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 ...
Each had until 2018 a range of 256 km (159 mi) in radius around the site to detect reflectivity, 3 angles with a range of 128 km (80 mi), for detecting velocity pattern (Doppler effect), and an extra long range up to 240 km (150 mi) at low elevation angle but strongly folded or aliased (where the maximum unambiguous velocity interval (±Vmax ...
The Bureau of Meteorology (BOM or BoM) is an executive agency of the Australian Government responsible for providing weather services to Australia and surrounding areas. It was established in 1906 under the Meteorology Act, and brought together the state meteorological services that existed before then. [ 3 ]
NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The Bureau of Meteorology noted that "Kalgoorlie Doppler Radar image at 0725 UTC (1525 AWST) showed a pixel which had an inbound velocity of around 110 km/h at a height of ~487 metres above the ground (aliased: 22.5 m/s outbound)" in the tornado record for this event.

According to Australia's Bureau of Meteorology, one of the country's most significant tropical cyclones was Cyclone Tracy in 1974, which killed 71 people in Northern Territory. Early on December 25 (local time), Cyclone Tracy struck the territory capital of Darwin , where it produced a wind gust of 217 km/h (135 mph) before the anemometer at ...
On 1 January, the Bureau of Meteorology (BOM) reported that a tropical low had formed near Groote Eylandt in the western Gulf of Carpentaria, located about 635 km (395 mi) east-southeast of Darwin. [99] The system was assigned the identifier code 05U by the BOM. [100]
