Sand goanna the scent is stronger. Upon identifying this difference in scent strength the sand monitor can alter its direction accordingly. Sand goanna The sand goanna ("Varanus gouldii" ) is a species of large Australian monitor lizard, also known as Gould's monitor, the sand monitor, or racehorse goanna. In some Aboriginal languages, the sand goanna is called "bungarra", a term also commonly used by non-Aboriginal people in Western Australia. In Pitjantjatjara and other central Australian languages it is called "Tingka". The name "sand monitor" can be used to describe various other species. The specific name, "gouldii", is a Latinised form of the
Hail spike the multiple path at a later time than the energy that came back directly from the hail to the radar. Both are however on the same radial angle from the radar as the antenna did not have the time to turn significantly. The multipath echoes are then analyzed on the radar display as echoes extending in a radial direction behind the actual location of the hail/heavy rain core. The loss of energy by due to multiple reflections means weaker return echoes. The hail spike region has thus comparatively quite weaker echoes than the echoes directly from the hail or heavy
