8/15/2023 0 Comments Wbns weather radar columbus ohio![]() 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. 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. 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). 59 1 10:45 pm 58 1 11:00 pm 58 1 Clear feelsLike 56 wind W 9 mph humidity 63 uvIndex uvIndexVal cloudCover 13 rainAmount 0 in 11:15 pm 57 1 Tuesday, June 13 12:00 am 56 1 1:00 am 55. Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. SCIOTO COUNTY, Ohio A teenager was killed when an ATV he was in crashed and rolled over in Scioto County Saturday evening. 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. This is the official app of WBNS and, the CBS affiliate. Our app features the latest breaking news that impacts you and your family, interactive weather and radar, and live video from our newscasts and local events. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
