Role of wind stress in driving SST biases in the tropical Atlantic
(Journal article; Peer reviewed, 2019-03-13)Coupled climate models used for long-term future climate projections and seasonal or decadal predictions share a systematic and persistent warm sea surface temperature (SST) bias in the tropical Atlantic. This study attempts ... -
Seasonal predictions initialised by assimilating sea surface temperature observations with the EnKF
(Peer reviewed; Journal article, 2019-07-23)This study demonstrates that assimilating SST with an advanced data assimilation method yields prediction skill level with the best state-of-the-art systems. We employ the Norwegian Climate Prediction Model (NorCPM)—a ... -
Sensitivity of simulated wintertime Arctic atmosphere to vertical resolution in the ARPEGE/IFS model
(Journal article, 2008)The current state of the art general circulation models, including several of those used by the IPCC, show considerable disagreement in simulating present day high latitude climate. This is of major concern and reduces the ... -
Simulated variability of the Atlantic meridional overturning circulation
(Journal article, 2004-04-17)To examine the multi-annual to decadal scale variability of the Atlantic Meridional Overturning Circulation (AMOC), a four-member ensemble with a daily reanalysis forced, medium-resolution global version of the isopycnic ... -
Uncertainty in twenty-first century projections of the Atlantic Meridional Overturning Circulation in CMIP3 and CMIP5 models
(Peer reviewed; Journal article, 2016-05-26)Uncertainty in the strength of the Atlantic Meridional Overturning Circulation (AMOC) is analyzed in the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5) projections for the twenty-first century; ... -
Variability along the Atlantic water pathway in the forced Norwegian Earth System Model
(Peer reviewed; Journal article, 2018-03-27)The growing attention on mechanisms that can provide predictability on interannual-to-decadal time scales, makes it necessary to identify how well climate models represent such mechanisms. In this study we use a high (0.25° ... -
Winter Arctic Amplification at the synoptic timescale, 1979–2018, its regional variation and response to tropical and extratropical variability
(Journal article; Peer reviewed, 2021)We investigate winter Arctic Amplification (AA) on synoptic timescales and at regional scales using a daily version of the Arctic Amplification Index (AAI) and examine causes on a synoptic scale. The persistence, frequency ...
