Doppler radars are very important to meteorologists because it can accurately view the motion of a weather system. This can lead to future predictions of the weather system, such as if it might later form tornadoes. This specific type of radar works by beaming a microwave signal at an object, and by using the doppler effect, it can produce velocity data about the object from a distance. It is mainly used to produce atmospheric profiles of weather systems (clouds) such as its motion and composition. This system is a form of active radar where events can be viewed in real time. The above still image is from a polarimetric doppler radar which can differentiate between horizontal and vertical components of an object. This image shows the intensity of a storm by use of color shading passing through southern Florida. The closer to red the color is the more intense the storm is.
