![]() 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. The starting point for official government weather forecasts, warnings, meteorological products for forecasting the weather, and information about meteorology. Hawaii Weather, 7 Day Forecast & Radar KHON2 Weather Alert High Surf Advisory: Kahoolawe, Kauai Southwest, Kona, Maui Leeward West, Niihau, Waianae Coast. 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. See the latest Hawaii Doppler radar weather map including areas of rain, snow and ice. 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. Hocking, Comparison of meteor radar and Na Doppler lidar measurements of winds in the mesopause region above Maui. ![]() 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. Get real time Hawaii weather forecasts and live doppler radar. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). She was a former reporter and copy editor at the Maui News and is now a freelance writer. Values between yellow and white, including blue, represent a relatively moist atmosphere. Values in the red to yellow range represent a dry atmosphere. "Reflectivity" is the amount of transmitted power returned to the radar receiver. Download Band 8 - 6.2 µm - Upper-Level Water Vapor - IR - 1310 UTC Band 8 key: This band shows atmospheric temperatures in Celsius. Other Sites Across the Pacific Only the past 24 hour observations are available for the following sites.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. Using the measurements of horizontal wind profiles made by the University of Illinois meteor radar in Maui, Hawaii (20.7°N, 156.
