    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, Western 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 17 July to 21 July, 29 July to 2 August, and 5 August to 9 August. Rain events originating in the tropics and moving south are possible about 31 July to 4 August. Over Western Australia the strongest cold fronts should occur about 17 July to 21 July, 30 July to 3 August, and 6 August to 10 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 Jun 15

    ENSO status: Neutral IOD status: Neutral SAM status: Trending positive Sea surface temperatures (SSTs) across the equatorial central Pacific exhibited significant cooling over the past month, with the Nino3.4 index registering a value of -0.1in May. On the other hand, the Southern Oscillation Index (SOI) recorded a value of 2.8 during the same month. The current outlook suggests cooler than average SSTs will take hold across the equatorial Pacific Ocean during winter, potentially reaching 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. The current International Research Institute for Climate and Society (IRI) outlook suggests a 45:40 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, normal for this time of the year. However, out of season Tropical CycloneMangga brought some significant cooling to the sea surface temperatures to the northwest of Australia late in May. This disrupted the warming trend in the region that would have led to a negative IOD by mid-winter. Nonetheless, all but one of the six main international models (BoMs outlook), continue to hint at a possible negative IOD establishing later in winter/first half of spring. In terms of precipitation across Australia, the current short-term outlook now favours below average rainfall for most of the country for the remainder of June and early July. This outlook is mainly driven by cooler SSTs across northwestern Australia, reducing the amount of available moisture in the atmosphere. As discussed earlier, tropical cyclone Mangga was a key player in the cooling of the SSTs off the northwest coast. Most models, however, are indicating a positive IOD is still on the cards later in winter and through spring, bringing a wetter outlook for most of the southern half of the country from mid-to-lateJuly. Across parts of southern Vic, NSW and Qld (east of the Great Dividing Range), southwestern WA and Tasmania, the outlook continues to favour 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 Tas) but more on the phases of the Southern Annular Mode (SAM).
