Weather radar doesn’t just pick up rain and snow, it can also detect other objects such as birds, insects and even flying debris during tornadoes. A colorful, shimmering spectacle detected by weather radar over the U.S. state of Colorado has been identified as swarms of migrating butterflies. Scientists at the National Weather Service (NWS) first

G’day I’m Matt Collopy, I’m the supervising meteorologist here at the Bureau in South Australia. And we’re here in the Adelaide regional forecasting centre which is where all the forecasts go out for South Australia. Now here in Adelaide the Buckland Park radar is about to go through an upgrade process. So a midlife cycle

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object’s motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements

Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation.

[Voiceover]: Right Here, Right Now. [Pete]: The newest tool that we have here is a second Doppler Radar. No one has two of their own Doppler Radars in the Tri-State and i’m not talking… access to another National Weather Service radar site. I’m talking a second Doppler Radar. Of course you know the capabilities that
