    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, Western Australia, New Zealand, and the southeast Pacific.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 10 April to 14 April, 16 April to 20 April, and 5 May to 9 May. Rain events originating in the tropics and moving south are possible about 16 April to 20 April. Over Western Australia the strongest cold fronts should occur about 11 April to 15 April, 17 April to 21 April, and 5 May to 9 May.

    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 Mar 9

    ENSO status: Neutral IOD status: Neutral SAM status: Trending neutral Sea surface temperatures (SSTs) across the equatorial central Pacific remained stable throughout February with the Nino3.4 index registering a value of 0.3. On the other hand, the Southern Oscillation Index (SOI) recorded a value of -2.2 in February. The current outlook suggests slightly warmer than average SSTs will persist across the equatorial Pacific Ocean through the austral autumn, potentially cooling further by the austral winter. Four out of seven international models maintain a slightly warmer than average equatorial Pacific Ocean through the first half of winter. To the west of Australia, the Indian Ocean Dipole (IOD) remains neutral, normal for this time of the year. All six international models maintain neutral IOD values through to the austral winter. In terms of precipitation across Australia, the current outlook favours below average rainfall for western, central and southeastern parts of the country. Across NSW and Qld, the outlook is for average-to-above average, mainly across the Qld coasts. This excludes any extreme weather events such as tropical cyclones or East Coast Lows. Across the north, the North Australian Monsoon (NAM) has been quiet for most of the wet season, with the current prognosis suggesting below average rainfall for March but above average in April. 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. The current consensus, however, suggests that average to above average rainfall is a possibility across northern, western and parts of the inland south east.
