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. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. View other Bedias TX radar models including Long Range, Composite, Storm Motion, Base Velocity, 1 Hour Total, and Storm Total with the option of viewing static radar images in dBZ and Vcp measurements, for surrounding areas of Bedias and overall Grimes county, Texas. The scale of dBZ values is also related to the intensity of rainfall. Base Reflectivity Doppler Radar loop for Bedias TX, providing current animated map of storm severity from precipitation levels. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Disclaimer Information Quality Help Glossary.

Notice the color on each scale remains the same in both operational modes, only the values change. Lubbock Radar Abilene Radar San Antonio Radar Midland Radar. 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).

'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.
