Base Reflectivity Doppler Radar for Chattanooga TN, providing current static map of storm severity from precipitation levels. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.Update to the mapping background in the radar tile and page to give it a new modern look. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change.

This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. Each reflectivity image you see includes one of two color scales. Talk to News 12 anchors, reporters and meteorologists. This view combines radar station products into a single layer called a mosaic and storm based alerts. The dBZ values increase as the strength of the signal returned to the radar increases. ![]() So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). ![]() "Reflectivity" is the amount of transmitted power returned to the radar receiver. ![]() The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
