“…The relationship between the El Niño-southern oscillation (ENSO) and variations in Indian summer monsoon rainfall (SMR) has been demonstrated by many studies (Troup, 1965;Sikka, 1980;Angell, 1981;Pant and Parthasarathy, 1981;Mooley and Parthasarathy, 1983;Bhalme et al, 1983;Carpenter, 1982, 1983;Shukla and Paolino, 1983;Parthasarathy and Pant, 1985;Gregory, 1989;Webster and Yang, 1992;Webster et al, 1998).
