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.
