Weather Radar


The Weather Radar is a type of weather instrument, which is used for locating the precipitation, discriminate its type, calculate its motion, and thus forecast the intensity in the forthcoming days. The term radar broadly means Radio Detection and Ranging. The instrument consists of a parabolic dish which is sheltered in a dome and is mounted atop a high tower.

These days' Doppler radars are used by most of the meteorologists for forecasting the weather. These Weather Radars can also depict the motion of the rain along with the intensity of the precipitation. The meteorologists after collecting the data from the Weather Radar study them thoroughly. Then after analysis the formation of the storm and their potential to cause damages or bad weather is predicted.






The Weather Radar first sends the radar pulses. While moving away from the radar station the radar beams are spread out, which cover a large volume. The directional pulses of microwave radiation are then sent by the Weather Radar. The wave lengths are ten times longer than the diameters of an ice particle or a rain drop. For the smaller particles shorter wave lengths are more useful. Each radar pulse sends back a signal to the radar station. These radar signals are returned from the particles in the air.






Canada has one of the largest Weather Radar Station in the world. There are 31 radars that are spanning across the most densely populated areas of Canada. All radars have a range of 256 km radius.
