Chennai, Dec 29 (NationPress) In a significant advancement for weather forecasting and disaster preparedness, Tamil Nadu is poised to install five new Doppler Weather Radars (DWRs) to bolster cyclone tracking, rainfall monitoring, and early warning systems throughout the state.
The radars will be strategically placed in Kanyakumari, Tiruchirappalli, Coimbatore, Yercaud, and Ramanathapuram.
Among the five proposed radars, three will be implemented under the Central government’s flagship initiative, "Mission Mausam", while the other two will be integrated through a specialized program of the Tamil Nadu Disaster Risk Reduction Agency.
This expansion is anticipated to greatly improve weather monitoring, particularly in areas currently lacking sufficient radar coverage.
Currently, Tamil Nadu is served by eight Doppler weather radars, some of which are located within the state while others are positioned in adjacent regions.
These include two radars in Chennai: an older S-band radar at Chennai Port and an X-band radar at the National Institute of Ocean Technology (NIOT).
Coastal surveillance is aided by an S-band radar at Sriharikota, a C-band radar at Kalpakkam, and yet another S-band radar at Karaikal.
Inland areas benefit from radars situated in Thiruvananthapuram, Kochi, and Sulur.
However, officials have noted that extensive regions of central Tamil Nadu, including Tiruchirappalli, and southern districts like Kanyakumari, remain inadequately covered.
These areas are particularly susceptible as they receive rainfall from both the southwest and northeast monsoons and are often affected by cyclonic systems emerging from the Bay of Bengal.
Officials elaborated on the rationale behind the new radar sites, emphasizing the necessity for continuous weather monitoring, increased radar density in coastal and hilly regions, and improved coverage in disaster-prone and densely populated zones.
The replacement of outdated equipment and the assurance of redundancy in vulnerable areas were also pivotal factors.
With the addition of these five radars, Tamil Nadu’s weather surveillance network is expected to be significantly fortified, enhancing the precision of forecasts, improving early warning capabilities, and enabling authorities to respond more efficiently to cyclones, heavy rainfall, and extreme weather events.
Point of View
The initiative to install five new Doppler Weather Radars in Tamil Nadu reflects a commendable commitment to improving weather forecasting and disaster management. Such advancements are essential for safeguarding communities against the increasing frequency of extreme weather events. As a nation, we must continue to prioritize innovations that enhance public safety and resilience.
