Answer:The Doppler radar used in weather forecasting measures the direction and speed, or velocity, of objects such as drops of precipitation. This is called the Doppler Effect and is used to determine whether movement in the atmosphere is horizontally toward or away from the radar, which aides in weather forecasting.
Explanation:
Weather radar is used to locate precipitation, calculate its motion, and estimate its type. This type of radar measures the direction and speed, or velocity, of objects like drops of precipitation. Radars or satellites are particularly good at showing cloud cover. Photographs of cloud cover are none of the advantages of satellites.
Weather radar detects precipitation in the clouds, whereas the Doppler radar takes measurements of winds in clouds seeking to predict severe storms and tornadoes.
