    Issue Notes

    The hemispheric long wave pattern has remained stable in recent weeks. There are four main troughs. Currently the most significant troughs are near the longitudes of South Africa, the Indian Ocean, New Zealand, and South America.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 24 May to 28 May, 6 June to 10 June, and 17 June to 21 June. Rain events originating in the tropics and moving south are possible about 22 May to 26 May, 1 June to 5 June, and 18 June to 22 June. Over Western Australia the strongest cold fronts should occur about 24 May to 28 May, 9 June to 13 June, and 17 June to 21 June.

    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 May 11

    ENSO status: La Niña, it is expected return to neutral state by early winter. IOD status: Neutral, models suggest it could enter a negative phase in the next month. SAM status: Positive and is expected to remain positive for the next month or so. The El Niño–Southern Oscillation (ENSO) is in a La Niña phase and has not changed in strength during the past two weeks. La Niña events typically breaks down in autumn and while this current La Niña is persisting longer than usual, most models suggest it should end by early winter. However, one seasonal model operated by the U.S. National Weather Service’s Climate Prediction Centre (CPC) suggests that a La Niña-like signal could linger in the Pacific Ocean through the middle of the year and possibly remerge in the Southern Hemisphere’s spring. That being said, it is important to note that seasonal forecast models have lower accuracy at this time of year. This is called the autumn predictability barrier. The La Niña forecast will increase the likelihood of above-average rain in northern and eastern Australia during the remainder of Autumn, possibly into winter. Even as La Niña weakens it should continue to influence our climate. all five climate models suggest a negative phase will begin during late autumn or early winter. Climate models are forecasting strong negative IOD values by August, with the negative IOD event possibly lingering into spring. While a neutral IOD has little influence on our climate, a negative IOD increases the chance of above average autumn and winter rain for much of Australia. The rainfall outlooks are reflecting this, with above average rain forecast during winter for much of Australia, except southwest WA, parts of TAS and VIC. If a negative IOD does develop this winter, it will increase the risk of flooding over large areas of inland Australia, especially areas that had a wet summer and autumn.
