Since 1979 many districts in E. Rajasthan have experienced deficit rainfall year after year. To understand the phenomenon of below normal rainfall for more than 2 years in succession in many districts, a statistical study of rainfall data from 7 contiguous districts in E. Rajasthan was undertaken. Besides tests for randomness, trend analysis by linear and polynomial regression were attempted. Rainfall in the non-monsoon season had no relationship with preceding monsoon season rainfall. The serial correlation (nearly zero) indicated no persistence. There was no curvilinear trend although some stations in each of the districts showed some linear trend.
