    Issue Notes

    The hemispheric long wave pattern has remained stable in recent weeks. There are seven main troughs. Currently the most significant troughs are near the longitudes of South Africa, the southwest Indian Ocean, the Indian Ocean, New Zealand, the southeast Pacific, South America, and the Atlantic Ocean.

    Summary:

    Over southern and eastern Australia the cold front events with potential to bring widespread rain are now expected about 19 August to 23 August, 24 August to 28 August, and 29 August to 2 September. Rain events originating in the tropics and moving south are possible about 12 August to 16 August, 19 August to 23 August, and 25 August to 29 August. Over Western Australia the strongest cold fronts should occur about 11 August to 15 August, 16 August to 20 August, and 23 August to 27 August.

    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 Aug 5

    ENSO status: La Nina Watch IOD status: Neutral SAM status: Positive Sea surface temperatures (SSTs) across the equatorial central Pacific show a slight decrease in the intensity of cooling compared to June, with the Nino3.4 index registering a value of 0.0 in July. The Southern Oscillation Index (SOI) recorded a value of 4.2 in the same month, a swing into positive values compared to June. The current outlook suggests that cooler than average SSTs will continue across the equatorial pacific through the end of winter and potentially reach La Nina thresholds by mid-spring. All eight international models continue to suggest a cooler side of neutral for the region throughout the remainder of the Austral winter and through spring, with four of these indicating La Nina by Spring. The current International Research Institute for Climate and Society (IRI) outlook suggests a 54:41 chance for La Nina:Neutral conditions by the end of the Austral spring. To the west of Australia, the Indian Ocean Dipole (IOD) remains neutral. Two of the six international models indicate a negative IOD becoming established during the Austral spring, with the remaining four indicating a neutral phase. Of the four neutral models, including the BOM, three are trending slightly negative within the neutral zone by early spring, with only the Canadian model trending positive. In terms of precipitation over Australia, the current short-term outlook favours above average rainfall across most of Australia over the next fortnight, with the exception of western TAS, far southern VIC, and northern QLD and the NT. These expected wetter than average conditions will likely be due to the passage of moisture troughs inland and fronts, in part driven by the positive SAM. Models are then indicating a continued trend to above average rainfall for inland SA, all but the far north of the NT, western, central and southern QLD, northern and western NSW and parts of southern WA. Parts of WA’s Pilbara and Kimberley however are showing signs of below average rainfall into early spring.
