The El Niño-Southern Oscillation (ENSO) remains neutral, with virtually all indicators at near-normal levels. Only cloudiness near the Date Line shows a weak La Niña-like signal. International climate models surveyed by the Bureau of Meteorology indicate that the tropical Pacific will remain ENSO-neutral for the remainder of 2013. Only one of the seven models surveyed suggests a brief period of La Niña-like cooling of the tropical Pacific.

The negative Indian Ocean Dipole (IOD) event has weakened considerably over the past month and a half, with IOD-neutral values prevailing since early August. The consensus of climate models is for the IOD to remain neutral for the remainder of the year, suggesting that the 2013 negative IOD is most likely at an end. >> More
