![]() 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. Radar National Weather Service Sunrise/Sunset Table Thunderstorms and Lightning Weather Service Air Quality Forecast Local Allergy Levels National Allergy. 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.

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. 1 Hour Rainfall Total Doppler Radar for New Tulsa OK, providing current static map of storm severity from precipitation levels. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. the state and around the country, try our new National Radar. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Welcome to our WARN radar Use the layer tools to see the data you. "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.
