    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 South Africa, the Indian Ocean, eastern Australia, the south 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 11 March to 15 March, 20 March to 24 March, and 24 March to 28 March. Rain events originating in the tropics and moving south are possible about 6 March to 10 March. Over Western Australia the strongest cold fronts should occur about 4 March to 8 March, 11 March to 15 March, and 25 March to 29 March.

    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 Feb 12

    ENSO status: Neutral IOD status: Neutral SAM status: Trending neutral Sea surface temperatures (SSTs) across the equatorial central Pacific remained stable throughout January with the Nino3.4 index registering a value of 0.4 as per December. On the other hand, the Southern Oscillation Index (SOI) recorded a value of 1.3 in January. The current outlook suggests warmer than average SSTs will persist across the equatorial Pacific Ocean through the austral autumn, cooling even further by mid 2020. Six out of eight international models continue to maintain a warmer than average equatorial Pacific Ocean through the first half of the year, none of these reaching El Nino thresholds. To the west of Australia, the Indian Ocean Dipole (IOD) remains neutral, which is what you will expect for this time of the year. All six international models maintain neutral IOD values until the austral winter, with indications we could see another positive event late winter/spring. However, the skill of the models is low at this time of the year. In terms of rainfall across Australia, the current outlook favours average-to-below average rainfall for parts of inland NSW and Qld for the end of summer and autumn. This however, excludes any extreme weather events such as tropical cyclones or East Coast Lows. Across the north, the North Australian Monsoon (NAM) had its latest onset on record in early February at Darwin (by its technical definition) with the current prognosis suggesting another below average wet season for northern Australia. The northern half of the country however, could see a wet end to the wet season compared to the season thus far. Looking further ahead, with no significant signature from ENSO, there are no significant climate drivers tilting the balance towards a drier or wetter end of autumn/winter.
