An Empirical Eigenfunction Analysis of Sea Surface Temperatures in the Western North Atlantic
The Empirical Orthogonal Function (EOF) decomposition is used to analyze time records of AVHRR sea surface temperature observations of the Western North Atlantic from 32.9 ffi to 43.6 ffi N and from 62.7 ffi to 76.3 ffi W. A manually declouded dataset covering the spring of 1985 is analyzed. The maj...
