Weather radar, or weather surveillance radar (WSR), is a system installed in aircraft to detect weather conditions. It provides pilots with information to avoid, not penetrate, adverse weather. Weather radar is a type of radar that helps: Locate precipitation Calculate the motion of precipitation Estimate the type of precipitation, such as rain, snow, or hail Forecast the future position and intensity of precipitation Predict where rain will move next and how intense it will be  Modern weather radars are mostly doppler radars, which can detect the motion of rain droplets as well as the...
