Cover of the La Niña Report
La Niña Report

The successive La Niña events of 2010–12 that contributed to record-breaking rainfall and cooler temperatures across Australia, particularly eastern Australia, have been chronicled in a new Bureau publication.

The 24-page booklet and online publication Record-breaking La Niña events gives an insight into how La Niña (and El Niño) events occur and why they change Australia’s weather and climate. It also details the significant impacts of the 2010–12 La Niña events.

New streamflow forecasts for Queensland

New streamflow forecast locations

Streamflow forecasts are now available for nine sites in Queensland. Five new locations have been added in New South Wales, taking the total number of forecast sites to 50.

Current streamflow forecasts are favouring near median or high flows for most forecast sites except for low flows at four locations in the Murrumbidgee, Upper Murray and Ovens basins. As climate indicators continue to show a shift towards El Niño conditions, this may affect the streamflow forecasts for spring.

Amendments to Water Regulations 2008

On 10 May 2012, the Governor-General amended the water information provisions of the Water Regulations 2008.

Changes have been made to each of the ten water information categories to enhance the quality and usefulness of water information received by the Bureau.

Most of the changes will take effect on 5 July 2012, except for the amendment relating to a new Person Category (Category J – Owners or Operators of Hydrologically Significant Sites) which will not come into effect before 2013.

The amendments were drafted following consultation undertaken in 2011. Many of the comments received through this consultation were incorporated into the amendments.

Known as the Australian Climate Observations Reference Network – Surface Air Temperature (ACORN-SAT) the new dataset was developed to monitor and analyse long-term climate variability and change in Australia.
