Doppler Radar

The doppler weather forecast is used to research about weather so that people can make predictions on precipitation, to calculate its motion and to estimate its type of rain hail snow etc. People mostly use pulse doppler-radar so that they can determine the motion of rain dopplers. How waves are used to show that weather is happening is by we see the waves in colors of the rainbow (ROYGBIV). Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. A Doppler Radar is combined with satellites which allows forecasters to provide us with upcoming thunderstorms, tornadoes or any other storm that could cause damage. Doppler Radars work by the satellites measuring the changes in the frequency of the signal the radar gets to conclude the wind.
