    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, the south Pacific, and South America.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 28 October to 1 November, 14 November to 18 November, and 19 November to 23 November. Rain events originating in the tropics and moving south are possible about 28 October to 1 November, 16 November to 20 November, and 25 November to 29 November. Over Western Australia the strongest cold fronts should occur about 29 October to 2 November, 16 November to 20 November, and 24 November to 28 November.

    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 Oct 8

    ENSO status: La Niña IOD status: Negative SAM status: Positive La Niña thresholds have been met due to continued cooling in the central and eastern equatorial Pacific waters in the last month. The atmospheric and ocean conditions have both exceeded La Niña thresholds, with the current Nino3.4 index registering a value of -0.68 and the Southern Oscillation Index is +9.5, now well over the La Niña threshold of +7. The majority of models predict that La Niña will peak in December, with all eight models predicting the event will last until January and 5 of 8 models to February. During this month’s model run, the strength of the La Niña event has increased since last month, however at this stage the event is not expected to be as strong as the 2010-2012 La Niña. To the west of Australia, the Indian Ocean Dipole (IOD) has shifted into a negative phase, which is likely to continue through October. Three of six international models indicate a negative IOD to be sustained for the duration of November, beforebecoming 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. The combination of La Niña and negative IOD conditions increase the likelihood of above normal precipitation in spring and summer across much of Australia. In terms of precipitation over Australia, the remainder of spring looks wetter than normal for much of Australia. However, normal to below normal precipitation is forecast for parts of western WA and western TAS. 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.
