Doppler weather Radar in city to forecast Accurate Weather


Doppler Weather Radar will be installed in Hyderabad, by which, weather can be predicted accurately. As the part of the modernization programme which was launched by the Indian Meteorological Department (IMD), this radar is being installed at Begumpet, it will be functional by the last week of July.

Meterological department officials said that old and conventional radars were being replaced by IMD with the state of the art S- band DWRs in a phased manner at different locations in the country, especially near the coastal areas. Each radar can cover the 500 km of distance and satellite observations will supplement its observations. Authentic weather forecast will be issued by it for smooth flight operations.


For the installation of the Doppler weather Radar, Rs.15 crore had been spent, few images have been captured by it at the time of trial operational. Before occurrence of a cyclone or heavy rain, more accurate information will be picked up by the radar about the turbulence and wind speed of the atmosphere. It can predict the quantity of rainfall, and rain fall average, detection of thunderstorms which may bring large hail, heavy rain, strong wind.

Doppler Weather Radar would be installed on top of a 6 floors building. Microwaves are released by a doppler, moving weather systems can be monitored by microwaves and it helps the weathermen to analyze weather conditions to predict and to give warning about turbulent thunderstorms or cyclones. Rainfall strength, wind speeds, directions can be measured by it, and cloud formations can be released by it up to 200 km from the radar location. This device is important because rainfall patterns are unpredictable.

This radar is S-band single Polarised Doppler radar and operates on the frequency of 1850 Mhz. Targets can be detected by the radar in a range of 500 km. It can be used for estimation of rainfall in range of the 150 km radius around the radar site and its general weather surveillance range is around 250 km.
