Highlights
Weather radar is a device that detects precipitation¿wind, rain or other ground systems like tornados¿through the use of energy pulses. Radar allows forecasters to track a hurricane when it's still hundreds of miles out at sea, or as much as days before landfall. It is the single most important device for tornado detection, since a single hurricane can spawn dozens.
The radar does not "see" these systems like weather satellites, but is used to measure elements of storms that escape other technology. Radar does this by sending out a pulse of energy, and then listening for its return signal. The signal returns after it bounces off an object like rain or snow.

Weather radar is a device that detects precipitation¿wind, rain or other ground systems like tornados¿through the use of energy pulses. Radar allows forecasters to track a hurricane when it's still hundreds of miles out at sea, or as much as days before landfall. It is the single most important device for tornado detection, since a single hurricane can spawn dozens.
The radar does not "see" these systems like weather satellites, but is used to measure elements of storms that escape other technology. Radar does this by sending out a pulse of energy, and then listening for its return signal. The signal returns after it bounces off an object like rain or snow.
The amount of energy in the returning signal, and the time it takes to return, determines the distance and range of the object. Over the last decade, improvements in technology have resulted in Doppler Radar that also detects the rate of speed at which a target is moving toward or away from the radar.
Radar is not a perfect instrument, and what it detects has to be verified with satellites, weather buoys, or the human eye. In 2006, an apparent storm system along the Mississippi River turned out to be a huge hatching of mayflies. In 2005, passengers on board a Hong Kong flight were seriously injured because the weather radar was pointed too low to spot a strong system of turbulence. In mountainous areas of the United States, radars can be ineffective since they cannot "see" through mountains.
The next generation of weather radar systems will give meteorologists more detailed, three-dimensional images of storms, according to the National Weather Service. The new technology, called multi-beam radar, will give the impression of being inside a storm and will require extensive training for meteorologists. While conventional weather radar shoots one beam at a time, the new system will shoot multiple beams at different angles to provide more complete coverage of atmospheric conditions. Multiple-beam systems are 10 times faster than traditional radar and that could allow meteorologists to issue more timely warnings.
