    Issue Notes

    The hemispheric long wave pattern has remained stable in recent weeks. There are five main troughs. Currently the most significant troughs are near the longitudes of the southwest Indian Ocean, Western Australia, the south Pacific, 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 30 June to 4 July, 21 July to 25 July, and 25 July to 29 July. Rain events originating in the tropics and moving south are possible about 22 June to 26 June. Over Western Australia the strongest cold fronts should occur about 29 June to 3 July, 3 July to 7 July, and 21 July to 25 July.

    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 Jun 15

    ENSO status: Neutral. IOD status: Neutral, although during the past three weeks it has been negative. SAM status: Positive. The El Niño–Southern Oscillation (ENSO) is currently neutral, which is predicted to continue until at least October. The Indian Ocean Dipole (IOD) is currently neutral. although the last 3 weekly values have been negative.The negative value would need to continue for another 5 weeks for a negative IOD to be declared. While a negative IOD has not been officially declared, the negative weekly value may enhance rainfall across central and southern Australia. A negative IOD is forecast during winter or early spring by 3 out of 5 climate models. However, the confidence in the IOD forecast at this time of the year is low, specifically because the models are showing a range of outcomes from mid winter onwards. During winter, much of the Australia is likely to be wetter than normal, apart from far southern WA and SA, southern VIC and much of TAS. The weekly negative IOD valuesmay 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 western TAS. Again, the negative IOD values may be playing a role in this outlook.
