Dynamic properties of throat aurora revealed by simultaneous ground and satellite observations
(Peer reviewed; Journal article, 2017-03)Throat aurora is defined as south-north aligned auroral arcs equatorward of the dayside cusp aurora and was suggested to be the results of cold magnetospheric plasma interaction with magnetopause reconnection, but its ... -
Dynamic regulation of the transcription initiation landscape at single nucleotide resolution during vertebrate embryogenesis
(Peer reviewed; Journal article, 2013)Spatiotemporal control of gene expression is central to animal development. Core promoters represent a previously unanticipated regulatory level by interacting with cis-regulatory elements and transcription initiation in ... -
The dynamic response of offshore wind turbines and their sensitivity to wind field models
(Journal article; Peer reviewed, 2020)As the rotor diameter of offshore wind turbines increases, an improved understanding of the structure of the turbulent wind field approaching the rotor is important. Present standards for computing wind loads are resting ... -
Dynamic Susceptibility Contrast MRI May Contribute in Prediction of Stereotactic Radiosurgery Outcome in Brain Metastases
(Journal article; Peer reviewed, 2022)Background Following stereotactic radiosurgery (SRS), predicting treatment response is not possible at an early stage using structural imaging alone. Hence, the current study aims at investigating whether dynamic ... -
Dynamic Topography Development North of Iceland from Subaerial Exposure of the Igneous Logi Ridge, NE Atlantic
(Peer reviewed; Journal article, 2019)The Logi Ridge, located north of the West Jan Mayen Fracture Zone, is E-W oriented and 140-150 km long. The seafloor surrounding the Logi Ridge is ~0.65 km shallower than the conjugate seafloor east of the Mohn’s Ridge, ... -
Dynamical controls on the longevity of a non-linear vortex : The case of the Lofoten Basin Eddy
(Peer reviewed; Journal article, 2019-09-17)The Lofoten Basin is the largest oceanic reservoir of heat in the Nordic Seas, and the site of important heat fluxes to the atmosphere. An intense permanent anticyclone in the basin impacts the regional hydrography, ... -
Dynamical downscaling of ERA-40 in complex terrain using the WRF regional climate model
(Peer reviewed; Journal article, 2010)Results from a first-time employment of the WRF regional climate model to climatological simulations in Europe are presented. The ERA-40 reanalysis (resolution 1 ) has been downscaled to a horizontal resolution of 30 and ... -
Dynamical drivers of Greenland blocking in climate models
(Journal article; Peer reviewed, 2021)Blocking over Greenland is known to lead to strong surface impacts, such as ice sheet melting, and a change in its future frequency can have important consequences. However, as previous studies demonstrated, climate models ... -
Dynamical Grooming meets LHC data
(Journal article; Peer reviewed, 2021)In this work, we analyse the all-orders resummation structure of the momentum sharing fraction, zg, opening angle, θg, and relative transverse momentum, kt,g, of the splitting tagged by the Dynamical Grooming procedure in ... -
Dynamical grooming of QCD jets
(Journal article; Peer reviewed, 2020-02-06)We propose a new class of infrared-collinear and Sudakov safe observables with an associated jet grooming technique that removes dynamically soft and large angle branches. It is based on identifying the hardest branch in ... -
Dynamical modeling of pathogenic bacteria in surface drinking water
(Master thesis, 2020-10-08)Dynamisk modellering av økologiske systemer har vært et interessant verktøy for å forstå samspillet mellom arter i naturen. I denne oppgaven konstruerer vi et dynamisk system for interaksjon mellom patogene bakterier og ... -
Dynamical Perspectives on the Formation and Intensification of Polar Lows
(Doctoral thesis, 2014-11-25)This thesis consists of a collection of scientific publications addressing dynamical aspects of the formation and intensification of polar lows. Polar lows are small scale, intense, short-lived cyclones developing over ... -
A dynamical systems characterization of atmospheric jet regimes
(Journal article; Peer reviewed, 2021)Atmospheric jet streams are typically separated into primarily “eddy-driven” (or polar-front) jets and primarily “thermally driven” (or subtropical) jets. Some regions also display “merged” jets, resulting from the ... -
Dynamically combining climate models to "supermodel" the tropical Pacific
(Peer reviewed; Journal article, 2016-01)We construct an interactive ensemble of two different climate models to improve simulation of key aspects of tropical Pacific climate. Our so-called supermodel is based on two atmospheric general circulation models (AGCMs) ... -
Dynamically groomed jet radius in heavy-ion collisions
(Journal article; Peer reviewed, 2022)We explore the ability of a recently proposed jet substructure technique, dynamical grooming, to pin down the properties of the quark-gluon plasma formed in ultrarelativistic heavy-ion collisions. In particular, we compute, ... -
Dynamics and Predictability of the Extreme Extratropical Cyclone Nina
(Master thesis, 2016-06-01)An extreme extratropical cyclone struck western Norway at 12 UTC 10 January 2015 causing significant damage to property due to extreme winds. The European region has a history of being struck by extreme cyclones that cause ... -
Dynamics in the H2+ molecule, using a one dimensional model
(Master thesis, 2009-06-02)A 1D model of the hydrogen molecular ion in the Born-Oppenheimer (BO) approximation. The making and testing of the model is described, as well as some underlying theory. The model also calculates non-BO effects. -
The dynamics of 0-group herring Clupea harengus and sprat Sprattus sprattus populations along the Norwegian Skagerrak coast
(Journal article, 2022-07-18)Coastal areas are important habitats for early life stages of many fish species. These habitats are used as nursery grounds and can provide a significant contribution to the recruitment of a fish population. In 1919, ... -
The dynamics of a barotropic current impinging on an ice front
(Journal article; Peer reviewed, 2022)The vertical front of ice shelves represents a topographic barrier for barotropic currents that transport a considerable amount of heat toward the ice shelves. The blocking effect of the ice front on barotropic currents ... -
