Which of the following describes what a Doppler radar does?
A)It determines precipitation size by measuring changes in frequency of the reflected radio wave.
B)It determines precipitation velocity by measuring changes in frequency of the reflected radio wave.
C)It determines precipitation size by measuring changes in intensity of the reflected radio wave.
D)It determines precipitation velocity by measuring changes in intensity of the reflected radio wave.

Question

Quizplus · Accepted Answer

Doppler radar measures the velocity of precipitation by measuring changes in frequency of the reflected radio wave. The frequency shift is caused by the motion of the precipitation toward or away from the radar. Doppler radar can also be used to detect winds, turbulence, and other types of motion in the atmosphere.
