May 21, 2024 · The most basic product of radar imagery is reflectivity, providing an important snapshot of precipitation intensity and distribution. As radio waves return to the radar site, the system deciphers the difference between lighter and heavier precipitation. The color scale of green, yellow, and red helps us understand the storm intensity.
3 days ago · What distinguishes radar from optical and infrared sensing devices is its ability to detect faraway objects under adverse weather conditions and to determine their range, or distance, with precision. Radar is an “active” sensing device in that it has its own source of illumination (a transmitter) for locating targets.

May 7, 2024 · Radar Indicated. Most tornado warnings cite "radar indicated rotation" as the reason the warning was issued. That means a severe thunderstorm is exhibiting signs of strong rotation on Doppler ...
May 23, 2024 · A warning means weather conditions pose a threat to life or property. People in the path of the storm need to take protective action. An advisory is issued when a hazardous weather or hydrologic event is occurring, imminent or likely. Advisories are for less serious conditions than warnings, that cause significant inconvenience and if caution ...

May 8, 2024 · Quick Summary. Radar relies on the principle of the Doppler effect, which measures the time it takes for reflected waves to return in order to calculate the speed and therefore distance of objects. Radar also measures differences in signal strength to calculate the size, shape, and position of distant objects. Introduction to Radar.
