Hail is a good reflector of energy and will return very high dBZ values. grating a number of small - scale Doppler radar technologies into future. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Ive had a lifelong interest in the weather spanning more than 30 years. 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. Im the lead contributor here at Weather Station Advisor. These images are not maintained by WFO Honolulu. The higher the dBZ, the stronger the rainrate. The Hong Kong Observatory is a government department responsible for monitoring and forecasting weather, as well as issuing warnings on weather-related. Latest State of Hawaii Infrared Image IMPORTANT: The following links for imagery are to servers maintained by the Center for Satellite Applications and Research (STAR), a Division of the National Environmental Satellite, Data, and Information Service (NESDIS). 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. 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.
