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. Depending on the type of weather occurring and the area of the U.
