I've been searching and reading few literature about EOF and it's application over meteorology data. It's rather confusing and did not answer my vital question ; Why do we need to perform EOF over the data.
Finally come across this page : http://meteora.ucsd.edu/~jnorris/sio209.sp01/EOF_background.pdf
..clears my inquiries a little, although then another question came, Should or not I use this method to my data?
that's all about research. A question answered just to get us to another question.
