Is there a reliable way to identify regions with negatively-correlated winds?

My suggestion would be to do a Principal Component Analysis (PCA) or Empirical Orthogonal Functions (EOF) analysis on the wind data. The result of the analysis would be a set of modes of variability. ...

How to obtain the correlation between monthly streamflows based on physical concepts?

One suggestion on generating the monthly flows is to use a seasonal ARMA model directly (e.g. see course notes), since you are looking at ARMA model for stochastic generation anyway. That would allow ...
