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. 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). Local 12 WKRC-TV is the local station for breaking news, weather forecasts, traffic alerts, community news, Cincinnati Bengals, Reds and FC Cincinnati sports updates. 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 NWS Radar page and NWS Satellite page also are available.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. The URL should auto-update with the current settings, allowing for an easy bookmark/favorite. Īdditional URL parameters include lt (center latitude), ln (center longitude), zm (zoom level, 0-12), nolabel (removes flight category icon ID labels), hidemenu (hides the menu options on the lower left), wide (thicken US state boundaries), county (include US counties and other political boundaries based on zoom level), hidefir (hide FIR boundary), zseareas (add the ZSE ARTCC areas), and start (UTC start date/time, YYYYMMDDhhmm format, AWC data goes back up to 2 days, GLM data up to 5 hours). To expand the radar map, keeping the menus/options above and legend below, click ⟺ (include "&invert" in the URL to reverse the background/text colors). Use the + or at the top right to zoom in. By finger pressure or mouse click you can move the area on the map. With the cursor at the bottom left in the center you can view the weather over time. To toggle the lower-left menu visible/hidden, click the ≪ or ≫ button. The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. Left-clicking on the "Speed" area will slow the loop and right-clicking will accelerate the loop, ranging from 0.05 to 5 second interval. and communities in central Ohio, including Dublin, Westerville, Clintonville. When both the flight category and weather are displayed, the flight category icon will be on the inside and the partially-transparent weather color on the outside.Ĭlicking on the map will start/stop the loop. WSYX ABC 6 is On Your Side, providing local news, first warning weather. is the official website for 10TV, Channel 6, your trusted source for breaking news, weather and sports in. Also, GeoColor images may occasionally miss a frame or two. Weather forecast and conditions for Columbus, Ohio and surrounding areas. On the GeoColor satellite images (GOES-West/East cutoff at -114°) the pale bule areas are nighttime areas of lower clouds.
The radar, lightning, visible satellite, IR satellite, GeoColor satellite, SIGMETs/CWAs, and flight categories/weather can be toggled on/off. The above loop uses radar and visible/IR satellite data obtained from Aviation Weather Center (AWC), GeoColor satellite data from NOAA NESDIS-STAR, lightning (GLM) data from NOAA nowCOAST, and observations (for flight category and weather) from MesoWest.
