Doppler on Wheels

Doppler on Wheels (DoW) is a mobile weather radar system mounted on a truck that helps scientists study severe weather, like tornadoes and storms. It uses the Doppler effect—similar to how a siren’s pitch changes as it passes—to measure the speed and movement of rain, wind, and storm clouds. By continuously moving through and around storm areas, DoW provides real-time, high-resolution data, allowing meteorologists to better understand storm structure and dynamics. This information is crucial for accurate weather forecasting and early warnings, ultimately helping to save lives and protect property.
