Sri Lanka is set to establish a Doppler weather radar in Puttalam, thanks to funding from the Japan International Cooperation Agency (JICA). This initiative is part of a broader effort to improve the country’s weather prediction and disaster preparedness.
The island nation, surrounded by vast sea areas like the Bay of Bengal, the Arabian Sea, and the southern Indian Ocean, faces complex weather patterns. The central terrain and proximity to the equator add further challenges, making accurate weather forecasting a critical need.
Meteorological phenomena account for over 90% of major disasters in Sri Lanka, with frequent incidents of heavy rainfall leading to floods and landslides. These events, often triggered by squall thunderstorms, depressions, and cyclones, underscore the importance of accurate and timely weather monitoring.
The Doppler Weather Radar Network project initially planned to install two radar systems in Puttalam and Pottuvil. However, due to economic constraints from the COVID-19 pandemic and rising costs, it was decided in 2019 to focus on constructing a single radar station in Puttalam. This project is fully funded by a generous grant of 2,663 million JPY from JICA.
The advanced radar system will provide real-time quantitative precipitation measurement and nowcasting capabilities, significantly enhancing the Department of Meteorology’s ability to forecast rainfall and respond to rapidly changing weather conditions. This improvement is crucial for disaster mitigation and response.
The foundation stone for the Puttalam Doppler Radar Station will be laid on December 23rd, with distinguished attendees.
