Article Abstract:
The mechanics of decadal climate variability in the tropical Atlantic Ocean was analyzed in an ocean-atmosphere model. The hybrid coupled general ocean-atmosphere feedback model can be utilized to predict the atmosphere's response to variations in sea surface temperature. Furthermore, the empirical atmospheric feedback model can provide data on the dipole-like variability of atmospheric-ocean interactions in the tropical Atlantic which is vital for long-term weather forecasting.

Article Abstract:
Changes in water temperature and salinity in the northeastern North Atlantic since the 1960s show that global warming is not an unvarying process. J.F. Read and W.J. Gould analysed data from fisheries and other sources and found that moderately deep sea water was both colder and less salty than before, which may indicate at least a temporary reversal of atmospheric warming. Further research is necessary to clarify how North Atlantic circulation relates to climatic changes.

Article Abstract:
Previous studies of the Nordic seas have found no significant or long-term variation in the outflow of water to the Atlantic Ocean. New research uses flows from hydrographic data to reveal that the outflow has approximately doubled before returning to accepted values over the past 40 years. It is suggested that the variability is caused by variations in polar air temperature, itself connected to Arctic warming.
