Why in news?
The Union Minister dedicated 4 Doppler Weather Radar Systems to the Western Himalayan States of Jammu and Kashmir, Uttarakhand and Himachal Pradesh. He also dedicated 200 Agro Automated Weather Stations to the Nation.
How does Radar work?
Radars is a beam of energy, called radio waves, emitted from an antenna. As they strike objects in the atmosphere, the energy is scattered in all directions with some of the energy reflected directly back to the radar.
What is Doppler Radar?
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance.
These radar systems can provide information regarding the movement of targets as well as their position.
Doppler radars help forecasters to observe rainfall, and the advance of cloud formations over a region and subsequently monitor thunderstorms and lightning in real time.
What is Doppler Effect?
It was first described (1842) by Austrian physicist Christian Doppler.
It is the apparent difference between the frequencyat which sound or light waves leave a source and that at which they reach an observer, caused by the relative motion of the observer and the wave source.
