![]() ![]() 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. airport delay forecasts, fire danger outlooks, Doppler and satellite images, and thousands of maps. Hail is a good reflector of energy and will return very high dBZ values. 72 15 afternoon 76 0 evening 70 21 overnight 60 2 Don't Miss Actor's Body Identified San Gabriel Mountains 90 Of Georgia Peach Crops Wiped Out The Smoke Is Back So Rare They Said It Was. 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). ![]() 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. See the latest Chicago Doppler weather radar map including areas of rain. 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). This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. "Reflectivity" is the amount of transmitted power returned to the radar receiver. This view combines radar station products into a single layer called a mosaic and storm based alerts.
