The colors are the different echo intensities reflectivity measured in dBZ decibels of Z during each elevation scan. Reflectivity designated by the letter Z covers a wide range of signals from very weak to very strong. So, a more convenient number for calculations and comparison, a decibel or logarithmic scale dBZ , is used. The dBZ values increase as the strength of the signal returned to the radar increases. Each reflectivity image you see includes one of two color scales. The other scale near left represents dBZ values when the radar is in precipitation mode dBZ values from 5 to Notice the color on each scale remains the same in both operational modes, only the values change.

It should provide useful weather information as far west as Glen Innes, south to Kempsey and north to the Gold Coast. There is a tendency to observe areas of false echoes within approximately kilometres of the radar over the sea. These are normally easy to recognise because they are usually the lowest intensity level and randomly scattered with erratic movement from one radar scan to the next. True rain echoes normally have a consistent direction of movement from one scan to the next. Due to its location, this radar is often unable to detect light showers or drizzle beyond a range of kilometres. Although largely removed from the display, anyone to the south west of the radar 50 kilometres or more from Grafton may find an occasional false echo generated by the mountains in this region. There is a small blind spot within a few kilometres of the radar. Charts Australian Charts International Charts.

Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these tweed radar loop dBZ values from being converted to rainfall. Related Links. Show Radar Predictions.

You do not have a default location set To set your location please use the search box to find your location and then click "set as my default location" on the local weather page. Tropical Cyclone Synoptic Charts. Forecast Local Weather Climate. Geographical Situation: The radar is located on an isolated hill about m above mean sea level, just east of Beenleigh. This site provides good low-level coverage, ideal for Doppler observations, of the Greater Brisbane area. The Great Dividing Range to the west and the Lamington Plateau to the south, reduce the radar's view from the south through to the west, affecting its ability to detect weak rainfall from low clouds beyond these obstructions. The radar's coverage, based on detecting echoes at an altitude of m, extends to a range of about km in the north to Tin Can Bay, then it follows a smooth arc through the east to the south-south-east, where it rapidly reduces to about km at Evans Head.

Meteorological Aspects: The radar is well sited to detect rainfall from the west through to the north, the east and to the south.

Voice your opinion or tell us about page issues Non-meteorological echoes: In most cases, processing of the radar signal removes permanent echoes caused by hills, buildings and other solid objects, but sometimes a few slip through. Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. This site provides good low-level coverage, ideal for Doppler observations, of the Greater Brisbane area. True rain echoes normally have a consistent direction of movement from one scan to the next. These usually show up as small, stationary patches of rain, mostly along the higher ground.
