Response of the eastern North Atlantic subpolar gyre to the North Atlantic Oscillation [PDF]

Geophysical Research Letters, 2009
The salinity changes in the subpolar gyre (SPG) in response to the North Atlantic Oscillation (NAO) are studied in idealized numerical experiments. In the eastern SPG, anomalies of similar amplitude as those observed during the 1995–1996 shift of the NAO are mainly driven by the local response to the wind stress, through the set‐up of an anticyclonic ...

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Dicrananthera hedyotidea C. Presl. (Melastomataceae) in Maranhão state, Brazil: first record and ecological niche model of the species

Nordic Journal of Botany, EarlyView.
Dicrananthera C. Presl. is a monospecific genus of the tribe Marcetieae, comprising perennial herbs typically occurring in areas adjacent to wetlands. The species exhibits a disjunct distribution, with confirmed records in both the Amazon and Atlantic Forest domains.

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

Oikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

Is Tropical Atlantic Variability driven by the North Atlantic Oscillation? [PDF]

Geophysical Research Letters, 2002
The role of the North Atlantic Oscillation (NAO) on the genesis of the Tropical Atlantic Variability (TAV) is studied in a coupled ocean‐atmosphere general circulation model using two modeling approaches of partial coupling and partial blocking. It is found that the NAO is not a necessary precondition for the genesis of the TAV although it can enhance ...

Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.

Synergistic effects of the winter North Atlantic Oscillation (NAO) and El Niño–Southern Oscillation (ENSO) on dust activities in North China during the following spring [PDF]

Atmospheric Chemistry and Physics
Dust significantly influences global weather and climate by impacting the Earth's radiative balance. Based on reanalysis datasets, this study explores how the North Atlantic Oscillation (NAO) and El Niño–Southern Oscillation (ENSO) during winter impact ...

How consistently do ensemble prediction systems represent the growth of atmospheric uncertainty?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Spread‐based diagnostics calculated for 12 ensemble prediction systems are compared to understand the consistency with which they represent atmospheric uncertainty growth. Good correlation between all these systems is found in the extratropics for a lead time range from 48 hr to between 96 hr and 192 hr.

Increased persistence of warm and wet winter weather in recent decades in north-western Europe

Communications Earth & Environment
Changes in weather persistence have important implications for flood risk and regional climate resilience. In recent decades, the winter North Atlantic Oscillation index has shown a sustained shift toward more strongly positive values, exceeding the ...
