ... -
Enabling the direct comparison of high-resolution precipitation observations with operational weather prediction model output
(Master thesis, 2022-06-01)Precipitation characteristics is expected to change in the future, as an effect of global climate change. High-intensity precipitation will become a more frequent concern in some areas of the world. The rapid changes and ... -
Energy Storage in the Distribution Grid
(Master thesis, 2017-12-23)The implementation of distributed energy storage will play a vital role in the Smart Grid of the future, which is the merging of IT and the electrical power grid. With the increasing penetration of distributed energy ... -
Enhancing Seasonal Forecast Skills by Optimally Weighting the Ensemble from Fresh Data
(Journal article; Peer reviewed, 2023)Dynamical climate predictions are produced by assimilating observations and running ensemble simulations of Earth system models. This process is time consuming and by the time the forecast is delivered, new observations ... -
En enkel gressvekstmodell utprøvd på Island og i Norge
(Master thesis, 2001) -
Ensemble-based data assimilation and forecasting with an eddy-resolving model of the Gulf of Mexico
(Doctoral thesis, 2008-09-12) -
ENSO teleconnections in terms of non-NAO and NAO atmospheric variability
(Journal article; Peer reviewed, 2023)The validity of the long-held understanding or assumption that El Niño-Southern Oscillation (ENSO) has a remote influence on the North Atlantic Oscillation (NAO) in the January–February–March (JFM) months has been questioned ... -
An Equatorial–Extratropical Dipole Structure of the Atlantic Niño
(Peer reviewed; Journal article, 2016)Equatorial Atlantic variability is dominated by the Atlantic Niño peaking during the boreal summer. Studies have shown robust links of the Atlantic Niño to fluctuations of the St. Helena subtropical anticyclone and Benguela ... -
ESD Reviews: Climate feedbacks in the Earth system and prospects for their evaluation
(Peer reviewed; Journal article, 2019)Earth system models (ESMs) are key tools for providing climate projections under different scenarios of human-induced forcing. ESMs include a large number of additional processes and feedbacks such as biogeochemical cycles ... -
Estimating a mean transport velocity in the marginal ice zone using ice-ocean prediction systems
(Journal article; Peer reviewed, 2022)Understanding the transport of objects and material in the marginal ice zone (MIZ) is critical for human operations in polar regions. This can be the transport of pollutants, such as spilled oil, or the transport of objects, ... -
Estimating fin whale distribution from ambient noise spectra using Bayesian inversion
(Master thesis, 2015-06-01)Passive acoustic monitoring is increasingly used to study the distribution and migration of marine mammals. Marine mammal vocalizations are transient sounds, but the combined sound energy of a population continuously ... -
Estimating global radiation at ground level from satellite images

Estimation of groundwater storage loss for the Indian Ganga Basin using multiple lines of evidence
(Journal article; Peer reviewed, 2023)We used remote sensing data, field observations and numerical groundwater modelling to investigate long-term groundwater storage losses in the regional aquifer of the Ganga Basin in India. This comprised trend analysis for ... -
Estimation of Ocean Biogeochemical Parameters in an Earth System Model Using the Dual One Step Ahead Smoother: A Twin Experiment
(Journal article; Peer reviewed, 2022)Ocean biogeochemical (BGC) models utilise a large number of poorly-constrained global parameters to mimic unresolved processes and reproduce the observed complex spatio-temporal patterns. Large model errors stem primarily ...
