Australia's weather radars

(Redirected from Australian Weather Radars)

The majority of Australia's weather radars are operated by the Bureau of Meteorology (BoM), an executive agency of the Australian Government. The radar network is continually being upgraded with new technology such as doppler and dual polarisation to provide better now-casting. Doppler weather radars are able to detect the movement of precipitation, making it very useful in detecting damaging winds associated with precipitation,[1] and determining if a thunderstorm has a rotating updraft, a key indicator of the presence of the most dangerous type of thunderstorm, a supercell.[2][3][4]

The new dual polarisation radars give forecasters the ability to:

  • detect debris in the atmosphere, leading to more accurate tornado warnings;[5]
  • distinguish between different precipitation types, leading to better estimations of hail size and severity;[5]
  • better identify areas of heavy rainfall, leading to more accurate flood warnings;[6] and
  • discern between precipitation and non-meteorological echoes such as chaff, birds, and insects.[5]

The dual polarisation transition

edit

The transition to polarimetric (dual-polarised) radars began in 2017 with the upgrade of 4 Meteor 1500 radars located in Melbourne, Brisbane, Adelaide, and Sydney.[7] The network has further been enhanced through the installation of 8 new polarimetric Meteor 735 radars across WA,[8] NSW[9] & Victoria,[10] and two polarimetric WRM200 radars[11] manufactured by Vaisala, one to replace the radar in Dampier, WA which had been destroyed by severe tropical cyclone Damien in 2020, and one to replace an ageing radar near Gove in the Northern Territory. Six new Meteor 1700s were also installed between 2021 and 2023, 5 located in Qld,[12] and 1 in Perth, WA,[8] all equipped with dual polarisation technology. All the radars with the model name 'Meteor' were manufactured by Selex ES, now Leonardo.

Specifications are available for the Meteor 735, Meteor 1700, and the Vaisala WRM200.

The BoM retrofitted it with modern parts which gave it the unique ability to collect data at two frequencies, S and X band. The upgrades also provided state of the art dual polarisation and doppler technologies. The CP in its title stands for cloud physics, and the radar has been used to research thunderstorms, drive improvements in rainfall measurements and hail detection and explore the potential for cloud seeding.[36]
Ocean Pol N/A (Mobile radar) 22m Active (22/3/2015-) N/A C   Yes   Yes This research radar is installed on the RV Investigator, an ocean research vessel. The radar collects data on research voyages, including trips to Antarctic waters, Heard Island and circumnavigations of Australia.[37]
UQXPOL[38] N/A (Mobile radar) N/A Active (14/10/2014-) Furuno WR-2100 X   Yes   Yes This research radar is operated by the University of Queensland and has been involved with research to improve hail detection and hail size prediction algorithms,[39] and also with research into bushfires and pyroconvection as part of a $1 million google.org philanthropic venture.[40][41]
