    Issue Notes

    The hemispheric long wave pattern has been relatively fast moving in recent weeks. There are three main troughs. Currently the most significant troughs are near the longitudes of South Africa, Western Australia, and the south Pacific.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 22 January to 26 January, 31 January to 4 February, and 5 February to 9 February. Rain events originating in the tropics and moving south are possible about 8 February to 12 February. Over Western Australia the strongest cold fronts should occur about 22 January to 26 January, 31 January to 4 February, and 5 February to 9 February.

    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 Jan 14

    ENSO status: Neutral IOD status: Neutral SAM status: Trending neutral Sea surface temperatures (SSTs) across the equatorial central Pacific remained stable throughout December with the Nino3.4 index registering a value of 0.4 throughout the month. On the other hand, the Southern Oscillation Index (SOI) recorded a value of -5.5 in December. The current outlook suggests warmer than average SSTs will persist across the equatorial Pacific Ocean through the coming months, but remaining within neutral values. Six out of eight international models maintain a warmer than average equatorial Pacific Ocean through the first two quarters of 2020, none of these reaching El Nino thresholds. To the west of Australia, the Indian Ocean Dipole (IOD) has now returned to neutral, as waters off Western Australia have warmed up considerably. All six international models maintain neutral values until the austral winter with indications we could see another positive event later this year. In terms of rainfall across Australia, the current outlook favours a clearer below average rainfall signal for Western Australia and the Northern Territory through the remainder of January. This however, excludes any extreme weather events such as tropical cyclones. For the eastern states, there is a wetter than average signal for the coming weeks. Looking further ahead, with no significant signature from ENSO, there are no significant climate drivers tilting the balance towards a drier or wetter February. The current outlook suggests average-to-below average odds for February and March across the eastern states. The northern and western half of the country, however, could see a wet end to summer/start to autumn.
