Multi-week forecasts, which are top of the list for the Managing Climate Variability (MCV) program, have come a step closer with the Bureau of Meteorology (BoM) switching to dynamical, or physics-based, forecasting... MCV program manager Dr Beverley Henry says statistical systems, while still having a role, are becoming less reliable because climate change has made recent years a poor indicator of future weather patterns... Dr Henry says that longer-term forecasting will always be a challenge, given the element of chaos in weather systems, but technological advances now allow the MCV program to provide growers with intelligence that is reliable enough to help with climate risk management...

For a La Ni a to develop, the relatively high-frequency fluctuations of SOI, winds and ocean temperatures would need to stop and be replaced by a period of consistently stronger-than-average trade winds, positive SOI values and further cooling of the ocean... Although July 2007 was wetter than July 2006 in western WA, Victoria and south-east SA, and there was a slight easing of 12-month deficits in those regions, south-east Queensland, Tasmania and the Eyre Peninsula experienced a drier July this year... A large part of south-east Queensland was also affected, as were Tasmania (except for the south-west) and parts of western WA between Carnarvon and Perth, as well as areas between Wagin and Albany...

Good early season rainfall in south-east Australia in 2007 indicated the break-down of the dry conditions in 2006 which were caused by a weak El Nino together with a positive Indian Ocean Dipole (IOD)... History is of little use in terms of the transition from the La Nina/+IOD of 2007... The MJO can be monitored in real-time [14], and a useful commentary is provided by APSRU [15]...
