    Issue Notes

    The hemispheric long wave pattern has been relatively fast moving in recent weeks. There are four main troughs. Currently the most significant troughs are near the longitudes of South Africa, the Indian Ocean, the southeast Pacific, and the Atlantic Ocean.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 7 October to 11 October, 13 October to 17 October, and 22 October to 26 October. Rain events originating in the tropics and moving south are possible about 5 October to 9 October, and 14 October to 18 October. Over Western Australia the strongest cold fronts should occur about 28 September to 2 October, 8 October to 12 October, and 14 October to 18 October.

    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 Sep 16

    ENSO status: Neutral, however five of seven models suggest La Niña thresholds may be met again between October and January. IOD status: Neutral, returning from negative values in the recent weeks. SAM status: Positive. 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, which has prompted the US Climate Prediction Centre to increase its prediction of La Niña occurring this year to 70-80 percent. However their thresholds are lower than the Bureau of Meteorology's. Five of seven models forecast temperatures may reach or exceed La Niña thresholds between October and January. Three of seven predicted an established event, which requires La Nina thresholds to be met for three months. La Niña typically brings above average rainfall in northern and eastern Australia. The Indian Ocean Dipole (IOD) is currently neutral, returning from negative values in the recent weeks. Three of five models areforecasting the IOD event will officially end in October, with all models ending the event in December. A negative IOD generates above average rain to southern and eastern Australia. As such, average to above average rainfall is predicted across much of the country this winter and spring.
