    Issue Notes

    The hemispheric long wave pattern has been relatively fast moving in recent weeks. There are five main troughs. Currently the most significant troughs are near the longitudes of South Africa, the southwest Indian Ocean, New Zealand, 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 20 June to 24 June, 25 June to 29 June, and 29 June to 3 July. Rain events originating in the tropics and moving south are possible about 8 June to 12 June, and 17 June to 21 June. Over Western Australia the strongest cold fronts should occur about 8 June to 12 June, 20 June to 24 June, and 29 June to 3 July.

    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 May 13

    ENSO status: Neutral IOD status: Neutral SAM status: Trending neutral Sea surface temperatures (SSTs) across the equatorial central Pacific remained stable throughout April with the Nino3.4 index registering a value of 0.5. On the other hand, the Southern Oscillation Index (SOI) recorded a value of -0.5 during the same month. The current outlook suggests slightly warmer than average SSTs will persist across the equatorial Pacific Ocean during the end of autumn and early winter, potentially cooling by the second half of the austral winter. Eight out of eight international models continue to suggest a cooling trend of the NINO3.4 region throughout the Austral winter, with all models on the cooler side of neutral by September. The current International Research Institute for Climate and Society (IRI) suggests a 40:35 chance for neutral:La Nina conditions by the Austral spring. To the west of Australia, the Indian Ocean Dipole (IOD) remains neutral, normal for this time of the year. All six main international models, however, continue to hint at a possible negative IOD establishing from mid-to-late winter. In terms of precipitation across Australia, the current medium term outlook continues to favour above average rainfall for most of the country. This outlook is mainly driven by warmer SSTs across northwestern Australia, enhanced soil moisture across some parts of the continent and early indications of a cool phase in the Pacific Ocean, which increases the moisture content across the northern tropics. Across parts of southern Vic, NSW and Qld (east of the Great Dividing Range), southwestern WA and Tasmania the outlook is for average-to-slightly below average rainfall over the coming months as these regions transition to their ‘drier’ part of the year (eastern seaboard) or tend to be less influenced by the IOD (SW WA and Tasmania) but more on the phases of the Southern Annular Mode (SAM). This doesn’t include any severe weather events like east coast lows.
