A DOW (Doppler on wheels) radar truck from the Center for Severe Weather Research scans the heavens for signs of a tornado. Operated by meteorologist Joshua Wurman, the DOW collects wind speed and direction data by measuring the movement of particles—rain, hail, and debris—hidden within storm clouds. The National Weather Service has 121 stationary radar installations around the U.S., but those units can't see fine detail in distant storms. In contrast, DOW trucks can drive within close range of a monster storm to study wind dynamics.
