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. Paris, TX Doppler Radar Weather - Find local 75460 Paris, Texas radar loop and radar weather images. 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. Paris Texas Weather Radarthe most current and reliable 14 day weather forecasts, storm alerts, reports and information for Paris, TX, US with The Weather. 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. Doppler radar was tracking a strong thunderstorm near. The dBZ values increase as the strength of the signal returned to the radar increases. View our Mega Doppler Southeast Texas weather radar map for current weather conditions for Southeast Texas and the surrounding areas. 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. 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.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. The higher the dBZ, the stronger the rainrate. The value of the dBZ depends upon the mode the radar is in at the time the image was created. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). See the latest Texas Doppler radar weather map including areas of rain, snow and ice. The dBZ values increase as the strength of the signal returned to the radar increases.
