AZ WEATHERRADAR HOW TO

Other common terms for weather radar are weather surveillance radar (WSR) and Doppler weather radar. 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. 'Reflectivity' is the amount of transmitted power returned to the radar receiver. The radar products are also available as OGC compliant services to use in your application. The data can be analyzed to determine a storm's structure and the possibility they could become severe. The NWS Radar site displays the radar on a map along with forecast and alerts. Covering all of Phoenix Arizona, Mesa, Chandler, Gilbert, Tempe. 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). Live local weather, 7-day forecast, current weather conditions, and severe weather alerts. green is rain, pink is a mix of rain, freezing rain, sleet, and/or snow and blue is snow. The precipitation type is indicated by different colors.

Why You Should Check The Local Weather Before Planning Your DayĪbout 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.).

How to Use the Tide Schedule to Your Advantage.

The Surprising Way Weather Affects Your Mood.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. Now 11p Map Options Layers and Styles Specialty Maps Make your map your own. Typically, light rain is occurring when the dBZ value reaches 20. Show Low, AZ Radar Map Rain Frz Rain Mix Snow Show Low, AZ Slight chance of rain over the next 6 hours. 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. Arizona animated weather radar image displaying locations and movement of rain, snow and ice over the previous three hours. 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). Click the precipitation chart to see the total precipitation. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Click the 500-Millibar chart to see a larger version of the chart with temperature and winds added. View other Benson AZ radar models including Long Range, Composite, Storm Motion, Base Velocity, 1 Hour Total, and Storm Total with the option of viewing animated radar loops in dBZ and Vcp measurements, for surrounding areas of Benson and overall Cochise county, Arizona. Each reflectivity image you see includes one of two color scales. Base Reflectivity Doppler Radar for Benson AZ, providing current static map of storm severity from precipitation levels. AZ AZ IMUTH, azimuthal position, in radians. The dBZ values increase as the strength of the signal returned to the radar increases. VD VELOCITY ( Doppler ), Doppler velocities in a SAMPLE VOLUME, in km / hr. infoTodays and tonights Phoenix, AZ weather forecast, weather. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Check out our current live radar and weather forecasts for Phoenix, Arizona to help plan. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong).

The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
