Modeling sea surface temperatures of the North Atlantic Ocean

An assessment of the trends and patterns of sea surface temperatures in the North Atlantic Ocean was carried out using statistical methods. The data were obtained from the climate research unit, comprising twenty-five 5 by 10° regions, covering latitudes 40 to 65°N and longitudes 10 to 60°W between...
