Grafton loop radar

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 grafton loop radar range of signals from very weak to very strong. So, a more convenient number for calculations and comparison, a decibel or logarithmic scale dBZgrafton loop radar, is used. The dBZ values increase as the strength of the signal returned to the radar increases.

Grafton loop radar

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. The value of the dBZ depends upon the mode the radar is in at the time the image was created. The scale of dBZ values is also related to the intensity of rainfall. Typically, light rain is occurring when the dBZ value reaches The higher the dBZ, the stronger the rainrate.

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.

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. 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. The dBZ values increase as the strength of the signal returned to the radar increases. It's a problem 4 days ago. True rain echoes normally have a consistent direction of movement from one scan to the next.
