Identifying airborne snow metamorphism with stable water isotopes
(Journal article; Peer reviewed, 2024)Wind-blown snow is a frequent phenomenon in high-elevation and polar regions which impacts the surface energy and mass balance of these areas. Loose surface snow gets eroded and transported by wind, which influences the ... -
CMIP6 near-term and long-term projections of Eurasian winter cooling trend and cold extremes
(Journal article; Peer reviewed, 2024)It is well-known that climate warming increases air temperature and reduces cold extremes in the long-term. But internal variability strongly modulates the variability of temperature at mid- and- high latitudes, for example, ... -
Variations in Rainfall Structure of Western North Pacific Landfalling Tropical Cyclones in the Warming Climates
(Journal article; Peer reviewed, 2024)Observations and climate projections suggest a larger increase in tropical cyclone (TC)-induced rainfall than that can be explained by the Clausius-Clapeyron relationship of 7% increase in vapor content for each 1°C degree ... -
Impact of swell waves on atmospheric surface turbulence: wave–turbulence decomposition methods
(Journal article; Peer reviewed, 2024)To study turbulence properties, specifically vertical momentum fluxes under swell wave conditions, I investigate the impact of waves on the power spectrum and spectral coherence of turbulent wind across various spatial and ... -
Drivers and impact of the 2021 extreme warm event in the tropical Angolan upwelling system
(Journal article; Peer reviewed, 2024)Benguela Niños are extreme warm events that typically occur during the main downwelling season (austral fall) in the tropical Angolan upwelling system when the biological productivity is low. However, the extreme warm event ... -
Recent Thickening of the Barents Sea Ice Cover
(Journal article; Peer reviewed, 2024)The Arctic sea ice cover has decreased rapidly over the last few decades both in extent and thickness. Here we present multi-year (2013–2022) observations of sea ice thickness in the northwestern Barents Sea based on Upward ... -
Observations of the Antarctic Slope Current in the Southeastern Weddell Sea: A Bottom-Enhanced Current and Its Seasonal Variability
(Journal article; Peer reviewed, 2024)The Antarctic Slope Front and the associated Antarctic Slope Current dynamically regulate the exchanges of heat across the continental shelf break around Antarctica. Where the front is weak, relatively warm deep waters ... -
The Polar Front in the northwestern Barents Sea: structure, variability and mixing
(Journal article; Peer reviewed, 2024)In the northwestern Barents Sea the warm and salty Atlantic Water meets the cold and fresh Polar Water, forming a distinct thermohaline front, the Barents Sea Polar Front. Here we present the structure of the front, its ... -
On the importance of the humidity flux for the surface mass balance in the accumulation zone of the Greenland Ice Sheet
(Journal article; Peer reviewed, 2024)It is highly uncertain how the humidity flux between the snow surface and the atmosphere contributes to the surface mass balance (SMB) of the interior Greenland Ice Sheet (GrIS). Due to sparse observations, evaluations of ... -
Causal Links Between Sea-Ice Variability in the Barents-Kara Seas and Oceanic and Atmospheric Drivers
(Journal article; Peer reviewed, 2024)The sea-ice cover in the Barents and Kara Seas (BKS) displays pronounced interannual variability. Both atmospheric and oceanic drivers have been found to influence sea-ice variability, but their relative strength and ... -
Sources of low-frequency variability in observed Antarctic sea ice
(Journal article; Peer reviewed, 2024)Antarctic sea ice has exhibited significant variability over the satellite record, including a period of prolonged and gradual expansion, as well as a period of sudden decline. A number of mechanisms have been proposed to ... -
An analysis of air-sea gas exchange for the entire MOSAiC Arctic drift
(Journal article; Peer reviewed, 2024)Sea ice cover influences the generation of surface ocean turbulence in ways that sometimes enhance, but mostly inhibit air-water gas exchange. Inhibition happens as ice cover reduces wind fetch, enhancement occurs when ... -
Enriched local convenience foods with two different small pelagic fish species increases the nutritional value without compromising taste
(Journal article; Peer reviewed, 2024)Cereals and their derived products are important dietary sources for humans but are mostly deficient in protein and several micronutrients. To increase the nutrient content of rice and wheat flour-based recipes, nutrient-dense ... -
Enhancing Wind Resource Predictability for Power Generation Based on NORA3 Hindcast Data
(Master thesis, 2024-12-19)The rising global energy demand, coupled with the urgent need to fully address climate change, has driven a critical shift from fossil fuels—still accounting for 80% of energy consumption in 2022—to renewable energy sources. ... -
Ocean warming drives immediate mass loss from calving glaciers in the high Arctic
(Journal article; Peer reviewed, 2024)Glaciers in the Arctic have lost considerable mass during the last two decades. About a third of the glaciers by area drains into the ocean, yet the mechanisms and drivers governing mass loss at glacier calving fronts are ... -
Power in urban logistics: A comparative analysis of networks and policymaking in logistics sustainability governance
(Journal article; Peer reviewed, 2024)This article unpacks the power relations in urban logistics to understand why cities follow different policy pathways to sustainability. Drawing on the literature on power in sustainability transitions, we investigate key ... -
Dakar Niño under global warming investigated by a high-resolution regionally coupled model
(Journal article; Peer reviewed, 2024)In this study, we investigated interannual variability in sea surface temperature (SST) along the northwestern African coast, focusing on strong Dakar Niño and Niña events and their potential alterations under the RCP8.5 ... -
Observed Pathways and Interannual Variability of the Warm Inflow Onto the Continental Shelf in the Southern Weddell Sea
(Journal article; Peer reviewed, 2024)Model projections suggest that the continental shelf in the southern Weddell Sea may experience a shift from today's near-freezing temperature to a much warmer state, where warm water floods the shelf and basal melt rates ... -
Extreme wind events responsible for an outsized role in shelf-basin exchange around the southern tip of Greenland
(Journal article; Peer reviewed, 2024)The coastal circulation around Southern Greenland transports fresh, buoyant water masses from the Arctic and Greenland Ice Sheet near regions of convection, sinking, and deep-water formation in the Irminger and Labrador ... -
Adaptive Covariance Hybridization for the Assimilation of SST Observations Within a Coupled Earth System Reanalysis
(Journal article; Peer reviewed, 2024)Ensemble data assimilation methods, such as the Ensemble Kalman Filter (EnKF), are well suited for climate reanalysis because they feature flow-dependent covariance. However, because Earth System Models are heavy ...
