Precipitation anomalies; Meteorology--Minnesota


Eigenvalues and eigenvectors computed on 30-year normals indicate an unusually high spatial homogeneity of annual precipitation curve shape in Minnesota. The generalized shape accounts for about 99 per cent of the observed variance and meshes well with the overall pattern of the central United States. Interesting deviations do occur, however. These deviations suggest fundamental questions about precipitation-causing processes which should be investigated in the future.
