Abstract: Strong multidecadal variability is detected in a 300-yr integration of the NCAR Climate System Model in the South Atlantic region, through the application of two signal recognition techniques: the multitaper method and ...

Abstract: The variability of the meridional overturning circulation (MOC) in the upper tropical Atlantic basin is investigated using a reduced-gravity model in a simplified domain. Four sets of idealized numerical experiments are ...

Abstract: his study analyzes important aspects of the tropical Atlantic Ocean from simulations of the fourth version of the Community Climate System Model (CCSM4): the mean sea surface temperature (SST) and wind stress, the Atlantic ...

Abstract: Observed rainfall, outgoing longwave radiation (OLR), divergence, and precipitation from the reanalysis project of the National Centers for Environmental Prediction and the National Center for Atmospheric Research are ...

Abstract: Intercomparison of the seasonal cycle for the fluxes of sensible and latent heat for four observation-based products [DaSilva, NCEP, Esbensen?Kushnir (EK), and the Southampton Oceanography Centre (SOC)] and the results for ...

Abstract: Onset and end of the rainy season in the Amazon Basin are examined for the period 1979?96. The onset and end dates are determined by averaging daily rainfall data from many stations, and then constructing 5-day averages ...

Abstract: he new Community Climate System Model, version 4 (CCSM4), provides a powerful tool to understand and predict the earth?s climate system. Several aspects of the Southern Ocean in the CCSM4 are explored, including the surface ...

Abstract: Extratropical atmosphere?ocean variability over the Northern Hemisphere of the Community Climate System Model version 3 (CCSM3) is examined and compared to observations. Results are presented for an extended control ...
