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 ...
The Canadian weather radar network consists of 33 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each had until 2018 a range of 256 km (159 mi) in radius around the site to detect reflectivity, 3 angles with a range ...
A rare, violent, and deadly long-tracked tornado [1] [4] [5] struck several villages in the Hodonín and Břeclav districts of the South Moravian Region of the Czech Republic in the evening of 24 June 2021, killing six people and injuring 576 others. [6] [7] This tornado is the widest on record in Europe, at 3.5km maximum width. [1]
dBZ (meteorology) The scale of dBZ values can be seen along the bottom of the image. Decibel relative to Z, or dBZ, is a logarithmic dimensionless technical unit used in radar, mostly 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 ...
Radar is a system that uses radio waves to determine the distance ( ranging ), direction ( azimuth and elevation angles ), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
MétéoMédia. MétéoMédia is a Canadian French-language weather information specialty channel and web site owned by Pelmorex. MétéoMédia primarily serves viewers in Quebec, although some cable TV systems in Ontario and New Brunswick carry the channel as well. It is available nationwide via satellite. MétéoMédia went on the air along ...
Meteorologist. A meteorologist is a scientist who studies and works in the field of meteorology aiming to understand or predict Earth's atmospheric phenomena including the weather. [1] Those who study meteorological phenomena are meteorologists in research, while those using mathematical models and knowledge to prepare daily weather forecasts ...
The National Public Alerting System ( NPAS; French: Système national d'alertes à la population ), branded as Alert Ready ( French: En Alerte ), is the national warning system in Canada, broadcast to Canadian television, radio, and wireless devices. [1] [2] [3]
