Empirical orthogonal function (EOF) analysis was applied to the combined set of summer temperature precipitation over the Great Lake region, and water supplies to the Great Lakes. The purpose of this analysis to determine the association between these three variables. The results show that the predominant association between temperature and precipitation is a negative one, although a positive association is important central and eastern portions of the region. The water supplies to the lakes are more closely associated (positively) with precipitation than with temperature. Comparison between the results of the EOF analysis of the combined set of temperature, precipitation, water supplies (TPS) and the results of separate EOF analyses of temperature (T), precipitation ( P ), and supplies (S) shows that although the first loading patterns of T, P and S do appear in the combined loading of TPS, they do not appear together in the same pattern of TPS. This result provides further insight into the of the association between these variables.
