    Issue Notes

    The hemispheric long wave pattern has been relatively slow moving in recent weeks. There are five main troughs. Currently the most significant troughs are near the longitudes of South Africa, Western Australia, New Zealand, the south Pacific, and South America.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 9 August to 13 August, 23 August to 27 August, and 2 September to 6 September. Rain events originating in the tropics and moving south are possible about 22 August to 26 August, 3 September to 7 September, and 7 September to 11 September. Over Western Australia the strongest cold fronts should occur about 9 August to 13 August, 14 August to 18 August, and 18 August to 22 August.

    Forecast Explanation

    This forecast is produced by a multi-model ensemble consisting of dynamical atmospheric models, which are forced by the latest observed atmosphere, ocean, land and ice conditions. The models are designed to simulate features of the real atmosphere, including the daily movement of long and short wave patterns in the Southern Hemisphere.

    The future probability of rain in each district is estimated using output from the multi-model ensemble, combined with historical information about the difference between the model forecasts and observed rainfall.

    In this deterministic framework the skill of the forecast tends to decrease with time, however the forecasts are updated daily to provide the latest estimates of rainfall probability out to 28 days.

    Issue Notes - Issued Jul 13

    ENSO status: Neutral, however two models suggest La Niña thresholds may be met again from September. IOD status: Neutral, although it was negative for six weeks between mid-May and late-June SAM status: Negative. The El Niño–Southern Oscillation (ENSO) is currently neutral. However, there are growing signs that La Niña could redevelop in the Pacific Ocean later this year, prompting the US Climate Prediction Centre to issue a La Niña Watch this week. Two models forecast temperatures reaching the La Niña threshold during September. The Indian Ocean Dipole (IOD) is currently neutral, although we saw six consecutive weeks below the negative IOD threshold between mid-May and late-June. The IOD index needs to stay below -0.4C for eight consecutive weeks to be officially declared as a negative IOD event. The IOD ducked back into neutral territory thanks to recent warming in the western Indian Ocean. While a negative IOD has not been officially declared, the negative weekly values may enhance rainfallacross central and southern Australia. Three of the five models are forecasting the negative IOD to develop in winter, with another one indicating development in early spring. Most of the models suggest that the negative IOD will continue through until mid spring. During winter, much of the Australia is likely to be wetter than normal, apart from far southern WA and SA, southern VIC and southwestern TAS. The weekly negative IOD values may be influencing this outlook, potentially feeding moisture into cold fronts sweeping across central and southern Australia. Therefore a normal to above normal snow season is forecast. Springs rainfall at this stage is forecast to be above normal for much of the Australia, apart from southwestern TAS and WA. Again, the negative IOD values may be playing a role in this outlook.
