What is Doppler on Wheels?

Doppler on Wheels (DOW) is a fleet of mobile weather radars designed to provide high-resolution data on severe weather events, such as tornadoes and hurricanes. Developed by the Center for Severe Weather Research (CSWR), these truck-mounted radar systems use Doppler radar technology to measure wind speeds, precipitation intensity, and storm structure in real-time.

Unlike stationary weather radars, Doppler on Wheels can be deployed directly into storm-affected areas, capturing highly detailed information that helps meteorologists better understand storm dynamics. This mobility allows scientists to observe tornado formation, hurricane eyewalls, and other extreme weather phenomena from close range.

DOW has played a crucial role in advancing tornado research, including participation in projects like VORTEX (Verification of the Origins of Rotation in Tornadoes Experiment). The data collected helps improve weather forecasting models and enhance early warning systems, ultimately increasing public safety during severe weather events.

These mobile radar systems have also been featured in storm-chasing documentaries and educational outreach programs, providing the public with an up-close view of the power of nature.
