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. THUNDERSTORMS: Scattered strong to severe thunderstorms are possible this afternoon WIND: Gusts near/over 30 MPH possible today. Hail is a good reflector of energy and will return very high dBZ values. Because the earth is round and the radar. There is a notable constraint to radar data though. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. This data is gathered from over a hundred radar towers located across the US. 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. 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). weather radar, radar, San Diego radar, doppler radar, interactive radar, KFMB, San Diego, California, news, local news, breaking news, traffic, weather. 'Reflectivity' is the amount of transmitted power returned to the radar receiver. Other common terms for weather radar are weather surveillance radar (WSR) and Doppler weather radar.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. Base Reflectivity images are available at several different elevation angles (tilts) of the antenna and are used to detect precipitation, evaluate storm structure, locate atmospheric boundaries and determine hail potential.

The data can be analyzed to determine a storm's structure and the possibility they could become severe. Doppler Weather Radar Map tiles by Stamen Design, under CC BY 3.0.

A base reflectivity radar is a display of echo intensity (reflectivity) measured in dBZ (decibels of Z, where Z represents the energy reflected back to the radar). Quick and easy access to current Doppler radar maps and weather forecasts for your area. green is rain, pink is a mix of rain, freezing rain, sleet, and/or snow and blue is snow. Sign up to receive email alerts when severe weather happens in your area. The precipitation type is indicated by different colors. Zoom in to your street or out to your region and view past and futurecast radar. Alerts for severe weather go to your home screen and cue an audio alert.

The Surprising Way Weather Affects Your MoodĪbout this map: The Precipitation Type Radar is the base reflectivity radar with areas of precipitation split into their respective precipitation types (rain, snow, hail, etc.). Live interactive radar with many layering options lets you track the storms around you.
