- Christian Doppler, an Austrian scientist, discovered how to measure frequency of radar waves in motion and when the same waves come in contact with objects.
- When using Doppler radar, scientists can determine damaging or deadly weather conditions in advance so people in affected areas can take safety precautions.
- Doppler radar makes it possible for scientists to look inside a storm to locate tornadoes and to gather information to predict the occurrence of tornadoes and severe storms.
- Wind speeds can be determined using Doppler radar by measuring changes in microwave frequencies. These changes are referred to as Doppler effects.
- Weather radar when paired with satellite photography, can provide instant atmospheric details with one snapshot image that spans the entire continent.
- Continuous, instantaneous recordings of Doppler radar make it possible to know weather history for any given location. This capability can be essential for crime scene investigators and search and rescue organizations.
