If nothing else changes you should find some correlations. Departure from 
the requirements that certain tree species have (too wet or too dry) should 
mean less than average tree ring growth. You might even find correlations in 
an optimal range where tree ring growth changes with the precipitation.

But please be aware that temperature also is a major influence factor. Did 
you read the article in Nature last summer on temperature variations showing 
off in tree ring growth? Find it, the last December number of Nature has a 
title index.

Might be helpful
