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. Facebook KCRG-TV9 JWe're streaming LIVE Pinpoint Doppler Radar on : KCRG-TV9 First Alert Weather JA Severe Thunderstorm Watch is in effect until 1 a.m. The higher the dBZ, the stronger the rainrate. KCRG-TV9 - We're streaming LIVE Pinpoint Doppler Radar on. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. Caterer blamed after 51 guests became sick at wedding in Iowa. From reading the weather data at KCRG Radar aka KCRG Pinpoint Doppler Radar to compiling a the stations Weather. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Today Hourly Daily Morning 70 4 Afternoon 76 12 Evening 70 3 Overnight 62 6 Don't Miss Tornado Debris Explodes Into The Air Damaging Winds, Hail, Isolated Tornado Possible Today Several. 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. 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. 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.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. Click on the Layers menu in the bottom right of the radar to select radar options like Current. The higher the dBZ, the stronger the rainrate. Radar Track rain, storms and weather wherever you are with our Interactive Radar. 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. Click here to learn more about our approach to artificial intelligence. Notice the color on each scale remains the same in both operational modes, only the values change. At Gray, our journalists report, write, edit and produce the news content that informs the communities we serve. See the latest Iowa Doppler radar weather map including areas of rain, snow and ice.
