Conditional Weather Regimes and Moisture Pathways Associated With Summer Rainfall Over the Southeastern United States

International Journal of Climatology, EarlyView.
Persistent SEUS summer rainfall occurs within multiple recurrent circulation configurations that organize moisture convergence differently. Distinct combinations of NASH‐flank pressure anomalies, boundary moisture transport and vertical ascent can therefore support a similar regional wet state, highlighting multiple circulation–moisture pathways to ...

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

Physics of Atmospheres and Oceans

, 2007
The laws of classical mechanics and thermodynamics are used to explore how the properties of fluids on a rotating Earth manifest themselves in, and help shape, the global patterns of atmospheric winds, ocean currents, and the climate of the Earth ...

Climate‐modulated accumulation and erosion of sediments in the Rodderberg crater basin for the last 439 ka (East Eifel Volcanic Field, Germany)

Journal of Quaternary Science, EarlyView.
ABSTRACT Glacial/interglacial climate cycles since marine isotope stage (MIS) 12 influenced the discontinuous and 73 m‐long sediment record from the volcanic crater of Rodderberg in the East Eifel Volcanic Field, Germany. High‐resolution grain size and geochemical data have been valued by numerical dating techniques (radiocarbon and luminescence dating,

Forest Vapor Pressure Deficit Sensitivity: A Potential Indicator of Soil Carbon Stability Under Atmospheric Drying

Land Degradation &Development, EarlyView.
ABSTRACT This Short Report examines an underexplored link between atmospheric drying and soil organic carbon (SOC) stability. Rising atmospheric vapor pressure deficit (VPD) is becoming an increasingly important hydroclimatic stressor for terrestrial ecosystems.

Integrated Prediction and Analysis of Soil Erosion and Soil Organic Carbon Loss in the Dayekou Watershed, Qilian Mountains

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion poses a critical threat to ecological security in mountain watersheds worldwide. Predicting its dynamics and associated soil organic carbon (SOC) loss remains an ongoing challenge during the 21st century due to complex interactions among climate, land use, and topography.

Ocean-atmosphere interaction : improvement of wind stress for coastal physical modelling

Interaction Océan-Atmosphère : amélioration de la tension de vent en modélisation physique côtière Les surcotes de tempête sont souvent sous-estimées dans les modèles hydrodynamiques, ainsi que les grandes vagues dans les modèles de vagues. Les causes possibles sont une sous-estimation des vents dans les modèles atmosphériques et/ou une

Introducing a ramped pyrolysis/oxidation‐14CO2 analysis system operated with mobile molecular sieve traps

Limnology and Oceanography: Methods, EarlyView.
Abstract A novel instrument for the thermal degradation of sedimentary organic matter was set up at the Alfred Wegener Institute (AWI) in Bremerhaven, Germany, with the aim of enabling Ramped Pyrolysis/Oxidation‐14C analysis as direct CO2 gas measurement.
