These scans are interpreted by a computer and translated into an image. Animate the interactive future radar forecast in motion for the next 12 to 72 hours. Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation. High-resolution predictive weather radar. You may notice slower loading during times of active weather and heavy website traffic. A complete set of scans takes around 5 minutes to complete. Additionally, simulated radar is derived from numerical models, and the output may differ from human-derived forecasts. 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. Doppler radars scan the horizon in 360˚ degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). radar data which gives us a feel for how much water there is. About 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.). This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second. 'At 3:27 a.m., Doppler radar tracked a strong thunderstorm 7 miles south of Florala, moving northeast at 55 mph,' according to the weather service. See a real view of Earth from space, providing a detailed view of. Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. The Next Generation Weather Radar (NEXRAD) system is a network of 160 high-resolution S-band Doppler weather radars jointly operated by the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Current and future radar maps for assessing areas of precipitation, type, and intensity. The radar instrument receives a signal from this reflected energy during its listening period. A small fraction of the scattered energy is directed back toward the radar. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. The radar emits a burst, or pulse, of energy. NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy.
