Latest wrap-up from BOM ENSO expected to remain neutral at least through autumnIssued on Tuesday 11 February 2014 | Product Code IDCKGEWWOO The El Niño–Southern Oscillation (ENSO) state is neutral, with climate models suggesting neutral conditions will persist at least until the end of the austral autumn. However, some warming of the Pacific is likely in the coming months. Most international climate models surveyed by the Bureau suggest the tropical Pacific Ocean will warm through the austral autumn and winter. Some, but not all, models indicate central Pacific Ocean temperatures may approach El Niño levels by early winter. Model outlooks that span autumn tend to have lower skill than outlooks made at other times of the year, hence long-range outlooks should be used cautiously at this point. Neither neutral nor El Niño states can be discounted for the second half of 2014. In the last fortnight, a westerly wind event over the far western tropical Pacific led to some warming beneath the surface of the tropical Pacific Ocean, though surface temperatures remain close to average. The current high values of the SOI are expected to reduce as recent volatile weather near Darwin and Tahiti eases. The Indian Ocean Dipole is typically too weak to have a significant influence on the Australian climate from December to April. http://www.bom.gov.au/climate/enso/
