Member of Parliament Rajya Sabha, Iranna Kadadi, recently held a meeting with the Union Minister of Earth Sciences, Kiren Rijiju, in New Delhi and during this meeting, Kadadi earnestly requested the establishment of a cutting-edge Doppler Weather Radar Center in the region of Belagavi.
To the delight of Kadadi, Minister Rijiju responded positively, acknowledging the significance of Doppler radars in line with Prime Minister Narendra Modi’s vision of self-reliance. The Minister highlighted that India is already manufacturing these advanced radars domestically, aligning with the nation’s commitment to reduce dependence on foreign imports. However, he candidly admitted that there has been a slight delay in the process due to the non-importation of certain components.
Nevertheless, Minister Rijiju assured Kadadi that establishing the Doppler Weather Radar Center in Belagavi would be accorded the utmost priority. He pledged to oversee and review this crucial initiative’s progress, ensuring that it swiftly comes to fruition.
Doppler Weather Radars (DWRs) are advanced tools utilized to enhance the precision of long-range weather forecasting and surveillance. These radars operate on the Doppler effect, a principle that reveals changes in frequency when precipitation moves toward or away from the radar. This technology plays a crucial role in predicting tornadoes and gusts of wind.
Each station within the DWR network consists of a radar transmitter, responsible for emitting a microwave signal, and a radar receiver, which detects the reflected signal. While these components are typically located close to each other, they can also be positioned at a considerable distance. As the radar signal encounters moving objects, it reflects off them, and the Doppler effect comes into play, enabling the determination of the speed and direction of these objects.
To provide a comprehensive view of the monitored area, the radar stations within the Doppler network are interconnected with a central processing system. This system amalgamates data from all stations, resulting in a holistic understanding of the weather conditions. Furthermore, the system can be integrated with other weather monitoring equipment, such as weather balloons and satellites, to offer a more comprehensive and accurate depiction of the weather in the region.
