Abstract

Daily rainfall data for the winter season October–December for the long period of 102 years 1901–2002 over southeast peninsular India have been used to study the characteristics of daily precipitation extremes. The frequency and intensity of extreme precipitation events do not show statistically significant long‐term trend. The relationship of El Nino‐southern oscillation index with these extremes shows that this index can be used to predict frequency and intensity of extreme precipitation events, 4–6 months in advance. However spell lengths of continuous wet/dry days are not modulated by variations in Pacific sea surface temperatures. Copyright © 2007 Royal Meteorological Society

## Abstract El Niño and La Niña are well known to be associated with significant monthly/seasonal climate anomalies at many places around the globe. Therefore, an attempt is made in this study to analyse objectively defined indices of observed temperature extremes over India, in terms of their freq

By means of a statistical study of percentiles, applied to bi-monthly seasons of composite 2-year periods centred in the year of occurrence of a warm or cold ENSO extreme, we show the climatic influence of these events on the western Mediterranean area. The study is developed over a 30-year period .
