Arctic sea ice altimetry - advances and current uncertainties
(Doctoral thesis, 2014-06-11)One of the most prominent features of global climate change is the reduction in Arctic sea ice thickness. The main tool to derive sea ice thickness on an Arctic wide scale is altimetry from satellites, yet current estimates ... -
Arctic sea ice and climate change - will the sea ice disappear in this century?
(Peer reviewed; Journal article, 2000) -
Arctic sea ice and Eurasian climate: A review
(Peer reviewed; Journal article, 2014-11-28)The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades, including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the ... -
The Arctic sea ice extent change connected to Pacific decadal variability
(Journal article; Peer reviewed, 2020)After an unprecedented retreat, the total Arctic sea ice cover for the post-2007 period is characterized by low extent and a remarkable increase in annual cycle amplitude. We have identified the leading role of spring ... -
Arctic Sea level Budget Assessment During the GRACE/Argo Time Period
(Journal article; Peer reviewed, 2020)Sea level change is an important indicator of climate change. Our study focuses on the sea level budget assessment of the Arctic Ocean using: (1) the newly reprocessed satellite altimeter data with major changes in the ... -
The Arctic Summer Cloud Ocean Study (ASCOS): Overview and experimental design
(Peer reviewed; Journal article, 2014-03-19)The climate in the Arctic is changing faster than anywhere else on earth. Poorly understood feedback processes relating to Arctic clouds and aerosol–cloud interactions contribute to a poor understanding of the present ... -
Arctic tidal current atlas
(Journal article; Peer reviewed, 2020)Tidal and wind-driven near-inertial currents play a vital role in the changing Arctic climate and the marine ecosystems. We compiled 429 available moored current observations taken over the last two decades throughout the ... -
Arctic Warming and Eurasian Cooling: Weakening and Reemergence
(Journal article; Peer reviewed, 2023)The observed Eurasian winter surface cooling from the 1990s to the early 2010s, which is contrary to global warming, has been extensively studied. Previous studies revealed that the surface cooling trend has significantly ... -
Arctic Wintertime Sea Ice Breakup Events - Detection and Evolution
(Master thesis, 2024-06-03)Openings in the Arctic sea ice give rise to strong localized heat fluxes from the ocean to the atmosphere, causing ocean mixing and potentially leading to new sea ice growth. Despite the increased attention on sea ice ... -
Arctic-Atlantic Climate Variability and Predictability in Observations and in a Dynamical Prediction System
(Doctoral thesis, 2023-11-03)Hovedfokuset i denne doktorgradsoppgaven er å forstå dekadisk klimaprediktabilitet (forutsigbarhet i klimaet) for å forbedre klimamodeller og klimavarsel. Klimavarseling viser lovende resultat, men det er fremdeles ... -
Arctic/Atlantic exchanges via the Subpolar Gyre
(Peer reviewed; Journal article, 2012)In the present study we investigate the decadal variability in the strength and shape of the Subpolar Gyre (SPG) in a 600-year pre-industrial simulation using the Bergen Climate Model. The atmospheric influence on the SPG ... -
Aspects on interactions between mid- to high latitude atmospheric circulation and some surface processes
(Doctoral thesis, 2006-06-08)The Arctic is a hot topic in Climate Research. A large number of signs of a warming Arctic Climate have been identified the latest years. This is of major concern in light of the increasing atmospheric content of greenhouse ... -
Assessing the influence of sea surface temperature and arctic sea ice cover on the uncertainty in the boreal winter future climate projections
(Journal article; Peer reviewed, 2022)We investigate the uncertainty (i.e., inter-model spread) in future projections of the boreal winter climate, based on the forced response of ten models from the CMIP5 following the RCP8.5 scenario. The uncertainty in the ... -
Assessing the Norwegian Offshore Wind Resources: Climatology, Power Variability and Wind Farm Siting
(Doctoral thesis, 2022-09-09)De norske havvindressursene er fantastiske. Likevel er det ingen operative vindparker i de norske havvområdene. Tatt i betraktning både utslippsmål og forventet økning i elektrisitetsforbruk har regjerningen nå begynt å ... -
Assessing the Sampling Quality of a Low-Tech Low-Budget Volume-Based Rainfall Sampler for Stable Isotope Analysis
(Peer reviewed; Journal article, 2019-09-27)To better understand the small-scale variability of rainfall and its isotopic composition it is advantageous to utilize rain samplers which are at the same time low-cost, low-tech, robust, and precise with respect to the ... -
Assessment of Atmospheric Reanalyses With Independent Observations in the Weddell Sea, the Antarctic
(Peer reviewed; Journal article, 2019)Surface layer and upper‐air in situ observations from two research vessel cruises and an ice station in the Weddell Sea from 1992 and 1996 are used to validate four current atmospheric reanalysis products: ERA‐Interim, ... -
An Assessment of CO2 Uptake in the Arctic Ocean From 1985 to 2018
(Journal article; Peer reviewed, 2023)As a contribution to the Regional Carbon Cycle Assessment and Processes phase 2 (RECCAP2) project, we present synthesized estimates of Arctic Ocean sea-air CO2 fluxes and their uncertainties from surface ocean pCO2-observation ... -
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 ... -
