The colors are the different echo intensities (reflectivity) measure in dBZ (decibels of Z) throughout each key scan. "Reflectivity" is the amount of sent power returned to the radar receiver. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to an extremely strong). So, a an ext convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used.

The dBZ values boost as the stamin of the signal went back to the radar increases. Each reflectivity photo you see consists of one that two color scales. One scale (far left) to represent dBZ values when the radar is in clear air setting (dBZ worths from -28 come +28). The other scale (near left) represents dBZ values as soon as the radar is in precipitation setting (dBZ worths from 5 to 75). Notification the color on each scale continues to be the same in both operational modes, just the values change. The value of the dBZ counts upon the mode the radar is in at the moment the photo was created.The scale of dBZ values is additionally related come the intensity of rainfall. Typically, light rain is occurring when the dBZ value reaches 20. The higher the dBZ, the more powerful the rainrate. Depending upon the kind of weather occurring and also the area that the U.S., forecasters usage a collection of rainrates i m sorry are linked to the dBZ values.These worths are approximates of the rainfall per hour, updated each volume scan, v rainfall collected over time. Hail is a great reflector the energy and also will return an extremely high dBZ values. Due to the fact that hail can cause the rainfall approximates to be higher than what is actually occurring, steps are taken to protect against these high dBZ values from being converted to rainfall.
