Doppler radar is a tool that makes use of the doppler effect to track objects at a distance. This type of technology is most commonly used in meteorology; more specifically used in tracking storms. Doppler radar allows us to pick up a storms size and speed; it can give us this information even days before it hits and area. The doppler radar shown above shows the size and speed of Hurricane Ivan before it hit the Gulf coast. The colors represent the intensity of the storm with red being the strongest.
