Empirical eigenvector analysis of vector observations


  • Donald M. Hardy


A method of deriving an empirical eigenvector or principal components representation of wind velocity measurements is given. The mathematical basis for generalizing the empirical eigenvector method to the treatment of vector data fields is stated briefly. The method presented can be employed in the analysis of regional wind velocity patterns. Applications of the analysis technique to other geophysical vector fields are also possible.
