   Spatial distribution of climatic variables and linear trends of surface freshwater flux (precipitation minus evaporation) has been analyzed based on NCEP reanalysis monthly dataset for 1948-2012. Low- frequency surface freshwater flux variability’ (more than 10 and 30 years) has been estimated in the present study.

Keywords: Precipitation, evaporation, variability, Atlantic ocean, reanalysis.
