Sydney has a new state-of-the-art weather radar that will help forecasters and the community see in greater detail upcoming weather – including severe weather such as thunderstorms.

The Doppler weather radar was launched today at Terrey Hills by Australia’s Director of Meteorology, Dr Greg Ayers.

The new radar is more sensitive and uses the latest technology to provide clearer radar images at a higher resolution than previously possible. It replaces one that has been operating at Appin, south of Sydney since 1992.

Commissioning the radar, Dr Ayers noted the significance of its range which spans Sydney and surrounding areas – “an area that is home to more than a quarter of the Australian population.”

“Weather radars play an important role in helping the community prepare for and manage the threats posed by extreme weather.”

The Bureau’s Regional Director for New South Wales, Barry Hanstrum said the improved capability offered by this new radar will help forecasters “more easily detect and track thunderstorms in the Sydney area and detect dangerous wind changes during the fire season.”

The new radar animation, covering the previous half hour’s weather, now consists of six images, one every six minutes where as previously it was just four images. “This upgrade will certainly provide a new level of detail about weather in the Sydney area,” Mr Hanstrum said.

“The greater sensitivity of the radar will also assist in better detection of drizzle and light shower activity over Sydney.”

This new Doppler weather radar is the fifth of six new high resolution radars to come online as part of the Australian Government’s $62.2 million dollar radar upgrade project.

Recently the Government announced a further $48 million program to install four new radars around Australia as well as invest in the underlying science to integrate this technology into the current radar network. Imagery from the Bureau’s network of weather radars is available on the Bureau of Meteorology website www.bom.gov.au
