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 ...

Berrimah radar The Bureau of Meteorology is the main provider of weather forecasts , warnings and observations to the Australian public. The Bureau's head office is in Melbourne Docklands , which includes the Bureau's Research Centre, the Bureau National Operations Centre, the National Climate Centre, the Victorian Regional Forecasting Centre ...
Decibel relative to Z, Decibels of Z, or dBZ, is a logarithmic dimensionless technical unit used in radar. It is mostly used in weather radar, to compare the equivalent reflectivity factor (Z) of a remote object (in mm 6 per m 3) to the return of a droplet of rain with a diameter of 1 mm (1 mm 6 per m 3).

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.).
Radar image of the 2021 Sydney hailstorm at its peak intensity. On 14 October 2021, multiple severe thunderstorm formed over the blue mountains and quickly moved east towards Sydney. One particular storm boasted an impressive hook echo on radar, and doppler winds indicates the presence of a broad mesocyclone. As a result, the Bureau of ...
The frequency selection of weather radar is a performance compromise between precipitation reflectivity and attenuation due to atmospheric water vapor. Some weather radars uses doppler shift to measure wind speeds and dual-polarization for identification of types of precipitations. [3] [4] Weather radar; Wind profilers; Millimetre cloud radar ...
On 27 November 2024, after a nearly a week-long heatwave conditions in Sydney, where the City saw weather conditions more typical of January or February than in November. Sydney Airport warmed to 38.1 °C (100.6 °F) at 12:15pm, which made it the hottest place in the world at that time (a few reasons being due to the foehn effect and UHI effect).
