    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, and eastern Australia.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 29 September to 3 October, 19 October to 23 October, and 24 October to 28 October. Rain events originating in the tropics and moving south are possible about 27 September to 1 October, 1 October to 5 October, and 15 October to 19 October. Over Western Australia the strongest cold fronts should occur about 30 September to 4 October, 18 October to 22 October, and 24 October to 28 October.

    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 Sep 9

    ENSO status: La Niña Alert IOD status: Negative SAM status: Negative trending positive Sea surface temperatures (SSTs) across the equatorial central Pacific have continued to cool through August, with the Nino3.4 index registering a value of -0.5. The Southern Oscillation Index (SOI) recorded a value of 9.8 in the same month, a significant increase compared to July, tipping over the La Niña threshold of +7. The current outlook suggests that cooler than average SSTs will continue across the equatorial pacific during the Austral spring, with a high chance of a weak La Niña forming. All eight international models continue to suggest further cooling during spring, with three of these indicating La Niña conditions in September. A further two exceeding the La Niña threshold in October, with six of the eight indicating La Niña by November. The current International Research Institute for Climate and Society (IRI) outlook suggests a 57:41 chance for La Niña:Neutral conditions by the end of the Australspring. To the west of Australia, the Indian Ocean Dipole (IOD) has shifted into a negative phase. Four of the six international models indicate a negative IOD to be sustained for the duration of the Austral spring, with the remaining two indicating a neutral phase. Both of the models that indicate a neutral phase trend towards the negative side of neutral. In terms of precipitation over Australia, the current short term outlook favours above average rainfall over the interior over the remainder of the first month of spring, particularly eastern WA and the Kimberley, western NT and western SA Above average rainfall is also favoured, although not as pronounced, over inland NSW and QLD and parts of the NSW and VIC coastal area. Drier than average conditions are expected across western WA as well as parts of northern coastal QLD and parts of the southeast. The remainder of spring is then likely to be wetter than average for NSW, QLD, VIC, SA, TAS, the NT and eastern WA, whilst drier than averageconditions look to persist further west. There are then indications of increased rainfall over WA toward the end of spring and into early summer, with the eastern two thirds of the country remaining wetter than average.
