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. 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. WSYX proudly serves Columbus and nearby towns and communities in central Ohio, including Dublin, Westerville, Clintonville, Upper Arlington, Grove City. Farmers are closely watching the weekend forecast because their soybeans and corn need rain. Columbus and central Ohio Weather Radar Skies have stayed cooler and relatively dry throughout the rest of Monday. The higher the dBZ, the stronger the rainrate. WBNS-10TV Columbus, Ohio Columbus News, Weather & Sports. 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. 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. Severe weather moved through parts of Ohio with some areas west and southwest of Columbus under tornado warnings Sunday evening. 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. COLUMBUS, Ohio Firefighters with the Columbus Division of Fire battled a large fire at a vacant building in the Hilltop neighborhood Monday morning. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
