As part of recent programmes 1 to update its weather radar network, the Australian Bureau of Meteorology has implemented Doppler capability at some radar sites. The new Doppler radars provide high spatial and temporal resolution observations of the radial velocity of radar targets. Radial velocity has a range of applications, including enhancements to radar data processing and quality control, and high resolution visualisation of the velocity associated with weather features. The primary use of Doppler information is to estimate the wind velocity using precipitation echo. This can be enhanced by the use of clear air echo, primarily from insects, when there is no precipitation present. For example, insect echo can show sea breeze convergence lines. Other non-precipitation echo reveals bushfire smoke propagation and occasionally bird migration and dispersal.
