An assessment of future extreme precipitation in western Norway using a linear model
(Peer reviewed; Journal article, 2010-11-26)A Linear Model (Smith and Barstad, 2004) was used to dynamically downscale Orographic Precipitation over western Norway from twelve General Circulation Model simulations. The GCM simulations come from the A1B emissions ... -
Assessment of wind conditions at a fjord inlet by complementary use of sonic anemometers and lidars
(Peer reviewed; Journal article, 2015-12-02)Wind velocity measurement devices based on the remote optical sensing, lidars, are extensively applied in wind energy research and wind farm operation. The present paper demonstrates the relevance and potential of lidar ... -
The Atlantic inflow across the Greenland-Scotland ridge in global climate models (CMIP5)
(Peer reviewed; Journal article, 2019-05-21)Oceanic heat transport from the North Atlantic to the Arctic through the Nordic Seas is a key component of the climate system that has to be modelled accurately in order to predict, for example, future Arctic sea ice changes ... -
Atlantic Meridional Overturning Circulation and δ13C Variability During the Last Interglacial
(Peer reviewed; Journal article, 2020)The Atlantic Meridional Overturning Circulation (AMOC) is thought to be relatively vigorous and stable during Interglacial periods on multimillennial (equilibrium) timescales. However, recent proxy (δ13C benthic) reconstructions ... -
Atlantic Multidecadal Oscillation modulates the impacts of Arctic sea ice decline
(Peer reviewed; Journal article, 2018-03)The Arctic sea ice cover has been rapidly declining in the last two decades, concurrent with a shift in the Atlantic Multidecadal Oscillation (AMO) to its warm phase around 1996/1997. Here we use both observations and model ... -
Atlantic Multidecadal Variability (AMV) in the Norwegian Earth System model
(Master thesis, 2020-06-26)The causes of low-frequency sea surface temperature (SST) variations in the Atlantic, known as Atlantic Multidecadal Variability (AMV), are debated. AMV has climatic impacts on for instance hurricane activity and Sahel ... -
The Atlantic Multidecadal Variability phase-dependence of teleconnection between the North Atlantic Oscillation in February and the Tibetan Plateau in March
(Journal article; Peer reviewed, 2021)The Tibetan Plateau (TP), referred to as the “Asian water tower,” contains one of the largest land ice masses on Earth. The local glacier shrinkage and frozen-water storage are strongly affected by variations in surface ... -
Atlantic thermohaline changes and its implications on the carbon cycle during the Last Interglacial
(Doctoral thesis, 2020-06-16)Large and abrupt changes in the Earth’s climate have been recorded in marine records and Greenland ice cores and mostly characterize the last glacial period. These sudden transitions of climate, occurring within a few ... -
The Atlantic Water flow along the Vøring Plateau: Detecting frontal structures in oceanic station time series
(Deep-Sea Research 54(3), 2007-01-13)The topographic steering of the baroclinic western branch of the Norwegian Atlantic Current (NwAC) determines the extent of Atlantic Water and location of the Arctic Front in the Nordic Seas. In this paper the geographical ... -
Atlantic Water in the Arctic Ocean - Mechanisms and Impacts
(Doctoral thesis, 2021-08-19)The Arctic Ocean plays a fundamental role in regulating Earth’s climate, and a changing Arctic will affect climate, weather, and life everywhere on the planet. Understanding the fundamental dynamics and mechanisms driving ... -
Atlantic Water Inflow Through the Yermak Pass Branch: Evolution Since 2007
(Journal article; Peer reviewed, 2022)Thirty-four months (2017–2020) of mooring data were recently obtained at 80.6°N, 7.26°E in the main branch of Atlantic Water inflow to the Arctic, the Yermak Pass Branch. The Yermak Pass Branch was sampled at that same ... -
Atlantic Water Pathways Along the North-Western Svalbard Shelf Mapped Using Vessel-Mounted Current Profilers
(Peer reviewed; Journal article, 2019-03)A large amount of warm Atlantic water (AW) enters the Arctic as a boundary current through Fram Strait (West Spitsbergen Current [WSC]) and is the major oceanic heat source to the Arctic Ocean. Along the north‐western ... -
Atlantic water transformation along its poleward pathway across the Nordic Seas
(Peer reviewed; Journal article, 2018-08-23)The warm and salty Atlantic Water is substantially modified along its poleward transit across the Nordic Seas, where it reaches deeper isopycnals. In particular, the Lofoten Basin, exposed to intense air‐sea interactions, ... -
An Atlantic-driven rapid circulation change in the North Pacific Ocean during the late 1990s
(Peer reviewed; Journal article, 2019-10-08)Interbasin interactions have been increasingly emphasized in recent years due to their roles in shaping climate trends and the global warming hiatus in the northern hemisphere. The profound influence from the North Atlantic ... -
Atlantic-Origin Overflow Water in the East Greenland Current
(Peer reviewed; Journal article, 2019)Dense water masses transported southward along the east coast of Greenland in the East Greenland Current (EGC) form the largest contribution to the Denmark Strait Overflow. When exiting Denmark Strait these dense water ... -
Atmospheric boundary layers in storms: advanced theory and modelling applications
(Peer reviewed; Journal article, 2005-03-29)Turbulent planetary boundary layers (PBLs) control the exchange processes between the atmosphere and the ocean/land. The key problems of PBL physics are to determine the PBL height, the momentum, energy and matter fluxes ... -
Atmospheric Circulation Response to Short-Term Arctic Warming in an Idealized Model
(Journal article; Peer reviewed, 2020)Recent Arctic sea ice loss in fall has been posited to drive midlatitude circulation changes into winter and even spring. Past work has shown that sea ice loss can indeed trigger a weakening of the stratospheric polar ... -

Atmospheric response to removal of Southern Hemisphere sea ice - a model study
(Master thesis, 2010-06-01)The atmospheric response to the removal of Southern Hemisphere sea ice is studied using the ICTP AGCM (SPEEDY) model with an uncoupled ocean. The results show large increases in surface heat flux from the ocean to the ... -
Atmospheric response to zonally averaged sea surface temperatures in the North Atlantic - a model study
(Master thesis, 2008-05-29)A less dynamically active ocean will most likely lead to a more zonal sea surface temperature (SST) distribution. In order to identify if, and how such an effect affects the atmospheric variability, idealized experiments ...
