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 ...
201 mph (323 km/h) A Doppler on Wheels observed the tornado through its entire life. The radar recorded winds of 100 mph (160 km/h), 145 mph (233 km/h), and 201 mph (323 km/h) at various heights ranging from 3–50 m (9.8–164.0 ft). [29] F0 June 15, 2005: Trego Center, Kansas — — — A Doppler on Wheels observed the tornado in an open field.

[1]This is a list of tornadoes which have been officially or unofficially labeled as F5, EF5, IF5, T10-T11, the highest possible ratings on the various tornado intensity scales.
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.).
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 ]
However, winds of 309–318 mph (497–512 km/h) were measured in a sub-vortex of the tornado by a DOW (Doppler on Wheels), placing it among the strongest tornadoes ever measured. [ 3 ] This tornado was the fourth violent tornado of the 2024 season and the second one to occur during the prolifically active month of May.
