Tune into any TV weather report and you’ll hear the words “Doppler radar” as meteorologists track storms across California. But how does Doppler radar work? And how accurate is it? The concept of ...

Doppler radar stands as the most important modern invention in meteorology, fundamentally transforming how we predict, prepare for, and track severe weather events. Since installations began across ...

What is Doppler Ultrasound Scan? Ultrasound is a high-frequency sound that you cannot hear but it travels through fluid and soft tissues. However, it bounces back, or echoes, when it hits a more solid ...

On a lazy Sunday morning, I asked my Twitter followers what is something they would like to see me write about in this space. Andrew Hatter suggested that I do something on dual-polarization radar. As ...

Researchers have observed the inverse Doppler effect at optical frequencies, using a technique that combines a moving negative-index photonic crystal and heterodyne interferometry. In 1843, Christian ...

Doppler radar uses the Doppler effect to measure the radial velocity of targets in the antenna's directional beam. The Doppler effect shifts the received frequency up or down based on the radial ...

A cutting-edge mobile tool for tracking severe weather will be on display at the National Weather Service office in Dickinson. It gives forecasters much more detail as they try to predict what a storm ...
