    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 the southwest Indian Ocean, eastern Australia, the south Pacific, the southeast 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 6 December to 10 December, 16 December to 20 December, and 1 January to 5 January. Rain events originating in the tropics and moving south are possible about 7 December to 11 December, 11 December to 15 December, and 19 December to 23 December. Over Western Australia the strongest cold fronts should occur about 6 December to 10 December, 16 December to 20 December, and 20 December to 24 December.

    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 Nov 11

    ENSO status: La Niña IOD status: Neutral SAM status: Positive La Niña is well underway in the central and eastern equatorial Pacific waters, with significant cooling observed during the last few months. The atmospheric and ocean conditions have both exceeded La Niña thresholds, increasing the confidence of La Niña influencing the outlook until at least the remainder of summer. The majority of models predict that La Niña will peak in December or January, with all models predicting the event will last until January, 6 of 8 models to February and 5 of 8 to March. Given we have observed both the atmosphere and the oceans responding to La Nina, the models have strengthened the event, with around half of the models predicting a strong event. The 2010-2012 La Niña event is different to this year, due to the influence of a negative Indian Ocean Dipole (IOD) in 2010-2012, which enhanced the rainfall across Australia. To the west of Australia, the Indian Ocean Dipole (IOD) is neutral, which is likely tocontinue through to at least autumn. Two of six international models indicate a negative IOD during November, before becoming neutral in December. La Niña typically favours periods of positive SAM, which can increase the amount of precipitation along the eastern half of the country, due to prevailing onshore winds. La Niña increases the likelihood of above normal precipitation in spring and summer across much of Australia. The remainder of spring looks wetter than normal for much of Australia, except for parts of western WA and western TAS, where normal precipitation is expected. During summer, much of the country is likely to remain wetter than normal including western WA during these months. Western TAS precipitation outlook continues to be normal through summer. La Niña typically increases the number of cyclones and brings an early start to the northern wet season.
