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. 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. Choose your main map layer, then add on any additional. Now 12a Map Options Layers and Styles Specialty Maps Make your map your own. 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. Frz Rain Mix Snow Kenton, OH Rain likely to end around 2:00 am. 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. WSYX proudly serves Columbus and nearby towns and communities in central Ohio, including Dublin, Westerville, Clintonville, Upper Arlington, Grove City. The value of the dBZ depends upon the mode the radar is in at the time the image was created. COLUMBUS, Ohio Firefighters with the Columbus Division of Fire battled a large fire at a vacant building in the Hilltop neighborhood Monday morning. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. Columbus and central Ohio Weather Radar Skies have stayed cooler and relatively dry throughout the rest of Monday. 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.
