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. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. Notice the color on each scale remains the same in both operational modes, only the values change. This view combines radar station products into a single layer called a mosaic and storm based alerts. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). See the latest Connecticut Doppler radar weather map including areas of rain, snow and ice. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). However, we are always seeking additional. The NWS in Tucson, AZ has hundreds of SKYWARN® spotters in its County Warning and Forecast Area, which includes the counties of Cochise, Graham, Greenlee, Pima, SE Pinal and Santa Cruz. Each reflectivity image you see includes one of two color scales. SKYWARN® storm spotters are volunteer citizens who form the nations first line of defense against severe weather. Map time: Mon 00:23:34 GMT-0700 (Pacific Daylight Time) Weather Underground’s WunderMap provides interactive weather and radar Maps for weather conditions for locations. 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.
