Recent Intensified Influence of the Winter North Pacific Sea Surface Temperature on the Mei-Yu Withdrawal Date
(Journal article; Peer reviewed, 2021)The mei-yu withdrawal date (MWD) is a crucial indicator of flood/drought conditions over East Asia. It is characterized by a strong interannual variability, but its underlying mechanism remains unknown. We investigated the ... -
Recent weakening in the winter ENSO teleconnection over the North Atlantic‑European region
(Journal article; Peer reviewed, 2021)New observational evidence for variability of the atmospheric response to wintertime El Niño-Southern Oscillation (ENSO) is found. Using different approaches and datasets, a weakening in the recent ENSO teleconnection over ... -
Recent wind driven high sea ice area export in the Fram Strait contributes to Arctic sea ice decline
(Peer reviewed; Journal article, 2011-10-14)Arctic sea ice area has been decreasing for the past two decades. Apart from melting, the southward drift through Fram Strait is the main ice loss mechanism. We present high resolution sea ice drift data across 79° N from ... -

Reconciling conflicting evidence for the cause of the observed early 21st century Eurasian cooling
(Journal article; Peer reviewed, 2023)It is now well established that the Arctic is warming at a faster rate than the global average. This warming, which has been accompanied by a dramatic decline in sea ice, has been linked to cooling over the Eurasian ... -
Reconciling Observation and Model Trends in North Atlantic Surface CO2
(Peer reviewed; Journal article, 2019)The North Atlantic Ocean is a region of intense uptake of atmospheric CO2. To assess how this CO2 sink has evolved over recent decades, various approaches have been used to estimate basin‐wide uptake from the irregularly ... -
Reconstructing the time history of the air-sea CO2 disequilibrium and its rate of change in the eastern subpolar North Atlantic, 1972–1989
(Peer reviewed; Journal article, 2006-02-18)This study determines the temporal changes of wintertime surface ocean partial pressure of CO2 (pCO2 SW) in the eastern subpolar North Atlantic (esNA) (50–64ºN; 32–10ºW) by using data of carbon-system parameters and ... -
Reconstructing winter climate anomalies in the Euro-Atlantic sector using circulation patterns
(Journal article; Peer reviewed, 2021)The efficacy of Euro-Atlantic circulation regimes for estimating wintertime climate anomalies (precipitation and surface temperature) over Europe is assessed. A comparison of seasonal climate reconstructions from two ... -
Reconstruction of Glacier Mass Balance and Sensitivity Tests to Climate Change: A case study of Ålfotbreen and Nigardsbreen
(Master thesis, 2011-11-30)A physically-based one dimensional CROCUS snow model was applied to simulate the surface mass balances of Ålfotbreen (1964-2009) and Nigardsbreen (1962-2009) in southern Norway. The required hourly meteorological input ... -
The red-sky enigma over Svalbard in December 2002
(Peer reviewed; Journal article, 2005)On 6 December 2002, during winter darkness, an extraordinary event occurred in the sky, as viewed from Longyearbyen (78° N, 15° E), Svalbard, Norway. At 07:30 UT the southeast sky was surprisingly lit up in a deep red ... -
A Regime View of ENSO Flavors Through Clustering in CMIP6 Models
(Journal article; Peer reviewed, 2023)El Niño-Southern Oscillation (ENSO) flavors in the tropical Pacific are studied from a regime perspective. Five recurring spatial patterns or regimes characterizing the diversity of ENSO are established using a clustering ... -
Regional atmospheric response to the Benguela Niñas
(Journal article; Peer reviewed, 2021)We investigate how the atmosphere is affected by the cold sea surface temperature (SST) anomalies of the Benguela Niñas using reanalysis data and a high-resolution atmospheric model. A composite analysis of reanalysis data ... -
Regional climate models' performance in representing precipitation and temperature over selected Mediterranean areas
(Peer reviewed; Journal article, 2013-12-12)This paper discusses the relative performance of several climate models in providing reliable forcing for hydrological modeling in six representative catchments in the Mediterranean region. We consider 14 Regional Climate ... -
Regional, seasonal, and predictable Arctic sea ice change
(Doctoral thesis, 2017-12-07)The loss of Arctic sea ice is one of the most prominent and best quantified indicators of ongoing global climate change. Satellite passive microwave observations since 1979 indicate significant negative sea ice extent ... -
Relating model bias and prediction skill in the equatorial Atlantic
(Journal article; Peer reviewed, 2021)We investigate the impact of large climatological biases in the tropical Atlantic on reanalysis and seasonal prediction performance using the Norwegian Climate Prediction Model (NorCPM) in a standard and an anomaly coupled ... -
Relation between the wind stress curl in the North Atlantic and the Atlantic inflow to the Nordic Seas
(Journal of Geophysical Research: Oceans, Journal article, 2008-06-27)In this study an isopycnic coordinate ocean model has been used to investigate the relationships between the North Atlantic wind stress curl (WSC) and the inflow of Atlantic water to the Nordic Seas. For the period 1995–2001, ... -
The relationship between the eddy-driven jet stream and northern European sea level variability
(Journal article; Peer reviewed, 2021)Wintertime sea level variability over the northern European continental shelf is largely wind-driven. Using daily gridded sea level anomaly from altimetry, we examine both the spatial and the temporal relationship between ... -
Relative importance of tropopause structure and diabatic heating for baroclinic instability
(Journal article; Peer reviewed, 2021)Misrepresentations of wind shear and stratification around the tropopause in numerical weather prediction models can lead to errors in potential vorticity gradients with repercussions for Rossby wave propagation and ... -
Remarkable link between projected uncertainties of Arctic sea-ice decline and winter Eurasian climate
(Journal article; Peer reviewed, 2018)We identify that the projected uncertainty of the pan-Arctic sea-ice concentration (SIC) is strongly coupled with the Eurasian circulation in the boreal winter (December–March; DJFM), based on a singular value decomposition ... -
Resampling of ENSO teleconnections: accounting for cold-season evolution reduces uncertainty in the North Atlantic
(Journal article; Peer reviewed, 2021)We re-examine the uncertainty of the El Niño–Southern Oscillation (ENSO) teleconnection to the North Atlantic following the investigation of Deser et al. (2017) (DES2017). Our analyses are performed on the November–December ...
