A key factor why the current El Nino episode found immense difficulty in establishing itself was the lack of coupling between the Sea Surface Temperatures (SSTs) found in the Nino region of the Central Pacific and the atmosphere. Because of this, doubts were even cast whether any El Nino would be experienced this year as Nino STTs and Southern Oscillation Index (SOI) demonstrated diametrically opposite trends – SSTs signalling an El Nino while SOI signalling La Nina.
The Japanese climate agency, JAMSTEC model predictions, if they actualize doesn’t augur too well at all for the Indian monsoon. They predict a double whammy – a combined El Nino-Indian Ocean Dipole adverse effect. If so, we may end up facing a seasonal rainfall deficiency at least within 20-30% range, if not more. Our current rainfall deficiency stands at over 45% and the month of June may end with 50% plus deficiency. If JAMSTEC is right, then July-Sept may fare no better.
