Abstract

The average rainfall series of Tamil Nadu for the northeast monsoon months of October to December and the season as a whole were analysed for trends, periodicities and variability using standard statistical methods. The trend analysis showed that there are no long‐term trends of increasing or decreasing rainfall in the individual months or the season as a whole. The power spectrum analysis of rainfall series showed peaks at frequencies corresponding to the time periods of 2 to 2–44 years and 3–66 to 4–40 years.
