Abstract

A detailed examination has been made of the relationship between the space and time variations of the Indian summer monsoon rainfall and the equatorial eastern-Pacific sea surface temperature (SST) anomaly in different seasons for the 108-year period, 1871-1978. There is a strong inverse relationship between the two. The correlation coefficients between All-India monsoon rainfall and the sea surface temperature anomaly for the concurrent season; June, July and August (JJA) and for the succeeding seasons; September, October and November (SON) and December, January and February (DJF) are consistently and highly significant. Even a random sample of 50 years gave values significant at the 0.1 percent level. The sliding window correlation analysis of 10-, 20- and 30-year widths indicates that the relationships between All-India monsoon rainfall and the sea surface temperature anomaly for the concurrent JJA and the succeeding SON and DJF seasons exhibit stability and consistency in significance. For contiguous meteorological sub-divisions west of longitude 80°E the relationship is highly significant for JJA and for succeeding SON and DJF seasons.
