Yellows represent warmer than normal waters (seasonally adjusted)/Blues are cooler than normal

Lower panel: West-to-east winds and warmer than normal water temps are indicative of El Nino

Kelvin waves are evidenced by pockets of warmer than normal water at the 200m depth. Over time they travel slowly west to east, rising to the surface in the far East Pacific as they impact the South American coast.

Southern Oscillation Index

Measures the relative surface pressure difference between Darwin Australia and Tahiti. Consistently negative values indicate El Nino, positive values La Nina. Short negative spikes are associated with the active phase of the MJO. Continual active MJO events contribute greatly to the SOI and each individual event can generate westerly wind bursts that result in Kelvin Waves.

Negative values represent increased clouds (more sun radiation absorption)/Positive values indicate less clouds (more reflection) and the inactive phase. Broad areas of negative values over the equatorial Pacific tracking from the Indian Ocean in to the Western Pacific are normally associated with the active phase of the MJO. Also broad negative values can establish themselves over warm water associated with a developing El Nino.

Negative values represent increased clouds (more sun radiation absorption) and an active phase of the MJO/Positive values indicate less clouds (more reflection) and the inactive phase

Positive values represent anomalous winds blowing west-to-east/Negative values indicate increased trades and the inactive phase
