16. The following data sets were used in this study: (i) All-India summer (June to September) monsoon rainfall during 1856-1997 [B. Parthasarathy, K. Rupa Kumar, A. A. Munot, Theor. Appl. Climatol. 49, 217 (1994); N. A. Sontakke, G. B. Pant, N. Singh, J. Clim. 6, 1807 (1993)]. The equatorial Pacific (NINO3) SST anomalies during 1856-1997. NINO3 area (5°S-5°N and 150°W-90°W) SST anomalies were obtained from the grid-point data of A. Kaplan et al. [J. Geophys. Res. 103, 18567 (1998)] for the era 1856-1949, and those during 1950-1997 are taken from the Climate Prediction Center, Washington, DC (http://nic.fb4.noaa.gov/data/cddb/). The correlation between the two NINO3 series during the common period of 1951-90 is 0.97. (iii) Monthly velocity potential at 200 hPa during 1958-97 were obtained from the NCEP/NCAR reanalysis [E. Kalnay et al., Bull. Am. Meteorol. Soc. 77, 437 (1996)]. The 5° by 5° surface temperature anomalies on land as well as oceans during 1871-1997 [P. D. Jones, J. Clim. 7, 1794 (1994); D. E. Parker, C. K. Folland, M. Jackson, Clim. Change 31, 559 (1995)]. The anomalies are with respect to the 1961-90 climatology.

22. The rainfall and the NINO3 series are resampled [B. Efron, Ann. Stat. 7, 1 (1979)] 1000 times in random 21-year chunks. For each resample, the correlation between the rainfall and NINO3 series is computed. The 5th and 95th percentile of these 1000 correlation coefficients provide 95% confidence limits of -0.45 and -0.70, respectively. The correlations in the recent decades fall outside this range, indicating that the relationship in this period is significantly different from the rest of the record.

36. Model simulations [A. Kumar, A. Leetmaa, M. Ji, Science 266, 632 (1994)] reproduce the observed Eurasian warming in the recent decades when forced by global SSTs associated with strong and weak ENSO situations. However, the mechanisms for this link are not clear. A causal link in the opposite sense may also exist (15), where Eurasian snow cover anomalies may influence ENSO.
