![]() 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. Stewart McKechnie ( POD Associates, Inc. Hail is a good reflector of energy and will return very high dBZ values. current theories of heating are discussed, and specific further. 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. High temperatures are forecast to warm a few to around 9 degrees above yesterdays readings over northern and eastern areas, but there will be a few degrees of cooling across the southwest. Typically, light rain is occurring when the dBZ value reaches 20. NOAA National Weather Service Albuquerque, NM. Want to know what the weather is now Check out our current live radar and. The scale of dBZ values is also related to the intensity of rainfall. Tucson Weather Tomorrow Morning7 Day & Night Weather Forecast for Tucson, AZ. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Check current conditions in Tucson, AZ with radar, hourly, and more. Notice the color on each scale remains the same in both operational modes, only the values change. weather forecast, weather conditions and Doppler radar from The Weather Channel and Weather.

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). See the latest Florida Doppler radar weather map including areas of rain, snow and ice. "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.
