El Niño events were suggested as a potential predictor for malaria epidemics in Sri Lanka based on the coincidence of nine out of 16 epidemics with El Niño events from 1870 to 1945. Here the potential for the use of El Niño predictions to anticipate epidemics was examined using enhanced climatic and epidemiological data from 1870 to 2000. The epidemics(More)
columbi Summary We investigate the viability of using El Niño–Southern Oscillation (ENSO) and sea surface temperature (SST) data to predict seasonal streamflow for one of the major rivers in Sri Lanka, the Kelani, using correlation analysis, contingency tables, and principal component analysis. The agricultural seasons in Sri Lanka are Yala(More)
El Niño-Southern Oscillation (ENSO) is a dominant mechanism of global inter-annual climate variability. In this study, the relationship of ENSO to seasonal rainfall over 139 years is described. Ranking both, the seasonal Sri Lankan rainfall and its contemporaneous ENSO index show modest but significant association in January-March, May and JulyAugust and(More)
