Discuss what the Doppler radar does and the general principle upon which it works.?
What will be the ideal response?
ANSWER: A radar transmitter sends out microwave pulses and when this energy strikes an object, a small fraction of it is reflected and scattered back to the antenna. Precipitation particles are large enough to bounce microwaves back to the antenna. Consequently, a colorful area on the radar screen represents the amount of reflected microwave energy translated into precipitation intensity inside a supercell thunderstorm. Doppler radar can do more than measure rainfall intensity; it can actually measure the speed at which precipitation is moving horizontally toward or away from the radar antenna. Because precipitation particles are carried by the wind, Doppler radar can peer into a severe storm and unveil its winds. Doppler radar works on the principle that, as precipitation moves toward or away from the antenna, the returning radar pulse will change in frequency when compared to the transmitted frequency.?
