Abstract

In the present study the empirical orthogonal function or 'eigenvector' approach is used to determine the dominant rainfall patterns from normal seasonal rainfall records over Rajasthan. Two contrasting years (1917 and 1918) in which rainfall was in excess and deficient are also examined separately to see what anomalies, if any, exist in the associated patterns. In the years of normal rainfall the first eigenvector is found to account for 99 of the variance in the original 12 x 40 matrix of rainfall data. However, in years of excessive or deficient rainfall, 3 or 4 vectors are needed to account for 99 of the variance. -from Authors
