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. 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). Because of the direction of the jet stream, wildfire smoke from Quebec, Canada is moving into northeast Wisconsin throughout all the levels of the atmosphere.

One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). WLUK FOX 11 is your source for Balanced News and Severe Weather Coverage for Appleton, Shawano, Sturgeon Bay, Kewaunee, Two Rivers, New London, Bonduel. 1325 East West Highway, Silver Spring, MD 20910 The NWS Radar site displays the radar on a map along with forecast and alerts. 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. The interactive map makes it easy to navigate around. Wluk Tv WeatherWLUK-TV (channel 11) is a television station in Green Bay, Wisconsin, United States, affiliated with the Fox network. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. See the latest Wisconsin RealVue weather satellite map, showing a realistic view of Wisconsin from space, as taken from weather satellites. 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.
