The transmitter samples the environment by sending out a pulse of energy that reflects off objects (like raindrops) and scatters the energy pulse in all directions. The antenna is made up of a transmitter and a receiver. The radar dome, which many people say looks like a big soccer ball or volleyball, protects a 28-foot-wide antenna. Doppler radar technology also enables meteorologists to forecast the location and severity of weather with greater accuracy, which has resulted in improved public safety.

This helps meteorologists detect near-ground wind shears, which are dangerous to aircraft. (Photo: NOAA)Ĭonventional radar provides information about the location and intensity of precipitation associated with a storm, while Doppler radar adds the capability to discern air motions within a storm. Weather Bureau’s first experimental Doppler weather radar unit, obtained from the U.S. Forecasters using Doppler radar can issue more timely and accurate hazardous weather information than ever before. conventional radarĭoppler radar has been one of the most important technological advances in hazardous weather prediction over the past 30-plus years.

Now, let’s crack open that shell and get to the nuts and bolts of how it came to be and how it works. In a nutshell, Doppler radar is a specialized tracking system that uses the Doppler effect (Doppler shift) to determine the location and velocity of storms and precipitation.
