Asymmetries in Circulation Anomalies Related to the Phases of the North Atlantic Oscillation on Synoptic Time Scales
(Peer reviewed; Journal article, 2022)The North Atlantic Oscillation (NAO) index is often characterized by independent positive and negative NAO events with a characteristic spatial pattern and a typical lifetime of around 1 week. These events are separated ... -
Deepening of Southern Ocean Gateway Leads to Abrupt Onset of a Deep-Reaching Meridional Overturning Circulation
(Journal article; Peer reviewed, 2023)Around 50–34 million years ago, the Southern Hemisphere witnessed a major reorganization of continents. This led to the opening and deepening of two Southern Ocean gateways (OGs)—the Tasmanian Gateway between Australia and ... -
Dissolution Dominates Silica Cycling in a Shelf Sea Autumn Bloom
(Peer reviewed; Journal article, 2019)Small marine microalgae called diatoms are responsible for significant levels of primary production in support of marine ecosystems. Diatom cells are formed from silica dissolved in seawater; however, diatom cells may also ... -
Drivers of Subseasonal Forecast Errors of the East African Short Rains
(Peer reviewed; Journal article, 2021)The ‘short rains’ in East Africa from October to December have significant year-to-year variability. Their abundance or deficiency is often associated with floods or droughts for which early warning is crucial, though even ... -
Elevation changes of the Fennoscandian Ice Sheet interior during the last deglaciation
(Journal article; Peer reviewed, 2020)The dynamics of ice sheet interiors during the last deglaciation are poorly constrained, hindering evaluation of ice sheet models. We provide direct evidence of Fennoscandian Ice Sheet (FIS) interior behaviour during ... -
Future sea level change under CMIP5 and CMIP6 scenarios from the Greenland and Antarctic ice sheets
(Peer reviewed; Journal article, 2021)Projections of the sea level contribution from the Greenland and Antarctic ice sheets (GrIS and AIS) rely on atmospheric and oceanic drivers obtained from climate models. The Earth System Models participating in the Coupled ... -
Inequal responses of drylands to radiative forcing geoengineering methods
(Peer reviewed; Journal article, 2019)Climate geoengineering has the potential to reduce global warming. However, the nonlinear responses of Earth's large‐scale circulation to climate geoengineering can exacerbate regional climate change, with potential ... -
Lumikot: Fast auroral transients during the growth phase of substorms
(Peer reviewed; Journal article, 2019)The development of a magnetospheric substorm may be classified into three phases: growth, expansion, and recovery. The growth phase is important as it includes processes that lead to the expansion. In a recent growth-phase ... -
On the Potentials and Limitations of Attributing a Small-Scale Climate Event
(Peer reviewed; Journal article, 2022)Intense convective storms can be hazardous when occurring over large populated cities. In a changing climate, decision makers and the general public increasingly need to be able to better understand if and to what extent ... -
Revisiting the Mechanisms of ENSO Response to Tropical Volcanic Eruptions
(Journal article; Peer reviewed, 2023)Stratospheric volcanic aerosol can have major impacts on global climate. Despite a consensus among studies on an El Niño-like response in the first or second post-eruption year, the mechanisms that trigger a change in the ... -
Sensitivity of Rainfall Extremes to Unprecedented Indian Ocean Dipole Events
(Peer reviewed; Journal article, 2024)Strong positive Indian Ocean Dipole (pIOD) events like those in 1997 and 2019 caused significant flooding in East Africa. While future projections indicate an increase in pIOD events, limited historical data hinders a ... -
Stronger Oceanic CO2 Sink in Eddy-Resolving Simulations of Global Warming
(Peer reviewed; Journal article, 2024)Accurately representing the ocean carbon cycle in Earth System Models (ESMs) is essential to understanding the oceanic CO2 sink evolution under CO2 emissions and global warming. A key uncertainty arises from the ESM's ... -
Thirty Years of GOSHIP and WOCE Data: Atlantic Overturning of Mass, Heat, and Freshwater Transport
(Peer reviewed; Journal article, 2022)The Atlantic Meridional Overturning Circulation (AMOC) plays a vital role in global climate, redistributing heat, and freshwater. It is predicted to decline due to anthropogenic climate change, with major implications for ... -
Underestimated Land Heat Uptake Alters the Global Energy Distribution in CMIP6 Climate Models
(Peer reviewed; Journal article, 2024)Current global warming results in an uptake of heat by the Earth system, which is distributed among the different components of the climate system. However, current-generation climate models deliver heat inventory and ... -
Wintertime fCO2 variability in the subpolar North Atlantic since 2004
(Peer reviewed; Journal article, 2019)Winter data of surface ocean temperature (SST), salinity (SSS) and CO2 fugacity (fCO2) collected on the VOS M/V Nuka Arctica in the subpolar North Atlantic between 2004 and 2017 are used to establish trends, drivers, and ...
