WebAlthough REOF could compensate for the drawbacks of EOF or PCA, this method cannot deal with the spatial heterogeneity or non-stationarity (Hannachi et al., 2007). Most importantly, all these methods only use the correlation of the space-time field of a specific variable and tend to neglect its spatial information. http://meteothink.org/examples/meteoinfolab/meteo_analysis/eof.html
