In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:
Distance and latitude/longitude coordinates are displayed when you mouse over the map. The origin for distance measuring is indicated by a red dot and defaults to either your location, if specified and in range, or the location of the radar/the centre of the map. The origin may be changed by clicking elsewhere on the map.
LocationCeduna Airport Radar TypeWF 100 C Band Typical Availability2145-0215; 0345-0815; 0945-1415; 1545-2015
The Ceduna radar is located at the Meteorological Office which is 3 km east of the township of Ceduna. The surrounding terrain is generally low lying and featureless. The waters of the Great Australian Bight are about 5 km to the southwest of the radar. The radar antenna elevation is 25 metres above sea level. The radar has very good coverage in all directions up to a range of about 250 km. "False echoes" or Anomalous Propagation (AP) can occur on limited occasions in summer where a sea breeze inversion becomes established over the coastal waters. AP can be identified by its static appearance and can normally be distinguished from "real" echoes which exhibit some movement. Heavy rain directly over the radar site can cause attenuation of all signals. Path attenuation can also occur when the radar beam passes through intense rainfall, with the returned signal from cells further along that path reduced.
