Sea surface temperature variability: Patterns and mechanisms
TL;DR: Patterns of sea surface temperature variability on interannual and longer timescales result from a combination of atmospheric and oceanic processes, notably the Atlantic Multidecadal Oscillation.
Journal ArticleDOI
Impacts of climate change on fisheries
TL;DR: In this paper, the impacts of anthropogenic climate change on marine ecosystems are evaluated in the context of the "normal" climate cycles and variability which have caused fluctuations in fisheries throughout human history.
Journal ArticleDOI
On the Increased Frequency of Mediterranean Drought
TL;DR: In this paper, a change in wintertime Mediterranean precipitation toward drier conditions has likely occurred over 1902-2010 whose magnitude cannot be reconciled with internal variability alone, and anthropogenic greenhouse gas and aerosol forcing are key attributable factors for increased drying, though the external signal explains only half of the drying magnitude.

Variability of the North Atlantic Oscillation over the past 5,200 years
TL;DR: In this article, a 5,200-year-long lake sediment record was used to reconstruct the circulation patterns associated with the North Atlantic Oscillation (NAO) in the Arctic and northern Europe.
Journal ArticleDOI
Wave climate variability in the North-East Atlantic Ocean over the last six decades
TL;DR: In this article, a 57-year hindcast (1953-2009) obtained with a spectral wave model forced with reanalysis wind fields was used to investigate the variability in the North-East Atlantic Ocean (25°W-0°W and 30°N-60° N).

Jenne,Dennis Joseph +21 more
TL;DR: The NCEP/NCAR 40-yr reanalysis uses a frozen state-of-the-art global data assimilation system and a database as complete as possible, except that the horizontal resolution is T62 (about 210 km) as discussed by the authors.
Journal ArticleDOI
Deterministic nonperiodic flow
TL;DR: In this paper, it was shown that nonperiodic solutions are ordinarily unstable with respect to small modifications, so that slightly differing initial states can evolve into considerably different states, and systems with bounded solutions are shown to possess bounded numerical solutions.

Decadal Trends in the North Atlantic Oscillation: Regional Temperatures and Precipitation
TL;DR: An evaluation of the atmospheric moisture budget reveals coherent large-scale changes since 1980 that are linked to recent dry conditions over southern Europe and the Mediterranean, whereas northern Europe and parts of Scandinavia have generally experienced wetter than normal conditions.
Journal ArticleDOI
The Arctic oscillation signature in the wintertime geopotential height and temperature fields
TL;DR: The Arctic Oscillation (AO) as mentioned in this paper is the signature of modulations in the strength of the polar vortex aloft, and it resembles the NAO in many respects; but its primary center of action covers more of the Arctic, giving it a more zonally symmetric appearance.

Teleconnections in the Geopotential Height Field during the Northern Hemisphere Winter
John M. Wallace,David S. Gutzler +1 more
TL;DR: In this paper, a review of existing literature on the subject reveals the existence of at least four such patterns: the North Atlantic and North Pacific Oscillations identified by Walker and Bliss (1932), a zonally symmetric seesaw between sea level pressures in polar and temperature latitudes, first noted by Lorenz (1951), and what we will refer to as the Pacific/North American pattern, which has been known to operational long-range forecasters in this country since the 1950's.
