Learmonth Radar Notes

| Radar Type | TVDR 2500 C Band |
| Typical Availability | 24 hours |
The Learmonth radar has 360 degree unimpeded view of the area and is approximately 330 metres above sea level. Radar images can be subject to anomalous propagation of the radar signal which results in false echoes along Ningaloo Reef. Ningaloo Reef is in close proximity to the shore and follows the western coastline of North West Cape. False echoes caused by reflections off the hills in the inland Pilbara can also be observed from time to time in the south-east quadrant of the radar image out to a range of 250 km. This anomalous propagation is easily identified and is displayed as a mass of low intensity echoes constantly changing shape with no apparent direction of movement. True rain echoes normally have a consistent direction of movement from one scan to the next. Echoes within approximately five kilometres of the radar and overhead can be poorly resolved as the scanning elevation is too low.
About Future Radar
Future radar is a new drop-down option available on the Weatherzone radar, allowing you to see where precipitation may fall in the next 30 minutes, 1 hour or 2 hour timeframe. It is a prediction that uses past radar and satellite data to infer the movement and intensity of precipitation. This differs from observed radar which uses physical instrumentation to measure and render precipitation as it happens.
Future radar performs best with broad scale weather systems. However there are limitations in its performance when volatile convective systems develop and change within a short timeframe, as these scenarios provide local impacts that are difficult to predict in terms of speed, direction, intensity and shape.
To help visually distinguish between past timeframes and future timeframes, the radar animation will show predicted radar imagery at reduced opacity. You have the option to turn future radar on or off as it suits your needs.
